In Python, function arguments are the inputs you give to a function when you call it. They let you provide data or values that the function can work with. These arguments can be individual values or objects like lists, tuples, dictionaries, or custom objects.

For instance, when we use the print() function, we provide a string as an argument. Here's 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.

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:
