Problem with RE matching backslash

[Ladvánszky Károly]

What is the correct way to match/search a backslash with regular
expressions?

print re.match('\\m', '\\m').group(0)  raises an error while
print re.search('\\m', '\\m').group(0) yields 'm'

print re.search('\\m', '\m').group(0) yields 'm'
print re.search('\\m', 'm').group(0) yields  'm'

Any helpful comment on this would be appreciated,
