Question

Hello, I have a little problem with my code, i get the error I cant determine why:
>>> twoplusodds
[2, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99]
>>> for i in range(1,twoplusodds[-1]):
print twoplusodds[i]

3
5
7
9
11
...
...
97
99

Traceback (most recent call last):
File "", line 2, in print twoplusodds[i] IndexError: list index out of range That error should not be, and I cant spot the bug.

Answer 1

if I just write:
>>> twoplusodds[-1]
99

as you can see, it works fine. but when its in that code - it gives the :
IndexError: list index out of range

Answer 2

Your range is going from 1-98. Your has only about half of that many indices. You should do 0 (indices start at 0, not 1), len(twoplusodds) instead.

Answer 3

Alternatively, you don't even need a range, you could just do:

Answer 4

thankyou. the second choice still gave me an:
for i in twoplusodds:
TypeError: 'function' object is not iterable

as there is more to the code, which i didnt mention.
But the 1st choise, where I use "len" worked perfectly. cheers

Answer 5

This is python being a jerk. You can only name one thing twoplusodds. So you must have a function named twoplusodds that's overwriting the array value.At least this is my guess. You didn't post the code, so I can't know for sure.
