I see many people who have their project something like this:
``` directory/ some_module.py main.py ```
and in main.py they do ``` from some_module import some_function ```
while they have a library named `some_module` that is installed from pip, and they can't figure out why Python says that there is no such function. I would recommend adding a warning like "ImportWarning: The same module exists in this folder and site-packages a well." so people won't be confused why this function doesn't exist, it happens a lot for beginners.
