(1) Was that something like
>>> [][1]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
IndexError: list index out of range
? Please always copy and paste the traceback, don't rephrase.
(2) Show us the code that caused the error. If you provide some context it
is easier for us to identify your problem. But if I were to guess: are you
coming from a language where lists grow automatically? In Python they don't.
Instead of
mylist = []
for i in range(3):
mylist[i] = 42 # WRONG, raises IndexError
you usually write
mylist = []
for i in range(3):
mylist.append(42)
though in this particular case
mylist = [42] * 3
would work, too.
