Open source PyCharm

[Ben69ben]

as long as i won't distribute my code to anyone, It will remain private

yes( well, unless someone installed spyware on your computer in order to steal your code :-))

Note that Student license of PyCharm DOES NOT allows you to distribute your code as commercial product. But it was not you asked for initially.
Under the Student license you can use software for non-commercial, educational purposes only, including conducting academic research or providing educational services;
Note that PyCharm also has free community edition as well as open-source license for core-developers of eligible open-source projects. If you are going to distribute your code I would use the community version or choose other IDE like VSCode

Thank you for your help!
