Formatted string literals are prefixed with ‘f’ and are similar to the format strings accepted by str.format(). They contain replacement fields surrounded by curly braces. The replacement fields are expressions, which are evaluated at run time, and then formatted using the format() protocol: ...
The example below demonstrates how you can include expressions directly inside an f-string. Any valid Python expression can be placed within the curly braces, allowing you to perform calculations or manipulate data inline as you format your output. main.py #!/usr/bin/python bags = 3 apples_in...
By prefixing a string with f or F, you can embed expressions within curly braces ({}), which are evaluated at runtime. This makes f-strings faster and more readable compared to older approaches like the modulo (%) operator or the string .format() method. Additionally, f-strings support...

Formatters work by putting in one or more replacement fields and placeholders defined by a pair of curly braces { } into a string and calling the str.format(). The value we wish to put into the placeholders and concatenate with the string passed as parameters into the format function. Synta...
We put the letterforFin front of a string literal and specify expressions within curly braces{}in the string. Expressions within formatted literals can directly access variables in the namespace. Which means we don’t need to pass in any arguments or worry about matching placeholders with argumen...
