return exits the function so the second return statement never gets
executed.
def GetInt(prompt):
"""Returns a number, or None if user doesn't answer."""
while True:
said = input(input(prompt))
You are still using double input. That is almost never the
right thing to do.
if not said:
return None
try:
number = int(said)
except ValueError:
print (said, "is not a number.")
continue
return number
The continue will jump right back to the loop start so the return will
never be executed.
The only way this function will ever exit is if the user hits Enter
twice and then it will return None.
You need to rethink the logic here.
def Test():
first = GetInt('Please enter inches:')
if first:
second = GetInt('Please enter cms:')
print(first, "*", 2.54, "=", "cms")
print(second, "/", 2.54, "=", "in")
Since GetInt() can only ever return None the if will always fail and
nothing will ever be printed.
