Formatting floats without trailing zeros
....rstrip('.')
My reasoning:
%g doesn't get rid of scientific notation.
>>> '%g' % 0.000035
'3.5e-05'
15 decimal places seems to avoid strange behavior and has plenty of precision for my needs.
>>> ('%.15f' % 1.35).rstrip('0').rstrip('.')
'1.35'
>>> ('%.16f' % 1.35).r...
deleting rows in numpy array
...(yes, it is similar to user333700's, but a little more straightforward):
>>> import numpy as np
>>> arr = np.array([[ 0.96488889, 0.73641667, 0.67521429, 0.592875, 0.53172222],

What's the function like sum() but for multiplication? product()?
...perator
def prod(iterable):
return reduce(operator.mul, iterable, 1)
>>> prod(range(1, 5))
24
Note, in Python 3, the reduce() function was moved to the functools module.

What are paramorphisms?
...
Yes, that's para. Compare with catamorphism, or foldr:
para :: (a -> [a] -> b -> b) -> b -> [a] -> b
foldr :: (a -> b -> b) -> b -> [a] -> b
para c n (x : xs) = c x xs (para c n xs)
foldr c n (x : xs) = c x (foldr c n xs)
para c n [] = n

What exactly does the .join() method do?
...of things to join with the string. A simpler example might help explain:
>>> ",".join(["a", "b", "c"])
'a,b,c'
The "," is inserted between each element of the given list. In your case, your "list" is the string representation "595", which is treated as the list ["5", "9", "5"].
It appea...
