Note: Negative range could be added by prepending (0>s?(s=-s,'-'):'')+ to the return expression (actually, (0>s?(s=-s,'-'):0)+ would work as well).

Simple way to create matrix of random numbers
...
You can drop the range(len()):
weights_h = [[random.random() for e in inputs[0]] for e in range(hiden_neurons)]
But really, you should probably use numpy.
In [9]: numpy.random.random((3, 3))
Out[9]:
array([[ 0.37052381, 0.03463207, 0.10...
Generate a random point within a circle (uniformly)
...dom()+random() generates radii more likely to be around 1.0 but lie in the range 0.0-2.0. When folded down they're more likely to be around 1.0 and always in the range 0.0-1.0. What's more, it's exactly the proportion needed in the first sentence of this comment. Just halving produces more numbers a...
setting y-axis limit in matplotlib
...
One thing you can do is to set your axis range by yourself by using matplotlib.pyplot.axis.
matplotlib.pyplot.axis
from matplotlib import pyplot as plt
plt.axis([0, 10, 0, 20])
0,10 is for x axis range.
0,20 is for y axis range.
or you can also use matplotlib....

...: is on CLI(Command Line Interface)
%s specifies all lines. Specifying the range as % means do substitution in the entire file. Syntax for all occurrences substitution is :%s/old-text/new-text/g
g specifies all occurrences in the line. With the g flag , you can make the whole line to be substituted...
How to test if a double is an integer
... @JoelChristophel: Yes. Not all doubles with integer values are in the range of int, or even long, so that test won't work on them.

Iterate through pairs of items in a Python list [duplicate]
...
To do that you should do:
a = [5, 7, 11, 4, 5]
for i in range(len(a)-1):
print [a[i], a[i+1]]
