6 Tricks to Make Python F-strings More Functional and Write Fancy Print Statements
6 tricks to manipulate the variables and thus, make f-strings more functional.
String interpolation is a way to customize strings by integrating variables into them. It allows for generating more functional strings.
One of the commonly used string interpolation methods in Python, introduced in version 3.6, is formatted string literals, also known as f-strings. The definition in the documentation is as follows:
“A formatted string literal or f-string is a string literal that is prefixed with 'f' or 'F'. These strings may contain replacement fields, which are expressions delimited by curly braces {}. While other string literals always have a constant value, formatted strings are really expressions evaluated at run time.”
Let’s do a quick example to demonstrate how f-strings are created.
F-strings are able to do much more than just replace a placeholder in a string. They also allow for manipulating and formatting the variables used in them. In this article, we will see 6 tricks that can be used to manipulate the variables and thus, make f-strings more functional.

1. Percentage
Let’s say we have a decimal point number but want to represent it as a percentage. This conversion can be done in an f-string as follows:
As we see in the example above, we can even adjust the precision using an integer along with the percentage sign.
