First of all, make sure that git is installed on your computer and has been configured and the public key has been set in the remote warehouse. The remote git repository I use is gitee (code cloud).
1. Create a git remote warehouse and associate it locally
Create a git remote warehouse
After clicking Create, a secret key will be generated for local connection 
to clone the warehouse to the local, which also realizes the association between the remote and the local. The command git clone [SSH of the remote warehouse] is used to 
clone the files and the remote git library The same as the file (this .git is a hidden file)
2. Create a new python project
Let's create a few files at will
At this time, our project is not abnormal, and the following operations will make changes
3. Copy the cloned file to the python project
At this time we return to pycharm, some icons have changed
At this time, the red file indicates that it has not been submitted
4. Submit the project
There are two methods to submit the project. It is recommended to use method 2:
Method 1:

and select all the files. The √ on the right can be canceled. Fill in the submission comments below and click Submit.
Method 2:
Just use the command method, you can use the command in the Terminal in pycharm to submit
and check the file status, indicating that it has entered the cache.
After the submission, the project file turns green and
then submitted to the local git warehouse
and then submitted to the remote, so that Entered our remote git warehouse 
to view the information of the remote git warehouse
Even if the above is that Pycharm is associated with remote Git
Let's add the use of .gitignore files
What is written on this file is to explain what files to upload when uploading, or what files to ignore and not to upload
After editing the .gitignore file, remember to submit it, don’t forget this!
