What is f-string?
f-string (also called formatted string literal): A string literal prefixed with f that embeds expressions inside curly braces, which Python evaluates and inserts into the text. It supports format specifiers after a colon for width, decimals and alignment, making it the preferred way to build messages.
f-string: an example
name = 'Meera'; f'Hello {name}, total = {1234.5:.2f}' produces 'Hello Meera, total = 1234.50'.
