    Hi guys, This is the solution I thought of. Here, the commands must be taken iteratively as input. for that, we can use input().split() after a for loop, where the split() command stores the command line entered as a list!

    if command is stored as list, for example, ['insert', '0'] command would mean insert operation with 0 value. so we assign the 0th position of the command line as operation. then we convert the value to integer as the value to be added to new list is a number!

    here is the code:

    Spoiler

    if __name__ == '__main__':
    N = int(input())
 
    a = list()

    for i in range(N):
        cmd = input().split()
        operation = cmd[0] 
        
        if operation=="insert":
            a.insert(int(cmd[1]), int(cmd[2]))
        elif operation=="remove":
            a.remove(int(cmd[1]))
        elif operation=="append":
            a.append(int(cmd[1]))
        elif operation=="sort":
            a.sort()
        elif operation=="pop":
            a.pop()
        elif operation=="reverse":
            a.reverse()
        elif operation=="print":
            print(a)
