Super Simple Python: Random Number Generator

Super Simple Python is a series dedicated to creating super simple Python projects for beginners to be able to do in under 15 minutes. In this episode, we’ll be covering building a Python random number generator in under 10 lines of code!

Video version here:

We’ll begin by importing the random module. This is a native Python library.

import random

Next, we’ll tell the user what the program does with a print statement.

print("This program generates a random number between two given numbers")

Now we’ll ask the user for the two numbers that they wish for our random number generator to generate a number between. Notice that we wrap the input in an int() statement. Input is a string by default, but we want an integer.

low = int(input("What is the lower limit? "))
high = int(input("What is the higher limit? "))

Finally, we’ll generate a number between those two numbers, low, and high using the randint function from the random library and print it out for the user to see. The f in the print statement in front of the string allows us to directly pass variables in using brackets as we do with num.

num = random.randint(low, high)
print(f"Your randomly generated number is: {num}")

When we run the final program, it should output something like the image below:
