You have a literal carriage return in your command line (created by some errant editor or a Windows user or some such):

$ python nosuchfile.py
python: can't open file 'nosuchfile.py': [Errno 2] No such file or directory
$ python nosuchfile.py^M
': [Errno 2] No such file or directory

(the ^M above, I created by typing control-V control-M, where control-V is my "lnext" character).

The error message prints the file name, including the carriage return, and then the rest of the characters overwrite the initial part of the error. Note that if you make the file name just a bit longer, you'll see part of it:

$ python verylongfilenamethatdoesnotexist.py^M
': [Errno 2] No such file or directoryamethatdoesnotexist.py

To fix it, open the crontab entry/file with an editor that lets you take out that bogus carriage-return.
