What I implemented in this problem: list methods, string split, data type conversion

Here's my code:

if name == 'main': N = int(input())

list_demo = []

for i in range(N):
    ip = input()

    s = ip.split()

    if s[0]=='insert':
        index = int(s[1])
        list_demo.insert(index,int(s[2]))

    elif s[0]=='remove':
        list_demo.remove(int(s[1]))
    elif s[0]=='append':
        list_demo.append(int(s[1]))
    elif s[0]=='sort':
        list_demo.sort()
    elif s[0]=='pop':
        list_demo.pop()
    elif s[0]=='reverse':
        list_demo.reverse()
    else:
        print(list_demo)

Python Solution
This solution uses switch statements.

if __name__ == '__main__':
    N = int(input())
    l = []
    for _ in range(N):
        command = input().split(' ')
        match command[0]:
            case 'insert':
                l.insert(int(command[1]), int(command[2]))
            case 'print':
                print(l)
            case 'remove':
                l.remove(int(command[1]))
            case 'append':
                l.append(int(command[1]))
            case 'sort':
                l.sort()
            case 'pop':
                l.pop()
            case 'reverse':
                l.reverse()
