Python

Faster Debugger

Python 3.6 debugging is now up to 40x faster! We have been able to use some new features in Python 3.6 to radically improve the performance of the PyCharm debugger. Is your project not on 3.6 yet? Python 3.5 (and older) debugging got up to two times faster as well. If you’d like to know more: read the interview with our developer.

New and Improved Test Runners

PyCharm has now adopted the TeamCity API for test runners. This means that test configurations will be consistent between the IDE and CI builds. This allows us to use the native test runners, and will make integration of new test runners in the future easier. Read about the technical details here.

Support for the six Library

If you’d like to upgrade to Python 3, but still need to support Python 2 for a while, you can use the six library. The six library enables you to write a single codebase that can run on both Python 2 and Python 3 interpreters. PyCharm now has accurate code completion and code insight for six.

Web Development

Django, Flask & Pyramid pro only

PyCharm has been updated to support all current versions: Django 1.10, Flask 0.12, and Pyramid 1.8.2.

Vue.js pro only

Vue.js is a rapidly growing new JavaScript framework. Get the Vue.js plugin from the JetBrains repository (Settings | Plugin | Install JetBrains Plugin) to try it out in PyCharm 2017.1! The new version of PyCharm adds Vue autocomplete and code assistance, which also works in multiple languages within .vue files.

JavaScript Unit Test Status Gutter Icons pro only

Unit tests are a great tool to check against regressions, but sometimes you want to change something which breaks your tests. Now you can see right in the editor which tests need an update, and if you’re using Mocha or Jest you can debug them right from there.

Support for Jest pro only

If you’re using React, you should try Jest – Facebook’s JavaScript unit testing framework. In PyCharm 2017.1 we support running and debugging Jest tests. And of course if you spot a failing test, you can just double-click it to go to the test’s source.

Database Tools

Editor Colors pro only

Bad things happen when you think you’re working on staging, but you accidentally opened an SQL prompt on your production server instead. To prevent this, now you can set your editors to different backgrounds.

Version Control

Improved Log Viewer

Our log viewer has a couple of small useful improvements: you can now search commits using regex, and toggle case sensitivity.

File History

We’ve improved our file history panel. For example, you can now easily toggle between seeing only the commits on the branch you’re currently on, or the commits on all branches.

Remote Development

SSH Multi-Factor Authentication pro only

If you’re security-conscious, you may have hardened your server’s SSH access with 2-factor authentication. PyCharm now supports connecting to SSH servers that are protected with Google Authenticator.

Native Docker for Mac pro only

PyCharm 2017.1 supports Docker for Mac using native unix sockets. No more need to use SOCAT to connect your IDE to Docker.

Data Science

Data View for Pandas DataFrames and Numpy Arrays

When doing data science, seeing the data you’re working on makes the work a lot easier. That’s why we’ve taken our DataFrame and Numpy Array viewer, and evolved them into a dedicated Data View pane. Complete with tabs to easily watch multiple datasets.

Remote Jupyter Notebooks pro only

Jupyter Notebooks are a great way to do research. If you do research in a team, you’ll want to share your notebooks with your team members. That’s why PyCharm 2017.1 supports connecting to Jupyter Notebooks on a shared server.

Platform Improvements

Zero-Latency Typing

Lower latency typing means for a better typing experience. Pavel Fatin, one of our developers, worked hard to get the latency down as low as it can go.

Semantic Highlighting

When enabled, semantic highlighting will make it easy to see where a variable is used at a glance. Check out our blog for more information.

Ctrl+Click on Links in Terminal

A small improvement to make your life easier: hold Ctrl and click any link in the terminal to open it in your browser.

Find in Path Dialog

We’ve reworked our Find in Path dialog: it’s cleaner, easier to use, and sleeker-looking! Try it yourself: right-click a folder in your project and select ‘Find in Path.’

If you’re interested in PyCharm Professional, you should also check out what’s new in WebStorm 2017.1 and in DataGrip 2017.1. The Professional Edition of PyCharm comes with the JavaScript features from WebStorm, and the database features from DataGrip.

Python Tools

Create Django projects with remote interpreters pro only

PyCharm now supports creating Django projects with a remote interpreter straight from the new project screen. If you develop in VMs, Docker containers, or on remote machines, your workflow just got easier.

