string formatting in python is a powerful and flexible way to manipulate and display strings. the format() method and f-strings (formatted string literals) are two common techniques used for string formatting. in this tutorial, we will explore both methods with examples.
the format() method allows you to insert values into a string by specifying placeholders and providing the values separately. here's a basic example:
output:
in this example, {} acts as a placeholder for the variables name and age. the format() method replaces these placeholders with the actual values.
you can also use positional arguments to specify the order of the values:
output:
introduced in python 3.6, f-strings provide a concise and readable way to embed expressions inside string literals. here's an example:
output:
f-strings make the code more readable and eliminate the need for the format() method. you can directly include variable names or expressions inside curly braces {}.
you can control the precision and alignment of values within the formatted string. for example:
output:
in this example, :.2f specifies that the floating-point value should be formatted with two decimal places.
these are just a few examples of string formatting in python. the format() method and f-strings offer a wide range of options for creating dynamic and formatted strings based on your specific needs. experiment with different formatting options to enhance the readability and presentation of your python code.
