Python: Random Numbers

Python's default random library can be very handy when you need to create random numbers.

randint for an integer between lower and upper limits:

import random
x=random.randint(55, 555)
print(x)

Output:

477

randrange(start, stop, steps), will also give a value in the range but you can also specify a step.

import random
x=random.randrange(0, 50, 4)
print(x)

Output:

24

random() will return a float value between 0 and 1. This can also be used as a random percentage.

You can explore other methods of the random library by using dir(random) and help(random)

import random
x=random.random()
print(x)

Output:

0.30172304827477603
