I am trying to write a basic program that could tell the user if the element entered by them is present in the list entered by them or not.
My code:
a=(int(x) for x in input().split())
b=input('Enter the element you want to see if is present or not')
if b in a:
   print('Yes it is present')
else:
   print('Try again')
Output: Try Again (In all the cases)
Please help me correct this code and also tell me why if b in a  doesnt work but b in a works in the Python shell. 
Thanks:)
