Try writing the code to do what lstrip actually does
- its much harder. So the library includes the more
difficult function and lets you code the easy ones.
def lstrip(string,chars=' ')
string = list(string)
t = 0
for x in string:
if x in chars:
string.remove(t)
else:
break
t = t+1
Okay, so it's not that difficult,
Well, after fixing the obvious syntax error I tried
print lstrip('abcd', 'abcd')
and got
Traceback (most recent call last):
File "D:\Personal\Tutor\LStrip.py", line 11, in ?
print lstrip('abcd', 'abcd')
File "D:\Personal\Tutor\LStrip.py", line 6, in lstrip
string.remove(t)
ValueError: list.remove(x): x not in list
so maybe it's not that easy either. Don't forget the unit tests! :-)
