(To be fair, in my experience, lots of python users have no idea what a debugger is...)
I don't have anything against debuggers, but I feel more natural to write into the code and this simplifies it.
TBH I haven't tried this or snoop heavily and the project was more of a curiosity of how the internals of python work after I found a relevant SO post.
Honestly I was surprised how easy it was.
If you actually want to use something like this use snoop: https://pypi.org/project/snoop/ it is more feature rich and maintained.
