In Python, **arguments (also called inputs or parameters) of the function** are the inputs  that are passed to a function when it is called. They allow you to provide data or values to the function, which the function can then use to perform its operations.   **Arguments of the function can be both single values and objects (list, tuple, dictionary, custom objects, etc.)**.    
We have already used `print()` function - we have to specify string as an argument of this function. Let's look at another example:

Assume that we want to write the function that calculates the sum of two different numbers and prints the result. To do it we have to **pass these two numbers to the function**. We have to do it using  `()` brackets.

# Specify two arguments of the function
def sum_of_two_numbers(num_1, num_2):
# Use arguments to calculate sum
  result = num_1 + num_2
  print(f'Sum of two numbers is {result}')
  
sum_of_two_numbers(2, 10)

>Note
>
>You may noticed that we use letter `f` at the beginning of the string as the argument of `print()` function. Such construction is called **f-string**. In Python source code, an f-string is a literal string, prefixed with f , which contains expressions inside braces.

We have passed `num_1` and `num_2` as an arguments of the function and then used them to calculate the sum. We can set an arbitrary number of function arguments. Next, you will solve a problem with 4 function arguments.    
Now let's consider an example when we use a list as an argument of the function:

def calculate_list_sum(list):
    total = 0
    for num in list:
        total += num
    print(total)

# Example usage
my_list = [1, 2, 3, 4, 5]
calculate_list_sum(my_list)

Now we will consider what a function in Python and some basic techniques used to create functions is: what are the arguments of the function, what is the return value of the function, what is the body of the function, and how to use the function in the code.

Python is a fairly flexible language in terms of creating functions. This is especially true in setting function arguments - there are several different types of function arguments, and you can choose any of them depending on the problem you are solving. Let's now take a closer look at them.

The return value of a function is the direct result of the execution of the function, which we can use in the program. There are several types of function return values - now we will consider the most commonly used.

Now it's time to consider additional topics to help make your functions more flexible and solve more complicated tasks. You will understand recursion, lambda functions, and some basics principles of writing effective and maintainable functions.
