Attaching to Local Process

On this page:

Introduction

PyCharm makes it possible to attach to a Python process, while running a Python script launched either outside of PyCharm, or inside PyCharm, but NOT in the debug mode.

Attaching to local process

To attach to a local process, follow these general steps:

  1. Launch the process intended for debugging. You can do it from operating system or using the PyCharm terminal.
  2. To find the process to attach to, do one of the following:
    • On the main menu, choose Run | Attach to Local Process:
      /help/img/idea/attachMainMenu.png
    • On the main menu, choose Help | Find Action or press Ctrl+Shift+A. In the list of actions that appears, find the desired action by typing the first letters, and select it:
      /help/img/idea/attachFindAction.png
  3. From the list of available processes that appears, select the desired process. Simplify your search by typing the first letters of its name or PID
    /help/img/idea/py_attachToProcess.png
  4. Proceed with debugging the same way as you usually do it in PyCharm (set breakpoints, step through, pause and resume the process, evaluate expressions etc.)
  5. When finished, detach the process: select the Run | Stop or click the Stop the process button /help/img/idea/stop.gif of the Debug Tool Window .
