How can i generate all possible polynomials for coefficients of 1..10 and a degree of 10 ?
preferably in Python or ruby .
I have found PythonPoly module , but still dont understand how to make it .
Thanks .
Seems like you want somebody to do your homework for you .
But here you go ...
my_polynomials = itertools.product(range(1, 11), repeat=10)
Then :
for p in my_polynomials:
do_something_with_polynomial(p)
This is a Ruby versioin
my_polynomials = (1..10).to_a.repeated_combination(10)
To print the first 50:
my_polynomials.take(50).each{|mp| p mp}

I'm doing a Computer Science Lab with Python.
I've tried using some functions like s.insert (hot day, warm morning) but this doesn't help me add the value to the middle of the list. Can someone please help me out?
Thanks
Do this using insert
s.insert(index_to_insert, value)
For example:
s.insert(1, "hello") will insert the string "hello" as the second element of the list (since indexing starts at 0)
The problem is that you have s as a string not a list. You must convert to list then do the insertion as follows:
s = s.split()
s.insert(1, "warm")
s = ' '.join(s)

I'm trying to create in Python a regular expression that matches words that contains A-Za-z or A-Za-z0-9, but not only 0-9.
For example I want to match fooT, foo23, fo24ooo, fo4o444, but NOT 40.
Is it possible?
One way would be:
r'\w*[A-Za-z]\w*'
\w matches _ as well as 'A-Za-z0-9' - if that's wrong, write out the whole class:
r'[A-Za-z0-9]*[A-Za-z][A-Za-z0-9]*'

I have to make a regexp that matches this:
ORIGIN atcgt --(a dna sequence varying in length)-- //
But my skills aren't that good
You can use this pattern ^[ATCGU]+$
import re
dnpattern = re.compile("^[ATCGU]+$")
print dnpattern.match("ATC").group()

I am having issues selecting all of the bindpose nodes in a scene.
How can I get them?
I am using PyMEL for this particular script.
use
pm.ls( type = 'dagPose')
to get all of the pose nodes in the scene. Then loop through those and check the .bindpose attribute to see if the pose node is a dag pose.
all_poses = pm.ls(type = 'dagPose') or []
bind_poses = [k for k in all_poses if k.bindPose.get()]

Is it possible to make 2D games using python? If it is got any links to any 2D game that used Python to create it? I was thinking of learning Python but thought i should ask you guys if it can create 2D games before I do start.
Yes, check out http://pygame.org
It's a pretty popular 2D library for Python.
I use pygame myself and it is very good. It has good documentation and tutorials, and is quite well designed. I've also heard wonderful reviews of pyglet.
