F-strings, introduced in Python 3.6, provide a concise and readable way to embed expressions inside string literals. One powerful feature of f-strings is the ability to control the alignment of the embedded values within the resulting string. This tutorial will guide you through the basics of aligning values using f-strings in Python, with code examples for better understanding.
Before diving into alignment, let's review the basic syntax of f-strings:
Now, let's move on to alignment.
F-strings provide two alignment options: left alignment () and right alignment (). These options allow you to control the placement of the embedded expression within the resulting string.
To left-align a value within a specified width, use the character followed by the desired width. Here's an example:
In this example, the name variable is left-aligned within a width of 10 characters.
To right-align a value within a specified width, use the character followed by the desired width. Here's an example:
In this example, the age variable is right-aligned within a width of 5 characters.
You can combine alignment and expression formatting within the same f-string. Here's an example that demonstrates both left and right alignment:
In this example, the name variable is left-aligned within a width of 10 characters, and the age variable is right-aligned within a width of 5 characters.
