No, but it's pretty easy to do:

def exact_lstrip(astring, stripstring):
     if astring.startswith(stripstring):
         astring = astring[len(stripstring):]
     return astring

Maybe it's because other people would have different expectations?

The current implementation of strip() (including lstrip() and 
rstrip()) seems to work well for the most common case, and I'm not 
sure that your expectation is necessarily more generally useful than 
the current behavior.  Especially given that your behavior is the one 
that's easier to hand-code if it's desired.
