    done it using match case ot Switch statement you can call it but i have a question i was not able to change the value of cmd list like this can you guys help me with that why it cannot be done like that

    cmd[1]=int(cmd[1])

    if name == 'main':

    N = int(input())

    new_list=[]

    for _ in range(N) :    
    cmd=input().split()
    match cmd[0]:
        case "append":
           new_list.append(int(cmd[1])) 
        case "insert":
            new_list.insert(int(cmd[1]),int(cmd[2]))
        case "print":
            print(new_list)
        case "remove":
            new_list.remove(int(cmd[1]))
        case "sort":
            new_list.sort()
        case "pop":
            if new_list!=[]:
                new_list.pop()
        case "reverse":
            new_list.reverse()
