Question

This is my Code and it gives me this error message. Why?

if __name__ == '__main__':
    l=[]
    N = int(input())
    for z in range(N):
        x=input().split()
        if (x[0]=="insert"):
            l.insert(int(x[1]),int(x[2]))
        elif(x[0]=="print"):
            print(l)
        elif(x[0]=="remove"):
            l.remove(int(x[1]))
        elif (x[0]=="append"):
            l.append(x[1])
        elif(x[0]=="sort"):
            l.sort()
        elif(x[0])=="pop":
            l.pop()
        elif(x[0]=="reverse"):
            l.reverse()

Answer 1

You appended string value at x[0] == "append".

It should work when you change to l.append(int(x[1])

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