Region: IOError: [Errno 22] invalid mode ('w') or filename
Use forward slashes:
'path/regionlog.txt'Or raw strings:
r'path\regionlog.txt'Or at least escape your backslashes:
'path\\regionlog.txt'\r is a carriage return.
Another option: use os.path.join and you won't have to worry about slashes at all:
output = os.path.abspath(os.path.join('path', 'regionlog.txt'))
Additionaly, Python also gives this message when trying to open a file > 50 MB from a SharePoint shared drive.
