Using Python’s Random Module to Generate Integers

In Python, the random module allows you to generate random integers. It’s often used when you need to a number to be picked at random or to pick a random element from a list. Using it is actually really straightforward. Let’s say you want to print a random integer within a given range, like 1-100. Here’s how […]

Using Break and Continue Statements in Python

In Python, break statements are used to exit (or “break) a conditional loop that uses “for” or “while”. After the loop ends, the code will pick up from the line immediately following the break statement. Here’s an example: even_nums = (2, 4, 6) num_sum = 0 count = 0 for x in even_nums: num_sum = […]

Quick Tip: Using Sets in Python

In Python, sets are lists that don’t contain any duplicate entries. Using the set type is a quick and easy way to make sure that a list doesn’t contain any duplicates. Here’s an example of how you would use it to check a list for duplicates: a = set([“Pizza”, “Ice Cream”, “Donuts”, “Pizza”]) print a […]
