Run and rerun applications

Last modified: 10 May 2022

With PyCharm, you can run entire applications as well as particular scripts.

PyCharm uses settings that are defined in a Run/debug configurations. All the run configurations that currently exist in a project, are available in the Select Run/Debug Configuration list.

Py run config menu

If you want to see the list of all currently running applications, select Run | Show Running List from the main menu. Refer to the View running processes section for details.

Note that after you've started a run session, the App toolwindows tool window run icon in the Run tool window and in the Run/Debug Configuration Selector toggles to Active run icon to indicate that the run process is active.

tip

You can configure some tools (for example, npm scripts) to be launched before running. In this case, PyCharm runs the tools, and after success will run the application. Otherwise, the application starts immediately.

note

If the options that launch tools before running were enabled in a Run/Debug configuration, PyCharm runs the tools, and after success will run the application. Otherwise, the program will start immediately.

Running a script

  • Choose Run | Run from the main menu or press Alt+Shift+F10, and then select the desired run/debug configuration.

    This way it's possible to run any available run/debug configuration - one has to choose the desired run/debug configuration from the popup menu that shows all the run/debug configurations, existing in a project.

You can review any output from your running applications in the Run window console. The output from each application is displayed in its own tab of the Run tool window, named after the corresponding run/debug configuration.

If you re-runan application, the new output overwrites the contents of the tab. To preserve the output of an application, even if you re-run it, pin the output tab.
