Well, with re.escape it's not messy at all :
import re
def trim_mailto(s):
regex = re.compile("^" + re.escape("mailto:";))
return regex.sub('', s)
With literally means "if you have mailto: at the beginning, replace it with
the empty string"
You could do a ltrim function in one line :
def ltrim(s, x):
return re.sub("^" + re.escape(x), '', s)
Escape will take care of escaping special characters, so the regex
escape(x) matches exactly the string "x".
