It is similar to execute code on a virtual machine and on the same time visualizing the python code efficiently.
The format specifier works by first adding a colon ( :) after the variable name 2f) after the variable that we want to format. It is possible to round numbers on the fly to a specific precision, such as two decimal points as in our example by adding format specifier (. This is because the f-string functionality does the data type conversion for us.

You can include any existing variable in the text template by placing the name of the variable inside a set of curly braces. The text that you want to create and/or modify is enclosed within the quotes preceded with letter f. Image from the draft text of the Introduction to Python for Geographic Data Analysis textbook by Tenkanen et al. Let’s break the f-string down a bit to understand how it works.į-string formatting explained. So, here we have managed to combined three different data types and format the floating point value in a single line.
