Python Programming

I am suppose to write a program function "removeDuplicate" that given a list removes and returns any repeated items from a list so that each item appears at most once.

- For instance, the list [1,1,2,3,4,3,0,0] would become [1,2,3,4,0].

My source code is as follows:

def removeDuplicate(lst):

lst.sort()

for i in range(len(lst)-1):

if lst[i] == lst[i+1]:

lst.pop(i)

return lst

I keep getting an "IndexError: list index out of range"

I have tried changing the range value using len(lst), len(lst)+1, len(lst)+2 and even len(lst)-2 just to see the result. But same error message keeps popping up.

Please what am I doing wrong. I would gladly appreciate if you can send me a pic of a proper run of the removeDuplicate function as well if you can.

Thanks..
