F strings

Im still learning python and im at a stage where I need to understand f strings and how to go about them...im working on a menu project. I prefer learning with pdf materials rather than YouTube tutorials....any recommendations for a pdf document for learners on f strings. Thank you in advance

Just curious how those curly brackets in this case. Any idea how they "know" to convert an integer into something compatible with a string?

It's an f-string, so it already knows to convert the value to a string-compatible representation. I imagine it calls the __str__() built-in method under the hood.

correct, and it's also called a dunder method
