where would the file "apple" have to be saved?

Dietrich

Let's do this, type in the code in your IDE and save it as apple.py in your working folder, perhaps D:\Python23\Atest
[php]
# ... save this code as apple.py ...

# this function shows the result, does not return it
def PieCookingStatus(CookingTime):
if CookingTime < 30:
print "Still cooking!"
elif CookingTime <= 40:
print "Almost done!"
else:
print "Take pie out of the oven!"

# this function returns a value
def PiePercentCooked(CookingTime):
return 100*CookingTime/40
[/php]
Then type in this code and save it as appletest.py in the same working folder. Now run this test program.
[php]
# ... save this code as appletest.py and run it to
# test the module apple.py ...

import apple

# check the apple pie in the oven after specified number of minutes
MinutesCooking = 45
apple.PieCookingStatus(MinutesCooking)
print "Pie is %d percent cooked." % apple.PiePercentCooked(MinutesCooking);
[/php]

i appreciate your help but i still dont understand it
probably because i never understood the "def" function

cause in the tutorial it was like:

a = 23
b = -23

def my_abs(num):
if num < 0:
num = -num
return num

if my_abs(a) == my_abs(b):
print "The absolute values of", a,"and",b,"are equal"
else:
print "The absolute values of a and b are different"


i understood what the program did
i just never understood what the define function did

def is not a function, it is a keyword that tells you that what follows is the name of a function and its list of arguments in ()
[php]
# the function my_abs takes the argument num, processes it and returns the result
def my_abs(num):
if num < 0:
num = -num
return num

# you call it like this
x = my_abs(-99)
# the result would be x = 99
[/php]
