What's the difference between lists enclosed by square brackets and parentheses in Python?
...es.
A list is mutable, meaning you can change its contents:
>>> m>x m> = [1,2]
>>> m>x m>.append(3)
>>> m>x m>
[1, 2, 3]
while tuples are not:
>>> m>x m> = (1,2)
>>> m>x m>
(1, 2)
>>> m>x m>.append(3)

How to “properly” print a list?
...
In Python 2:
mylist = ['m>x m>', 3, 'b']
print '[%s]' % ', '.join(map(str, mylist))
In Python 3 (where print is a builtin function and not a syntam>x m> feature anymore):
mylist = ['m>x m>', 3, 'b']
print('[%s]' % ', '.join(map(str, mylist)))
Both return:
[m>x m>...

Random / noise functions for GLSL
As the GPU driver vendors don't usually bother to implement noisem>X m> in GLSL, I'm looking for a "graphics randomization swiss army knife" utility function set, preferably optimised to use within GPU shaders. I prefer GLSL, but code any language will do for me, I'm ok with translating it on my own ...
Test if lists share any items in python
... Python, searching them is O(1) (see here for more information about complem>x m>ity of operators in Python). Theoretically, this is O(n+m) on average for n and m objects in lists a and b. But 1) it must first create sets out of the lists, which can take a non-negligible amount of time, and 2) it suppose...

Math - mapping numbers

If your number m>X m> falls between A and B, and you would like Y to fall between C and D, you can apply the following linear transform:
Y = (m>X m>-A)/(B-A) * (D-C) + C
That should give you what you want, although your question is a little ambigu...

You need to find the indem>x m> of the quantile values to get the actual (m>x m>,y) pairs.
