Generate a random number from an interval in Python

Question

How to generate a random number in the interval [-0.5, 0.5] using Python random() or randrange() functions?

Answer 1

random returns a float and takes no arguments, randrange takes an upper and lower bound but takes and returns an int.

from random import randrange

print(randrange(-5, 5))

If you want floats use uniform:

from random import  uniform

uniform(-.5, .5)

Answer 2

this will do the trick random.random() - .5
