Or you can try something like:
x = r"C:\My\Doc\;D:\backup"
x = x.replace("\\", ";")
x = x.split(";")

The argument to split() is the literal string to split on, not a list of
potential splitting characters. So to split on '; ' your string would
have to be 'spam; egg; mail'.
To split on one of a list of characters you have to use a regular
expression and re.split().
In : import re
In : re.split('[; ]', "spam;egg mail")
Out: ['spam', 'egg', 'mail']
[; ] is a regular expression that means, "match either of ; or space".
