I actually just finished it, without the extra cells. I used a combiniation
of two functions and a some exception handling to do so.

Ok so I've done a bit of work on the program and rewrote it. I tried to
take everyones advice. I've used more functions, I've made it so that it is
a list of lists each containing an integer instead of another list with a
single entry.

Welcome to the list; I think you'll enjoy Python programming, and think

I'm trying to do a little personal project to trying and gain some skills.
Im trying to do version of John conways game of life. I have a working
version of the game. Written for 3.2.2 on a mac to be accessed through
terminal.
Thanks for giving that information. Many people skip the step of
describing the environment.
Some general comments first. You've managed in the code below to avoid
many of the beginner mistakes in Python, like building a two dimensional
array by replicating one row. But you do have a few quirks, by
inspection. I've not tried to run any of the code.
The biggest one is that you have only one function. Much of this code
is very repetitive, and thus likely to have errors in some portion that
doesn't run too often. And when you fix one place, you have to check
many others to see whether it has the same problem. So factor it out
into functions according to feature. A good start is to write a
function for each line in your docstring, except for the the do-while
statement. Then when you realize the biggest function is the nextmove
one, factor that as well. Most of it is spent calculating 'surronding'.
I also found it strange that each element of the grid is itself a list,
with exactly one element (an integer 0 or 1) in it. Why not just make
it an integer ? There are a lot of places which would then change, so
probably you shouldn't do that till you've refactored things to simplify.
I'm trying to give it a number of options. it dimensions, the max
number of turns, initial set up, and boundary conditions. The dimensions
and turns were pretty easy to include. The boundary conditions more
difficult, and now I'm getting stuck on the initial set up options. I can
set it up randomly but Im having problems implementing a checker board
pattern.

jdex+=1
else:
SPACE[idex][jdex]=[1,]
jdex+=1
idex+=1
Here you have set each element of the grid to be a list containing a
tuple containing an int. To be consistent with the rest of the code as
it currently is, you should use
SPACE[idex][jdex] = [0]
or if/when you take my earlier suggestion to make it just an int,
SPACE[idex][jdex] = 0
Note, though, that you don't want to make too many changes to the logic
at the same time.

turn=0
while turnT:
Any reason not to replace those two lines and the one at the end with:
for turn in range(T):

Hello all, Im trying to learn python and programming in my free time,
and I'm trying to do a little personal project to trying and gain some
skills. Im trying to do version of John conways game of life. I have a
working version of the game. Written for 3.2.2 on a mac to be accessed
through terminal.
In addition to Dave's comments I add:
I'm trying to give it a number of options. it dimensions, the max
number of turns, initial set up, and boundary conditions.
Please explain boundary conditions
The dimensions and turns were pretty easy to include.
The boundary conditions more difficult, and now I'm getting stuck on
the initial set up options. I can set it up randomly but Im having
problems implementing a checker board pattern.
It really helps when you explain the problem. What does not work as
expected?
'''displays: the text of the game of life for a set number of X x Y
for a set of R turns.
[-][-][-][-][-]
[-][-][-][-][-]
[-][-][-][-][-]
[-][-][-][-][-]
[-][-][-][-][-]
I suggest you simplify the display by using - or x e.g.:
---xx---
---xxx--
xx--
Get X,Y,T, Initial value
Create a data space X x Y
Assign initial value
print initial value and the text' initial value'
do while turnsT:
check data space
create new data space according to rules and old data space.
replace dataspace
print data space.
print end. '''
import random
X,Y,T=0,0,0
while not 4X102:
X=int(input('How many rows? enter a integer between 5 and 101: '))
while not 4Y102:
Y=int(input('How many columns? enter a integer between 5 and 101: '))
while not 4T102:
T=int(input('How many turns? enter a integer between 5 and 101: '))
Good place for a function: (untested). Also note it's common practice to
use names starting with lower case for variables. Note how we validate
input to ensure it is integer.
def getNum(prompt, lower, upper):
while True:
n = input(prompt + enter a integer between %s and %s % (lower,
upper))
if n.isdigit():
n = int(n)
if lower = n = upper:
return n
x = getNum(How many rows?, 5, 101)
y = getNum(How many rows?, 5, 101)
t = getNum(How many rows?, 5, 101)
entry=0
while not (entry=='b' or entry=='l' or entry=='d'):
can be simplified to while entry not in ('b', 'l', 'd')
entry=input('Press b for bound dimensions, press l for live
boundry, or press d for dead boundry: ')
#while not(initial=='r' or initial=='c' or initial=='g' or initial=='e'):
#initial=input('
SPACE=[]
Note (again) it's common practice to use names starting with lower case
for variables.
These nested loops
for i in range(X):
SPACE.append([])
for j in range(Y):
SPACE[i].append([0])
can be replaced with:
space = [0]*y]*x
Assuming you decide to have each cell contain either 1 or 0.
You might also consider giving space an extra row at the top and one at
the bottom, ditto for extra columns.
That will make calculating the neighbor count a lot easier, at the cost
of maintaining the extra rows/columns.
for r in range(1,x+1):
for c in range1,(y+1):
surrounding = sum([sum(space[r+z][c-1:c+2]) for z in(-1,0,1)])
OK enough for now - there's more but I'm out of time/energy right now.

If he does NOT replace the individual cells with zeroes and ones, this is wrong. You pointed that out. But it's also wrong for the rows, as you only have one row here, duplicated x times. -- DaveA ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
