Why does this (very simple piece of) code does not work?

[jblazi]

import os

L = os.listdir('.')

for x in L:
print '!'+x+'!'+x[0]
if x != 'rename.py':
y = 'Kapustin (Hamelin): '+x
os.rename(x,y)

I get

Traceback (most recent call last):
File "<stdin>", line 9, in ?
OSError: [Errno 22] Invalid argument
TIA,

jb

Works fine here (Linux). Maybe you're using a platform where you use
invalid characters for the filename?

You didn't specify your OS, version of Python, etc,
but perhaps we can guess why it doesn't work anyway.

Have you tried executing the equivalent command manually,
either from the command line or from, say, Explorer (assuming
you're on Windows)? Can you rename any file to contain
parentheses and colons on your OS? If not, there's
your answer.

Just a guess here, but is ':' a valid filename character on your OS?
Most OSes seem to have it reserved for system use. Try using a
hyphen.

You didn't say what platform you are on but if it's Windows, then
colons aren't allowed in filenames.

Yes. Now it seems, my age begins to tell, I did not used to be so dumb...
Thx.
