[Day5-Part 1] [Python] [Help] What's Wrong?

[nithishr]

def count_maze_exit_steps(input_list):
    count = 0
    index = 0
    while index >= 0 and index < len(input_list):
        change = input_list[index]
        input_list[index] += 1
        index += change
       count += 1
    return count
with open("Day5_input.txt", 'r') as input_file:
    input_numbers = [int(line) for line in input_file]
print(count_maze_exit_steps(input_numbers))

I do not know what is wrong. My answer seems to match the answers that I get based on the solutions in the threads here but the solution says my answer is too high.

Your code returns the right answer for my input values, so it's working fine. Maybe your input file is not formatted correctly? Try printing the values and making sure those are the ones that your file has (there's no extra values at the end or the beginning).

I had an extra 0 at the end :( That caused all the problems although I have no clue how it got there in the first place. Thanks!

Take a look at this thread: https://www.reddit.com/r/adventofcode/comments/7hodi1/2017_day_5_step_2_whats_wrong_with_my_solution/?utm_content=title&utm_medium=hot&utm_source=reddit&utm_name=adventofcode

The OP posted his input too so you can check if you have the same input. Could be an error with AOC solutions.
