Getting Invalid Syntax error for elif statement. how to overcome this?

I'm trying to run this code but getting the error and spent all my time debugging.looking out for help

n = int(input())
if n % 2 == 1: 
 print("Weird")
elif(n%2==0) and 2<=n<=5:      
     print("Not Weird")
elif(n%2==0) and 6<=n<=20:
         print("Weird")
else:
             print(" Not Weird")
