PyCharm Community includes a built-in IDE Features Trainer. It provides interactive training courses to help you learn how to do some common tasks, such as refactoring code, navigating through projects, debugging, and working with version control.
Make sure the IDE Features Trainer plugin is enabled in the Installed tab of the Plugins page in the IDE settings.
To open the Learn tool window and start your exercises, select View | Tool Windows | Learn or Help | Learn IDE Features from the main menu. The tool window lists the available tutorials.
