how to use random

Answer 1

You can generate random numbers, or random variables from an array...

import random

lst = [9,3,"a"]

print(random.randint(0,100) # Generates random integer between 0 and 100

print(random.choice(lst)) # Prints a random variable from lst

Answer 2

You would mostly use pseudo-random numbers (integers) so just import random. % or range are useful

Answer 3

Typically you will

import random

and use some of the module's methods. There's is much more than just a random integer.

random.sample is fun to pick a selection of unique elements from a list (or set). Just the rigth thing if you need to draw numbers from a lottery.

random.choice is cool to pick an element from a non-empty sequence.
