Sorry, This is my first time using the os commands in python, Ok,
firstly, I entered "C:\" inside raw_input and stored it inside
fileroot. When i print repr(fileroot), my result was '"C:\\"' . And
when I run os.listdir with fileroot, I got that error. I typed my
os.listdir code like this: os.listdir(fileroot)

I attached my code for reference, thanks again!


import os, glob

def fileDirectory():
    # Ask user for file directory input
    fileroot = raw_input("Input")
    print repr(fileroot)


    #Returns a list with all the files inside the file root
directory( The error occurs here )
    os.listdir(fileroot)


fileDirectory()
