Example Code 
 
 
 
 
 
 
 
 
 
 
 
 
 
import random 
This must appear at 
the start of your 
program otherwise 
the random 
function will not 
work. 
num = random.random() 
Selects a random floating-point number between 0 and 1 and 
stores it in a variable called “num”. If you want to obtain a 
larger number, you can multiply it as shown below: 
import random 
num = random.random() 
num = num * 100 
print(num) 
 
num = random.randint(0,9) 
Selects a random whole number 
between 0 and 9 (inclusive). 
num1 = random.randint(0,1000) 
num2 = random.randint(0,1000) 
newrand = num1/num2 
print(newrand) 
Creates a random floating-point number by 
creating two random integers within two 
large ranges (in this case between 0 and 
1000) and dividing one by the other. 
num = random.randrange(0,100,5) 
Picks a random number between the 
numbers 0 and 100 (inclusive) in steps of five, 
i.e. it will only pick from 0, 5, 10, 15, 20, etc.
