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

When you call a function with a yield keyword, the code in the function does not run. Instead, a generator object is created. You can store the generator object to a variable. This generator object has the ability to run the code inside the function on demand. When you invoke the generator object, Python runs

A Python ternary operator makes it possible to write if-else statements as simple one-liner expressions. Here’s what the syntax of a ternary operator looks like in Python. This is a complete guide to using the ternary operator in Python. You will learn why and when you should or should not use it. The theory is

Dealing with dates and times in Python programs is common. You might need to write programs that deal with dates, times, or both. Besides, you commonly want to format these dates differently, build them from strings, and calculate time differences. In Python, you can use the built-in datetime module for time and date manipulation. This

A nested loop in Python is a loop that has loops inside it. Here’s a generic pattern: Even though there’s nothing special about nested loops, as a beginner, they might seem a bit scary or verbose. This is a comprehensive guide to nested loops in Python. Theory The term “nested” is commonly used in programming.

To access a nested dictionary in Python, apply the access operator twice (or more). For example, let’s access the name of a student data dictionary with the student ID of 123: Output: This guide teaches you how to access nested dictionaries in Python. Besides, you learn how to create a nested dictionary, access the elements,