Django forms in class-based views pro only

PyCharm now understands the forms context in class-based views. It shows forms-specific autocompletion and suggestions in the same way it does for function-based views.

Python console copy-paste made easier, and more

Have you ever written some code in the Python console to test it, before including it in your project? In PyCharm 2016.3 you can now quickly copy-paste code from the built-in console to your project files. Your code will automatically be formatted. Further: If you're launching the console as a part of your run configuration, you can now use the variable viewer to inspect all your variables. We've also fixed some issues with multi-line commands, added tab completion for IPython, and many more things.

Variable explorer

When debugging, your own variables are usually most relevant. That's why we've hidden the special variables until you need them. And if you do want to explore them, simply expand them.

Open the Numpy Array and DataFrame viewer straight from the debugger

You can also explore pandas dataframes, and numpy arrays, straight from the debugger in PyCharm 2016.3.

Python 3.6

The new version of Python will be released soon, and PyCharm 2016.3 is well prepared. It already supports type annotations, f-strings, underscores in numeric literals, asynchronous generators, and asynchronous comprehensions.

Terminal with Virtualenv pre-activated

Is activating your virtualenv the first thing you do when opening a terminal session? We just took care of that for you. When you open the terminal in Pycharm 2016.3, it will automatically activate the virtual environment associated with the project you're working on. Auto virtualenv is supported for bash, zsh, fish, and Windows cmd. You can customize your shell preference in Settings (Preferences) | Tools | Terminal.

Per-branch coverage pro only

If you enable the option, PyCharm can now show you whether you've covered all code branches, right next to the point where the code branches. Enable the option in PyCharm 2016.3 by going to Settings (Preferences) | Build, Execution, Deployment | Coverage | Python coverage.

Per-line vmprof profiling pro only

If you use vmprof, PyCharm will now show performance information right next to your code. You can see at a single glance which lines need closer attention. To start using vmprof, simply install the vmprof package from PyPI into your project. You can use the PyCharm built-in package manager (Settings | Project | Project Interpreter) to install the package. After running your code with profiling enabled, the performance information will be displayed in your editor.

Docker-compose support improved: multiple compose files & environment variables pro only

More and more developers use environment variables to configure their applications, PyCharm now makes it easier to set environment variables for Docker compose run configurations. If you want to further tailor your environment with a compose file extension, this has also been made easy.

Web Tools

Angular 2 CLI support and more web development improvements pro only

PyCharm 2016.3 comes with many of the new features from WebStorm 2016.3. For example, if you have Angular CLI installed, you can use it to generate new components, directives, services, and other blueprints straight from the ‘New…' popup. Other new features include Flow type checking support and Stylelint CSS linting. Check the WebStorm 2016.3 page for more.

Version Control System Improvements

Faster log search

The version control integration in PyCharm 2016.3 is faster than ever. The improved log screen (View | Tool Windows | Version Control, Log tab) shows the previous commits, and allows you to quickly search for commits. You can also filter your log search by branch, commit author, and filesystem path.

Resolve merges

Resolving merge conflicts is everybody's favorite part of the job. Unfortunately we can't make it more fun, but we can make it easier for you. The new merge resolve interface has code highlighting and other code navigation features built-in. In some cases it will even let you automatically resolve conflicts with a single click.

Undo commit

Have you ever checked in some code, only to quickly realize you forgot something? You can now undo your last commit (if it hasn't been pushed yet) straight from the log. For example, for git repositories this executes git reset --soft HEAD~1. Hint: you can always see what PyCharm did by checking the console tab of the version control window.

Git remote management

We've added a graphical interface for managing git remotes. You can manage your remotes by navigating to VCS | Git | Remotes, or by adding them straight from the ‘Push commit' screen.

IDE Improvements

Database Improvement: Edit many cells at once pro only

Sometimes you want to change a lot of cells simultaneously, you can now select them all and change them in one go! Of course for this to work, the fields need to have the same type, and they shouldn't be set to have unique values in your database. To see more new database improvements, check out what's new in DataGrip, our new database IDE. PyCharm 2016.3 bundles many DataGrip features.

Editor improvements: Fira Code bundled, and style changes

Did you want to check out the new support for ligatures, but haven't had a chance to get a font with them yet? We now include Fira Code with PyCharm. If you want to see what it looks like, select Fira Code in Editor | Colors & Fonts | Font. Be sure to turn on the font ligatures feature on the same settings page. We've also introduced new flat file icons.

