In Python, string (str) is a common data type that is present in practically every code project. This is why it’s important to know how to format strings properly, such as how to execute code inside a string. Even though string formatting is not hard, there are painfully many ways to do it. This is […]

In Python, you can turn your for loops into one-liners by using comprehensions. This is a comprehensive guide to comprehensions in Python. Python supports 4 types of comprehension: By the way, there are no tuple comprehensions in Python. But you can find a way to mimic tuple comprehensions to get a very similar outcome. You will learn how

To reverse a string in Python, you can use negative slicing as follows: For example, let’s reverse a string “Testing”: Output: To learn more approaches to reverse a string in Python, feel free to read along. You’ll also better understand how the above example really works. If you want to have a quick look, please

In Python, you can find the absolute value of a number with the built-in abs() function. For example, let’s figure out the absolute value of the number -10: Output: This is a quick but comprehensive guide to finding absolute values in Python. This guide teaches you what is an absolute value and how to find

An odd number is a number you cannot divide into two equal parts. An even number is a number you can evenly divide into two parts. In Python, you can use the modulo operator (%) to check if a number is odd or even. For example: This guide teaches you how to check if a

To write a Python program that converts between Celcius and Fahrenheit, you need to implement these formulas in your code: Quick Solution: Celcius to Fahrenheit Program Here’s an example program that asks for temperature in Celcius and converts the input to Fahrenheit: Quick Solution: Fahrenheit to Celcius Program And here’s an example program that asks

This is a comprehensive guide to concatenating strings in Python. This guide demonstrates 7 ways in which you can combine strings. Besides, you’ll learn what approaches are great and what is not so great. Here’s a short overview of the different approaches: The + operator The += operator The String.join() method The old % formatter

One of the main benefits of writing computer programs is to automate tasks based on inputs and conditions. Adding logic to code is possible through decision-making if…else statements. For example, a square root function should only compute the square root of an input if its value is positive. Otherwise, the function should warn about false

In Python, you can introduce logic to your code with if-else statements. You can use if-else statements to build decision-making capabilities for your program. For example: When you run this piece of code, it tells whether or not you can drive based on your age. Because the age is 10, the program tells you cannot

Python switch-case statements are here as of Python 3.10! These statements are actually called match-case statements. With a match-case statement, you can get rid of rather verbose if-elif-else chains like this: Instead, you can use a compact match-case expression to do the exact same: In some situations, the latter approach is better. It can make
