exception in side if clause

[sbabu]

Hi,

I am trying to raise an exception if the no is not in tuple. Where do I include the exception. Tried different ways. Getting indentation error if I put it before else. Now it does not go to the exception at all.

t = (2,3,4)

Ask = int(input("Enter a no:  "))

try:
    if Ask in t:
       print("Valid No")
   
    else:
        print("Not valid")
        print("Enter Again:")
except ValueError as e:
    print(e)
#else:
#    print("Enter Again:")
