Currently I am improving my python using tasks on Codility and ran into a problem while completing the MaxCounter exercise.

This exercise gives an integer N and a list A where N is within the range [1..100,000] and each element of array A is an integer within the range [1..N 1].

N represents N counters all beginning at 0 and each element in A represents an operation on the list of counters. If A[i] <= N then the A[i]th counter is incremented 1 such that if A[i] = 1 then the 0th counter is incremented. If A[i] == N 1 then all of the counters are set the value of the current maximum.

After all actions are completed return the list of counters.

My code is as follows:

def solution(N, A):
    # write your code in Python 3.6

    counters = [0] * N


    for i in A:
        if i == N   1:
            counters = max(counters) * N
        else:
            counters[i-1]  = 1
    
    return counters


    pass

On the line "counters[i-1] = 1" I am receiving the error:

File "/tmp/solution.py", line 13, in solution counters[i-1] = 1

TypeError: 'int' object is not subscriptable

I am not sure why I am getting this error as I am not calling an integer as a list. Any insights would be greatly appreciated

CodePudding user response：

your list counters is being set to an integer by the line max(counters) * N you need to change the variable name that this line is set to.

Counters is an integer and not a list, so it is not subscriptable.
