Answer 1

def year_check(dd,mm,yyyy):
if yyyy > 2156 or yyyy < 0:
return True
else:
return False

-logical error: replace 'False' and 'True' with each other to correct it.

-what when day is 31 ? you didn't looked into case for it ?
-what about different months having different mumbers of days?

if you made for leap year and february, you can easily make it for rest of the months(use array for simplicity).
