Simplify Your Python Code with F-Strings: A Step-by-Step Tutorial | Python | Tamil

F-strings, or "formatted string literals," are a way to embed expressions inside string literals in Python. They were introduced in Python 3.6 and provide a concise and readable way to create strings that include the values of variables or the results of expressions.

Key points about f-strings:

Prefix with 'f': To create an f-string, you prefix the string with the letter 'f' or 'F'.

Curly Braces {}: Inside the f-string, you can include expressions enclosed in curly braces {}. These expressions are evaluated at runtime, and their values are inserted into the string.

Variables and Expressions: You can include variables, function calls, arithmetic operations, and other expressions inside the curly braces. Python will evaluate these expressions and replace them with their values in the resulting string.

String Formatting: You can also specify formatting options inside the curly braces to control how the values are displayed. For example, {variable:.2f} would format a floating-point number to two decimal places.

F-strings are widely used because they make it easy to create formatted strings without the need for complex concatenation or formatting functions. They improve code readability and maintainability by allowing you to directly embed values within string literals.
