You are misunderstanding what the second argument to lstrip does. It is 
interpreted as a list of characters; and lstrip will remove the maximal 
prefix of the string that consists of these characters. E.g.:
 >>> 'aaabbbcccaax'.lstrip('abc')
'x'
The first character in your string that is not one of the characters 
's', 'o', 'u', 'r', 'c', 'e', or '/' is 'l', so it strips all characters 
up to that one.
