[PYTHON] Watch out for randint

A note I was addicted to with Python's randint. There are random.randint and numpy.random.randint as functions that return random integers within a certain interval, but these are actually different specifications.

Take a look at the documentation. First from random.randint

randint(self, a, b) method of random.Random instance Return random integer in range [a, b], including both end points.

Then numpy.random.randint

randint(low, high=None, size=None)

Return random integers from low (inclusive) to high (exclusive).

Return random integers from the "discrete uniform" distribution in the "half-open" interval [low, high). If high is None (the default), then results are from [0, low).

In other words, random.randint (a, b) may return an integer from a to b (including b), and numpy.random.randint (a, b) may return an integer from a to b-1. There is a possibility that it will come back.

What the hell is that! confusing!

I think the latter is the more natural specification. For example, range (1,5) returns [1,2,3,4].

Then, Happy Halloween and Happy Hacking!
