Why does the out of range error occur?

Question

Python

import requests
def parse(list, poffsetids):
    posts = []
    for i in list:
        posts.insert(i, requests.get('https://api.vk.com/method/wall.get', params={'owner_id': list[i - 1], 'offset': poffsetids[i - 1]}))
    return posts
print(parse([-61969218, -87156278, -43528947],[54, 56, 76]))

Getting
IndexError: list index out of range
Why?

Answer 1

list = [-61969218, -87156278, -43528947]
for i in [-61969218, -87156278, -43528947]:
I think it's clear now, do enumerate(list)
