Python if statement not functioning

print ("Hello World")
    myName = input("What is your name?")
    myVar = input("Enter a number:")
    if(myName == "MZ" or myVar != 0):
        print ("MZ is great")
    elif(myName == "MV"):
        print ("MV is ok")
    else:
        print ("Hello World")

No matter what I input as name (myName) or number (myVar), it always prints - MZ is great.

Please help. Thanks
