Importing Project from Existing Source Code
You can set up a project around the existing source code created externally, in other words, in another IDE or in a dedicated editor. PyCharm analyzes the code base and adds the .idea directory with settings.
Creating projects from existing source code
To create a new project from existing source code
From the main menu, choose.
In the dialog that opens, select the directory that contains the desired source code. Note that applications created externally are marked with the regular directory icon .
Specify whether you want the new project to be opened in a separate window or close the current project and reuse the existing one. See the section Opening Multiple Projects for details.
