ImportError: cannot import name 'Flask' from partially initialized module 'flask' (most likely due to a circular import) (C:\Users\Nitish Phutane\Desktop\flask.py)

though i have install flask on my system too.can someone please help me to run this code.

Answer 1

You have a circular import because your file in named flask.py. Change this to anything else and the problem will be gone.

Answer 2

I think you have created a file called flask.py, so now it is trying to import Flask module from your own file. Try renaming that file in desktop to something else and try again. It is called circular import, and you should always prevent it from happening.
