Hacker rank List Prepare

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()

Error Message – Traceback (most recent call last): File “/tmp/submission/20220617/03/45/hackerrank-3495035b4042c8bc0c55e799a2d2e687/code/Solution.py”, line 15, in l.sort() TypeError: ‘<‘ not supported between instances of ‘str’ and ‘int’

Answer

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

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