input() returns a string so the values here
should be 'boy' or 'girl' - Notice the quote signs.
op = input("How are you feeling today? ")
if (age in (1,2,3,4,5,6,7,8,9,10,11,12)):
print (name,"you are a little",gb,"that is feeling",op,"today.")
If you are using loing sequences of values you should consider using the
range() function instead or use a comparison check:
either
if age in (range(1,13): # last value not included
or
if 1 <= age <= 12:
Its less typing and easier to see the intention.
For small numbers of values the tuple approach is
fine but once you get more than say, 7 values its
harder to read.
The exception is if you are testing for non
contiguous values, in that case an explicit tuple
will be needed.
if (age in (18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33)) and (gb ==
boy):
Notice that you are testing
.... and (gb == boy):
no quotes so Python looks for a variable called boy.
if (age in (18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33)) and (gb ==
girl):
The same here for girl
(34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56))
and (gb == boy):
NameError: name 'boy' is not defined
>>>
So use quotes when testing for string values
you might also like to force the input to lowercase so that users can
type Boy or BOY if they wish:
.... (gb.lower() == 'boy')
