Implement copying python import path from opened file

[s-kai273]

Previously, I opened an issue suggesting the implementation of a feature to copy the Python import path.
I received a positive response indicating that a PR would be welcome if I were to implement it myself.
#23450 (comment)

So, I went ahead and implemented the feature and have now created a PR.
I would greatly appreciate it if you could review it.

I'm also happy to further discuss any necessary points in detail.
Thank you very much in advance!
