title: guide to defining functions within functions in python
introduction:
in python, defining functions within other functions is a powerful technique known as nested functions. this approach allows you to encapsulate functionality within a specific scope, enhancing code readability, organization, and reusability. this tutorial will walk you through the concept of defining functions within functions, along with practical examples to illustrate its usage.
in the above example, inner_function() is defined within outer_function().
accessing nested functions:
nested functions are only accessible within the scope of their enclosing function. this means that you can't call inner_function() from outside outer_function().
example: using nested functions for calculation:
let's illustrate the concept with a simple example of calculating the area of a rectangle using nested functions.
in this example:
in this example:
conclusion:
defining functions within functions in python, also known as nested functions, is a useful technique for encapsulating functionality and improving code organization. by using nested functions, you can create modular and reusable code structures, leading to cleaner and more maintainable codebases. experiment with nested functions in your python projects to take advantage of their benefits.
