python function return values must be stored in variables

in python, when a function returns a value, it's important to store that value in a variable if you intend to use it later in your program. this tutorial will explain why this is necessary and provide code examples to illustrate the concept.
when a function returns a value in python, that value is typically produced as a result of some computation or operation within the function. if you don't store this returned value in a variable, you won't be able to access or use it elsewhere in your program. storing return values in variables allows you to manipulate or utilize the results as needed.
let's consider a simple function add_numbers() that takes two arguments and returns their sum.
if you call this function without storing the return value in a variable, the result will be lost:
in the above code, the result of adding 3 and 5 is 8, but since the return value is not stored in a variable, you can't access or use this result further in your program.
to ensure that you can use the return value of a function, store it in a variable:
now, the result of adding 3 and 5 is stored in the variable result, allowing you to use it later in your program.
consider a function get_max() that returns the maximum value from a list:
if you don't store the return value in a variable, you can't use it:
to use the maximum value returned by get_max(), store it in a variable:
now, the maximum value from the list [4, 7, 2, 9] is stored in the variable maximum, allowing you to access and use it as needed.
storing return values from functions in variables is crucial for utilizing the results of computations within your python programs. failure to do so may lead to loss of data and prevent you from performing subsequent operations on the returned values. always remember to store return values in variables for effective programming in python.
