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
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
.Click OK.
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 for details.
PyCharm will be searching for a virtual environment in the source directory.
If no environment is detected, PyCharm will set up the system interpreter for the project:
You can click the Configure a Python Interpreter link and select Interpreter Settings to configure a Python interpreter and install packages, if needed.
With this done, you are all set to start working on your project in PyCharm: double-click your files in the Project tool window to edit them.
