It's considered good UI design to phrase the prompt in such a way as 
to
help the user know what to input:

Thus:

>>> x = int(input("Date(1-31): "))

or

>>> s = int(input("Sex(m=1,f=2): "))

And then you have trhe responsibility to catch the error just in 
case...

This is all part of "industrial standard" programming. You have to 
make
your programs foolproof, while bearing in mind that nature keeps 
buiding
bigger and better fools!
