Error while using listdir in Python

Question

I\'m trying to get the list of files in a particular directory and count the number of files in the directory. I always get the following error:

WindowsError         


        

Answer 1

Checking for existence is subject to a race. Better to handle the error (beg forgiveness instead of ask permission). Plus, in Python 3 you can suppress errors. Use suppress from contextlib:

 with suppress(FileNotFoundError):
     for name in os.listdir('foo'):
         print(name)
