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. Some examples of formatted string ...
L Specifies that a following a, A, e, E, f, F, g, or G conversion specifier applies to a long double argument. The same rules specified for fprintf apply for printf, sprintf and similar functions.
f-strings are cute, and remind me of Ruby syntax. But they don't seem to have a lot of advantages, and, as you've said, they unnecessarily break compatibility with Python < 3.6
This is called f-strings and are quite straightforward : when using an "f" in front of a string, all the variables inside curly brackets are read and replaced by their value.
A few of these don't do anything interesting, or even anything visible. I have indicated those which don't do anything visually. F3 + S - "Force Reload" - Visually, does little (lags, flickers) F3 + T - Refresh Textures - Visually, does little (lags, flickers) Shift + F3 + F - Increase Render Distance F3 + F - Decrease Render Distance F3 + A - "Load Renderers" - (essentially reloads all visual ...
Is there an easy way with Python f-strings to fix the number of digits after the decimal point? (Specifically f-strings, not other string formatting options like .format or %) For example, let's s...

Unlike f -strings, the {...} placeholders are not expressions and you can't use arbitrary Python expressions in the template. This is a good thing, you wouldn't want end-users to be able to execute arbitrary Python code in your program. See the Format String Syntax documenation for details.
The other answers are correct that Python 3.6 or later is needed for f-strings to work in standard Python. If for some reason you don't want to upgrade, though, you can run pip install future-fstrings which will allow fstrings to work on earlier versions. If you are running Python in a different environment, here's how f-strings work in various Python implementations: Nuitka supports up to ...
