Real Python: A Guide to Modern Python String Formatting Tools

In Python, f-strings and the .format() method are used for string interpolation and formatting. F-strings are string literals that allow you to insert variables or expressions directly into them using a pair of curly braces. They are created by prepending an 'f' or 'F' to the literal. You can use single, double, or triple quotes to define an f-string. F-strings can be used to interpolate variables into your string, and Python treats anything outside the curly braces as a regular string. The .format() method is another way to format strings, which allows you to format the interpolated values using replacement fields. You can create custom format specifiers to format your strings. F-strings are popular in modern Python code, while the .format() method is useful for working with older versions of Python or legacy code.
