How to Create a Formatted String with Calculated Values in Python

If you've worked with JavaScript, you might be familiar with the convenience of template literals that allow you to mix strings and calculated values seamlessly. For instance, in JavaScript, you can easily include calculations in a template literal like this:

Using f-strings

Introduced in Python 3.6, f-strings offer a concise way to embed expressions inside string literals. Here’s how you can use f-strings to include calculations:

Example Code

Explanation

Defining Variables: You start by defining two variables, a and b, and assigning them numeric values.

Creating the f-string: By prefacing the string with f, Python treats any expressions inside curly braces {} as executable code. This allows you to perform calculations directly within the string.

Result: The variable text will contain the string 3 + 8 = 11, effectively combining both the numbers and the result of their addition in a clear format.

Explanation

Defining Variables: Similar to the previous example, we define two numeric variables.

{0} will be replaced by the value of a,

{1} will be replaced by the value of b,

{2} will show the result of the calculation a + b.

Result: As with the f-string approach, the text variable will hold the formatted string 3 + 8 = 11, incorporating both the variables and the computed value.
