Python TypeError: string should be encoded without NULL bytes, not str

Question

Trying to get to know the python standard library and make some of them using my Windows machine. Using python 2.7 I have the following small script that is designed to search the directory and rename all the files in it after removing the digits from the file name. I get a typeerror that says: "the string should be encoded without NULL bytes, not str"

it calls lines 5 and 18, indicated below , where im uses 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 only backslash problem. I thought os.path.normpath would format the path as os required.

Answer 2

"... Photos \ Modified \ 0-PyTest"

Takes \ 0 as a null character. You must exit \ with \\ or simply put r in front of the line to make it raw:

 r'C:\Users\me\Photo Projects\Project Name\Project Photos\Modified\0-PyTest' 

Answer 3

If you specify the URL of the path, just add r in front of it:

(r'E: \ Images \ 1.png ')
