Summary: in this tutorial, you’ll learn about Python F-strings and how to use them to format strings and make your code more readable. Introduction to the Python F-strings Python 3.6 introduced the f-strings that allow you to format text strings faster and more elegant. The f-strings provide a way to embed format() method. For example: name = 'John' s = f'Hello, in an f-string at runtime.

In this tutorial, you’ll learn how to use Python to concatenate strings. Being able to work with strings in Python is an important skill in almost every program you’ll write. In some cases, you’ll want to display text in your program and need to ensure code readability. In other cases, you will want to aim for speed on your program and your method for concatenating strings will be different. Similarly, if your code requires backward compatibility, you’ll want to use one method over another. By the end of this tutorial, you’ll have learned: • Different ways of concatenating strings in Python • How to ensure backward compatibility in concatenating strings in Python • What the most readable method of concatenating strings is in Python Table of Contents • • • • • • • • • • • Concatenating Strings in Python: Methods Compared The table below breaks down the different methods of concatenating strings in Python. Each of the methods is covered in more detail in the sections below, as well as some methods that didn’t make the list! Method Category f-strings Most readable + operator Fastest %s operator Backward compatible * operator Best to repeat lists Different methods compared to concatenate strings Concatenating Strings in Python Using the + Operator One of the simplest and most common methods of concatenating strings in Python is to use the + operator. The way that this works is that using the + operator joins two strings together. In the case of strings, the + operator acts as ...

When you're formatting strings in Python, you're probably used to using the format() method. But in Python 3.6 and later, you can use f-Strings instead. f-Strings, also called formatted string literals, have a more succinct syntax and can be super helpful in string formatting. In this tutorial, you'll learn about f-strings in Python, and a few different ways you can use them to format strings. What are f-Strings in Python? Strings in Python are usually enclosed within double quotes ( "" ) or single quotes ( ''). To create f-strings, you only need to add an for an F before the opening quotes of your string. For example, "This" is a string whereas f"This" is an f-String. How to Print Variables using Python f-Strings When using f-Strings to display variables, you only need to specify the names of the variables inside a set of curly braces ") #Output Hello Python, tell me what I should learn. Learn Python! And that ends our tutorial on a happy note! Conclusion In this tutorial, you've learned how you can use f-Strings to: • print values of variables, • evaluate expressions, • call methods on other Python objects, and • make calls to Python functions.

Python f-strings, or formatted string literals, were introduced in Python 3.6. They’re called f-strings given that they are generated by placing an “f” in front of the quotation marks. What makes f-strings special is that they contain expressions in curly braces which are evaluated at run-time, allowing you large amounts of flexibility in how to use them! What are Python f-strings Python f-strings (formatted string literals) were introduced in Python 3.6 via How to write Python f-strings You write Python f-strings by writing two parts: f (or F) and a string (either single, double, or triple quotes). So, an f-string can look like this: fstring = f'string' Where string is replaced by the string you want to use. Displaying variables with f-strings f-strings make it incredibly easy to insert variables into your strings. By prefacing your string with an f (or F), you can include variables by name inside curly braces (') This would return: number = 2 This can be especially useful when you find yourself debugging by printing a lot of variables. Conclusion f-strings are immensely valuable tool to learn. In this post, you learned how to use f-strings, including placing expressions into them, using conditionals within them, formatting values, and using f-strings for easier debugging. I copied the below from this page. See the bottom of my Comments to see why… What’s more, is that you can even act on different variables within f-strings, meaning you can go beyond the use of constan...
