Question

Trying to get familiar with python’s standard library and doing some mucking around with it on my Windows machine. Using python 2.7 I have the following little script which is intended to look in a directory and rename all of the files therein after removing numerals from the file name. I’m getting a typeerror that says “must be encoded string without NULL bytes, not str”

it calls out lines 5 and 18, noted below, where im using os.path.exists.

Any help would be greatly appreciated!

    import os, re, string, glob

    path = os.path.normpath('C:\Users\me\Photo Projects\Project Name\Project Photos\Modified\0-PyTest')

ln5:if os.path.exists(path):
        print "path exists at " + path
        for file in glob.glob(os.path.join(path, '*.jpg')):
            new_path = os.path.join(os.path.dirname(file), re.sub('\d', '', os.path.basename(file)))
line18:     if not os.path.exists(new_path):
                os.rename(file, new_path)

Answer 1

turns out to be the single backslash problem.
i thought os.path.normpath would format the path as required by the os.
