Run and rerun applications

Last modified: 03 December 2024

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.

Select Run/Debug Configuration

If you want to see the list of all currently running applications, select Run | Show Running List from the main menu. For more information, refer to View running processes.

After you've started a run session, the Run icon in the Run widget and in the Run/Debug Configuration Selector toggles to to indicate that the run process is active and can be restarted.

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

If you re-run an 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: right-click the tab and select Pin Tab.
