Python's f-strings provide a readable way to interpolate and format strings. They're readable, concise, and less prone to error than traditional string interpolation and formatting tools, such as the .format() method and the modulo operator (%). F-string
The new f-string implementation will be fully backward-compatible. All these benefits and advantages sound exciting. Are you ready to give them a try? Yes? Then keep reading. But hold on, before jumping to action, you need to install a pre-release version of Python 3.12. The 3.12.0b4 ...
