This second line does nothing, since the first line always returns.
But it doesn't matter much, since you never call it. Don't you want two
functions?
def GetInt(prompt):
"""Returns a number, or None if user doesn't answer."""
while True:
said = input(input(prompt))
This has been corrected several times, by various people. What do you
think it does, and what do you wish it would do? Is there ever a reason
to call input with the results of a call to input?
if not said:
return None
try:
number = int(said)
except ValueError:
print (said, "is not a number.")
continue
return number
The return never gets executed, since it follows an unconditional
continue statement. Do you perhaps want it dedented?
def Test():
first = GetInt('Please enter inches:')
if first:
second = GetInt('Please enter cms:')
Do you always want to do a pair of conversions? if not, why are you
asking for both values before doing anything?
print(first, "*", 2.54, "=", "cms")
This prints an equation without actually printing a result.
print(second, "/", 2.54, "=", "in")
Ditto.
Test()
