Hey folx,
Got a weird one here. I have a little program to
grow some bananas. I have a banana class. It has
methods for maturing at specified intervals,
displaying different bitmaps at different life stages,
and spawning new plants at maturity.
The program works by creating a list of the class
instances:
bananacount = input('How many bananas do you wanna
see? ')
for x in range(0, bananacount):
banananame = "banana" + str(x)
new_banana = flora.Banana(banananame, 0, 0)
bananas.append(new_banana)
The code above creates the original list. Then when
bananas get propagated, we append to the list:
def bananaMaker(baby_x, baby_y, banana_name, bananas):
new_banana = Banana(banana_name, baby_x, baby_y)
bananas.append(new_banana)
So far, so good, right? It's easy to append to the
list. The problem comes when I try to remove items
from the list. I'm supposed to use the value of the
item I want to remove. But what is the value of a
class instance? If I create two bananas and then
print my list, I get something like this:
[<flora.banana instance at 0081168C>, <flora.banana
instance at 0081144C>]
How do I feed that into banana.remove(listitemvalue)?
Thanks in advance for your help. We're being overrun
here.
- Chris
PS - On the other hand, it's pretty cool to be able to
say that I've crashed my computer with bananas. :-)
