Problem with regular expression

Hello all,
I'm trying to make a regular expression that looks like the following:
p = re.compile('[A-Za-z]:\\')
if p.match(filepath): return 'pc'
It looks right to me, but whenever I run the program, it fails with the following traceback:
Traceback (innermost last):
File "C:\WINNT\Profiles\PCLAER~1\Desktop\PathTest.py", line 11, in ?
print FileUtils.GetPathPlatform(path)
File "C:\WINNT\Profiles\PCLAER~1\Desktop\FileUtils.py", line 119, in GetPathPlatform
p = re.compile('[A-Za-z]:\\')
File "d:\Python\Lib\re.py", line 79, in compile
code=pcre_compile(pattern, flags, groupindex)
pcre.error: ('\\ at end of pattern', 10)
So it looks like we can't have a backslash at the end of a pattern. Is this true? If so, how can I work around that, as any type of character can go after the backslash, except for these characters:
\ / : * ? " < > |
Any ideas? Just worth mentioning: I'm (still) using Python 1.5.2...
Thanks,
Pieter
