Quoting W W <[EMAIL PROTECTED]>:
The number of items I want from a list is smaller than the population
(number of items) in the list, so it should work.
In this specific case, I'm asking for one item from a five-item list.
Are you sure?
change this:
for card in random.sample(SpecialA, SA):
to this:
print "Special: ", SpecialA, "\nSA: ", SA
for card in random.sample(SpecialA, SA):
then give us the output. I'll bet that your SA value is never reset to 1.
There is a part of my front-end code that declares the SA variable as
equal to 1 for the card set in question, and feeds that into the
processing function.
Changing the block of code, as you suggest, still gets me a traceback:
Special: []
SA: 1
Traceback (most recent call last):
File "C:\Documents and Settings\Alan\My
Documents\_Alan_Programming\trunk\BoosterPackMaker\BoosterPackMaker.py", line
104, in <module>
SixList_PackChooser(C_list, UC_list, R_list, BL_list,
SpecialA_list, SpecialB_list, C, UC, R, BL, SA, SB)
File "C:\Documents and Settings\Alan\My
Documents\_Alan_Programming\trunk\BoosterPackMaker\PackGenerator.py",
line 367, in SixList_PackChooser
for card in random.sample(SpecialA, SA):
File "C:\Python25\lib\random.py", line 303, in sample
raise ValueError, "sample larger than population"
ValueError: sample larger than population
So, I'm asking my program to pick 1 item from a 0-item list. How there
are zero items in the list, I don't know. That must be the problem.
You've obviously researched enough to know this:
mylist = [1, 2, 3, 4, 5]
from random import sample
sample(mylist, 3)
[2, 1, 4]
sample(mylist, 10)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.5/random.py", line 303, in sample
raise ValueError, "sample larger than population"
ValueError: sample larger than population
Okay, asking for 3 items from a 5-item list works, and asking for 10
items from a 5-item list doesn't work. It should be trying to pick 1
item from the 5-item SpecialA list, but somehow the SpecialA list has
zero items in it.
So give the print statement before your for loop a try and see what you come
up with.
Okay, I cut'n'pasted it before the traceback message.
HTH,
Wayne
Thank you.

^ The error occurs in this function.
The program picks C number of items from C_list and displays them just fine.
The program picks UC number of items from UC_list and displays them just fine.
The program picks R number of items from R_list and displays them just fine.
The program picks BL number of items from BL_list and displays them just fine.
Looking at my user-interface/front-end, it looks like the function's
being fed proper values.
