Python f strings embed expressions into a string literal. You can use f strings to embed variables, strings, or the results of functions into a string. An f string are prefixed with “f” at the start, before the string iitself begins. Introduced in Python 3.6, make it easier to format strings.
Do F strings work in Python?
So yes, you are right, if you want to support multiple python versions you can’t use them easily.

While Python 2 is still in use for configuration management in DevOps, Python 3 is the current standard. Python (the code, not the snake) is a popular coding language to learn for beginners.
Is F-string faster than format?
F-strings provide a way to embed expressions inside string literals for formatting. An f-string is a literal string, prefixed with ‘f’, which contains expressions inside braces. An expression is evaluated at run time, not a constant value, so f-strings are faster than \%-formatting and str.
Are F-strings the best?
In a nutshell, f-Strings provide a cleaner and easier to manage way for formatting strings. Plus, they are a lot faster. You should use them whenever possible if you have access to Python 3.6 or a newer version. Earlier versions don’t support f-Strings, unfortunately.
