python string formatting with variables

String formatting is a crucial aspect of programming, allowing developers to create dynamic and readable output by incorporating variables into strings. In Python, there are several ways to format strings, and understanding these methods is essential for effective coding. In this tutorial, we'll explore various string formatting techniques using variables in Python.
The % operator is a legacy method for string formatting in Python. It involves using format specifiers to indicate the type and placement of variables within the string.
In this example, %s is a placeholder for a string, and %d is a placeholder for an integer. The values are provided in a tuple after the % operator.
Here, the curly braces are placeholders that will be replaced by the variables provided in the format() method.
Introduced in Python 3.6, f-strings provide a concise and expressive way to format strings. Simply prefix the string with f and embed variables directly inside curly braces.
F-strings offer a clean syntax and automatically evaluate expressions enclosed in curly braces.
The string.Template class provides a simple template-based string formatting mechanism.
Here, placeholders are denoted by $ followed by the variable name.
Python offers multiple ways to format strings, each with its own advantages. Choose the method that best suits your coding style and the version of Python you are using. F-strings are preferred for their readability and conciseness, especially in Python 3.6 and later versions. Experiment with these techniques to become proficient in string formatting with variables in Python.
