[Tutor] lstrip removes '/' unexpectedly

Hi Tim,

Here's another example to help you see what's going on:

##########################
>>> s = '/home/test/'
>>> s1 = s.lstrip('/ehmo')
>>> s1
'test/'
##########################

Take a closer look at the documentation of lstrip, and you should see that 
what it takes in isn't treated as a prefix: rather, it'll be treated as a 
set of characters.
