Hello again
Hope you are all well.
I'm trying to make a "match 3" game, where you have a square grid and
have to put 3 matching shapes in a row.
I need a function that tells me if the game is playable, ie. it is
possible to match 3 shapes by only swapping 2 adjacent shapes.

I think this is easily seen by a for loop:
for something in range(20):
print something
In the above "something" is a variable, in this case an int(which is
immutable). However, "something" is changed every time it goes through the
loop.
It's the equivalent of:
x = 0
x = 1
x = 2
and so on

I am a newbie too, but
from collections import defaultdict
Then you can do:
data = defaultdict(int)
Everything (all keys) start at 0, so you can do "+=" with no problem.
I'm sure somebody else has a better solution though!

Hi all,
I've been trying to write a programme that solves sudoku problems for a

the most pythonic way of doing some things.
I've decided to create nested lists (row order, column order and square

I apologise in advance for such a silly question. Normally, I start to write
to the list and work the answer out before sending the mail. Not this time.
I'm trying to work out which triangles contain the cartesian origin (0, 0)
and have the following:

HI Guys,
I have a small programme, called shop.py, that I wish to make into a
"frozen binary" ( I think that's right - I'm using Linux Ubuntu 9.04
and I want the programme to work on a windows computer that doesn't
have Python installed).
I used freeze.py from examples/Tools and everything seemed
e sense.
Thanks again

Hello there,
I got the following function while googling:
def totient(n):
"""calculate Euler's totient function.
If [[p_0,m_0], [p_1,m_1], ... ] is a prime factorization of 'n',
then the totient function phi(n) is given by:
(p_0 - 1)*p_0**(m_0-1) * (p_1 - 1)*p_1**(m_1-1) * .
Wow! I seem to have caused a great deal of comments!
I actually am looking to see if a number is a "perfect cube". I will try out
all the suggestions.
Thanks a lot.
Colin
P.S.
I have a small programme that changes decimal to binary (I don't know if it
can be changed to work with fractions or not),
Hi there, just a quick one.
Is there a way to obtain cube roots in python?
I have been trying:
math.pow(n,1.0/3)
This works with some, but with 64, for example I get:
>>> pow(64,1.0/3)
3.9996
However:
>>> 4**3
64
Any ideas?
Thanks
