String interpolation is a technique used to embed variables directly into string literals. It is a common operation in any programming language and Python provides several ways to perform string interpolation.<\/p>\n\n\n\n
In this tutorial, we will explore different methods of string interpolation in Python and their advantages and disadvantages. We will also discuss the best practices when it comes to string formatting and interpolation.<\/p>\n\n\n\n
String interpolation is a feature in computer programming that allows values to be inserted into a string literal. It is a way to create a new string by embedding values, such as variables or expressions, within a string literal. String interpolation is also sometimes referred to as string substitution or variable substitution.<\/p>\n\n\n\n
In programming languages that support string interpolation, the syntax for inserting values into a string is usually a special character or sequence of characters that represents the value being inserted.<\/p>\n\n\n\n
Let’s discuss a few of the older methods used in Python for string interpolation, all of these still work just fine, but they are not the new f-string literal methods that we suggest you use. We’ll still cover them here so you can understand how they work in case you see them again.<\/p>\n\n\n\n
String Formatting with % Operator<\/p>\n\n\n\n
The % operator is one of the oldest methods of string formatting in Python. It works by using a format string that contains placeholders for variables, followed by a tuple of values that are mapped to those placeholders.<\/p>\n\n\n\n
Let’s look at an example:<\/p>\n\n\n\n
