Tabs and Indents

Item

Description

Use tab character

  • If this checkbox is selected, tab characters are used:
    • On pressing the Tab key

    • For indentation

    • For code reformatting

  • When the checkbox is cleared, PyCharm uses spaces instead of tabs.

Smart tabs

  • If this checkbox is selected, the part of indentation defined by the nesting of code blocks, is made of the tabs and (if necessary) spaces, while the part of indentation defined by the alignment is made only of spaces.

  • If this checkbox is cleared, only tabs are used. This means that a group of spaces that fits the specified tab size is automatically replaced with a tab, which may result in breaking fine alignment.

The Smart Tabs checkbox is available if the Use Tab Character checkbox is selected.

Tab size

In this text box, specify the number of spaces included in a tab.

Indent

In this text box, specify the number of spaces (or tabs if the Use Tab Character checkbox is selected) to be inserted for each indent level.

Continuation indent

In this text box, specify the number of spaces (or tabs if the Use Tab Character checkbox is selected) to be inserted between the elements of an array, in expressions, method declarations and method calls.

Keep indents on empty lines

If this checkbox is selected, then PyCharm will keep indents on the empty lines as if they contained some code.
If this checkbox is cleared, PyCharm will delete the tab characters and spaces.

Spaces

Use this tab to specify where you want spaces in your code. To have PyCharm automatically insert a space at a location, select the checkbox next to this location in the list. The results are displayed in the Preview pane.

Wrapping and braces

In this tab, customize the code style options, which PyCharm will apply on reformatting the source code. The left-hand pane contains the list of exceptions (Keep when reformatting), and placement and alignment options for the various code constructs (lists, statements, operations, annotations, etc.) The right-hand pane shows preview.

Alignment takes precedence over indentation options.

Right Margin (columns)

Use the Hard wrap at field to specify a margin space required on the right side of an element. If you select Default option then a value of the right margin from the global settings is used.

Wrap on typing

Use the Wrap on typing settings to specify how the edited text is fitted in the specified Hard wrap at. You can select one the following options:

  • Default - in this case PyCharm uses the Wrap on typing option that is specified in the global settings.

  • Yes - in this case PyCharm uses the value specified in the Right Margin field.

  • No - in this case this option is switched off and a line can exceed the value specified in the right margin.

Visual guides

Use the Visual guides field to specify multiple right margins. You can leave a default value or enter the number of spaces for your margin. If you want to specify several margins, enter numbers separated by comma.

Keep when reformatting

Use the checkboxes to configure exceptions that PyCharm will make when reformatting the source code. For example, by default, the Line breaks checkbox is selected. If your code contains lines that are shorter than a standard convention, you can convert them by disabling the Line breaks check box before you reformat the source code.

Blank lines

Use this tab to define where and how many blank lines you want PyCharm to retain and insert in your code after reformatting. For each type of location, specify the number of blank lines to be inserted. The results are displayed in the Preview pane.

Item

Description

Keep Maximum Blank Lines

In this area, specify the number of blank lines to be kept after reformatting in the specified locations.

Minimum Blank Lines

In the text boxes in this area, specify the number of blank lines to be present in the specified locations.

Imports

This table lists actions to be performed when imports are optimized.

Item

Description

Sort import statements

Select or clear this checkbox to enable or disable sorting imports within individual import groups according to PEP 8.

The following checkboxes affect the sorting order.

Sort imported names in "from" imports

If this checkbox is selected, the imports in the from ... import ... statements are sorted alphabetically.

Not selected

Selected

from sys import version, path, modules

from sys import modules, path, version

Sort plain and 'from' imports separately within a group

If this checkbox is not selected, the imports from the same module, regardless of their type, are grouped together, but so that import statements go first, and from ... import ... statements go next.

If this checkbox is selected, the imports are at first sorted by there type (first import, next from ... import ...), and then alphabetically.

Not selected

Selected

import os from os import getenv import sys from sys import path

import os import sys from os import getenv from sys import path

Sort case-insensitively

This checkbox enables case-insensitive sorting of the import statements. By default, the import statements are sorted case-sensitively.

Not selected

Selected

from django.http import HttpResponseRedirect from django.http import cookie from django.shortcuts import render from django.urls import reverse

from django.http import cookie from django.http import HttpResponseRedirect from django.shortcuts import render from django.urls import reverse

Structure of "from" imports

Leave as is

If this checkbox is selected, the "from" imports won't be restructured.

Join imports with the same source

If this checkbox is selected, the "from" imports of the same source are combined.

Not selected

Selected

from django.http import HttpResponseRedirect from django.shortcuts import get_object_or_404, render from django.http import HttpResponse

from django.http import HttpResponseRedirect, HttpResponse from django.shortcuts import get_object_or_404, render

Always split imports

If this checkbox is selected, the "from" imports are always placed separately.

Not selected

Selected

from django.http import HttpResponseRedirect from django.shortcuts import get_object_or_404, render from django.http import HttpResponse

from django.http import HttpResponse from django.http import HttpResponseRedirect from django.shortcuts import get_object_or_404 from django.shortcuts import render

Item

Description

Dict alignment

From the drop-down list, select the type of dict alignment:

  • Do not align: the dict's elements in sequential lines will be not aligned.

  • Align on colon: the dict's elements in sequential lines will be aligned against the colon.

  • Align on value: the dict's elements in sequential lines will be aligned against the value.

Add line feed at the end of file

Select this checkbox to add line feed character at the end of file.

Use continuation indent for

Select the Method call argument checkbox to use continuation indent for list of arguments and the Collections and comprehensions checkbox for multi-line collection literals and comprehensions. The value of the continuation indent is defined in the Tabs and Indents tab. If these checkboxes are not selected, then the indent value is used.
