really? That's just like C. I thought that it would fail because of the way
lists work. Thanks!
what way?
the first three will fail if the string is empty.
>>> ""[0]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
IndexError: string index out of range
if you may end up doing this on an empty string, use slicing instead:
>>> "hello"[:1] == "<"
False
>>> ""[:1] == "<"
False
(startswith is perhaps more convenient, but method calls are rather
expensive in Python, so if you're in a hurry, it's often better to use
operators. when in doubt, benchmark the alternatives.)
