[FIXED] IndentationError in the Following Python Script

Issue

I have this code:

def revisedRussianRoulette(doors):
    counter = 0
    for i in range(0, len(doors), 2):
        i = int(i)
        if doors[i] == 1 & counter == 0:
            counter += 1
        elif doors[i] == 1 & counter == 1:
            doors[i] = 0
            doors[i-2] = 0
            doors[i+2] = 0
        elif doors[i] == 0 & counter == 1:
            doors[i-2] = 0
    return doors


n = int(input().strip())
doors = list(map(int, input().strip().split(' ')))
result = revisedRussianRoulette(doors)
print (" ".join(map(str, result)))

I think it should be properly indented, but I get an error that says:

C:\Users\lenovo\Desktop\Practice Files>2nd_answer_week_of_code_36.py
  File "C:\Users\lenovo\Desktop\PracticeFiles\2nd_answer_week_of_code_36.py", line 13
return doors
           ^
IndentationError: unindent does not match any outer indentation level

What is wrong, and how do I fix it?

Solution

Do indenation like this :

def revisedRussianRoulette(doors):
    counter = 0
    for i in range(0, len(doors), 2):
        i = int(i)
        if doors[i] == 1 & counter == 0:
            counter += 1
        elif doors[i] == 1 & counter == 1:
            doors[i] = 0
            doors[i-2] = 0
            doors[i+2] = 0
        elif doors[i] == 0 & counter == 1:
            doors[i-2] = 0
    return doors
