Unfortunately there are also many opportunities for subtle errors:

>>> re.compile("(.exe)$").sub("", "abcexe")
'ab'
>>> re.compile(r"(\.exe)$").sub("", "abcexe")
'abcexe'
>>> re.compile(r"(\.exe)$").sub("", "abc.exe")
'abc'

A dot normally matches any character except newline, so you have to escape
it.