Python Tools

vmprof Profiler Support pro only

For those who care about performance, PyCharm provides profiling support. Additionally to the previously supported cProfile and Yappi profilers, PyCharm 2016.2 brings support for vmprof, the sampling (statistical) Python profiler written in C and developed by members of the PyPy team. It works for Python versions 2.7 through 3.5, CPython as well as PyPy, and supports Linux, macOS and Windows.

Pandas Dataframes Viewer

PyCharm has had a special array viewer for NumPy arrays for a couple of years. PyCharm 2016.2 brings Pandas Dataframes support – a must-have feature for scientific developers and data scientists. Thanks to our user Yuli Fiterman for contributing this feature!

Thread Suspend Option

Previously, when the PyCharm debugger reached a breakpoint during execution, only the corresponding thread was suspended while others kept running. Now there is a Suspend option with two values: All and Thread. ‘All' makes all threads stop at once whenever a breakpoint is hit. With the ‘Thread' option, only the corresponding thread stops.

Function Return Values
in the Debugger

The new option has appeared in Debug tool window: Show Return Values. Function return values are now shown in the PyCharm's debugger after stepping out from a function.

Package Installation from
requirements.txt

PyCharm 2016.2 understands the syntax of extra options in requirements.txt files, automatically installing all the specified extras. For example, now you can use the following code in your requirements.txt files:

requests[security]
ipython [notebook]

Configuration for
Optimize Imports

Optimize Imports has been a neat feature for many years. In PyCharm 2016.2 the new dedicated setting for Optimize Imports action appeared. It allows you to configure how imports in the current file are sorted and arranged in groups.

Postfix Code Completion

Postfix code completion helps reduce backward caret jumps as you write code. It lets you transform an already typed expression to another one based on the postfix you've added and the context of the expression. It has been improved with the “main” and “print” postfix templates extracting your [expression].main and [expression].print code snippets respecting Python 2 and Python 3 versions.

Lettuce Scenario Outlines

In PyCharm 2016.2 BDD support got an important improvement. PyCharm now recognizes Scenario Outlines sections in Lettuce feature files. Scenario Outlines are supported for Lettuce version 0.2.22 and higher.

IDE Improvements

Support for Ligatures

The editor in PyCharm now supports fonts with programming ligatures, like Fira Code, Monoid, Hasklig and  PragmataPro. Enable this in Preferences | Editor | Colors and Fonts | Font.

The Inspection Tool
Improvements

The Inspection tool window has been redesigned for better ergonomics: now code location for each of the problems is displayed along with controls to either apply a quick-fix or suppress an inspection.

Editor Background Image

Customize your IDE's look by choose a background image for the editor and the IDE frame. Search for ‘Set Background Image' with the Search Everywhere action double Shift.

Regex Support
Improvement

Coding assistance for Regex has been extended with better error reporting, and code completion is now available for named group references.

Unversioned Files Handling

The Commit dialog now shows unversioned files (so you don't forget to commit something important).

Improvements in
Working with Patches

Working with VCS patches has never been easier. With PyCharm 2016.2 a patch can be applied from the clipboard (when the IDE obtains focus), or by dragging a file into the IDE. In case a file has been changed since a patch was created for it, but PyCharm cannot find its original revision, you'll be prompted to apply the patch using a Merge-like dialog. Also, the Apply Patch dialog provides the Show Diff action to compare the patch to your local version.

The VCS Log Viewer

The Log viewer for Git and Mercurial continues to get better:

  • It loads in the background on every change (a commit, fetch, rebase, etc.), so it's always ready when you open it.
  • We've reworked the way the Log shows the loading progress. Now, when refreshing, a thin stripe appears under the toolbar.
  • When you select several commits, you see all commit details.
  • Ctrl+L can be used for navigating to the Filter field.

Database Tools
Improvements pro only

  • Code completion for database names in Data Sources and Drivers.
  • Import of CSV, TSV (DSV) files to a database.
  • Language injections to SQL code.
  • Table Editor provides completion for column values.
  • PostgreSQL support has been extended to Schema Search Path, Rangetypes and types with TimeZone.
