REST APIs with Flask and Python - Function Arguments and Parameters

This video tutorial explains function arguments and parameters in Python. It covers how to define functions with parameters, the difference between positional and keyword arguments, and the benefits of using keyword arguments. Examples are provided to illustrate functions with and without parameters, and the importance of argument positioning is discussed. The tutorial concludes with recommendations for using keyword arguments to enhance code readability.

What is the primary purpose of function parameters?

• To define the function's name

• To determine the function's return type

• To provide data for the function to operate on

• To store the function's output

In the context of functions, what is the difference between parameters and arguments?

• Parameters are used only in built-in functions, while arguments are used in user-defined functions.

• Parameters and arguments are the same thing.

• Parameters are the variables inside the function, while arguments are the values passed to the function.

• Parameters are the values passed to a function, while arguments are the variables inside the function.

What happens if you call a function without providing the required arguments?

• An error will occur indicating missing arguments.

• The function will return None.

• The function will ignore the missing arguments and proceed.

• The function will execute with default values.

Why are some arguments called 'positional arguments'?

• Because they are always optional.

• Because their position in the function call determines which parameter they correspond to.

• Because they can be used in any order.

• Because they are always required.

What is a key advantage of using keyword arguments in Python?

• They allow functions to run faster.

• They are required for all functions.

• They eliminate the need for positional arguments.

• They make it easier to understand which argument corresponds to which parameter.

What is the rule regarding the order of positional and keyword arguments in a function call?

• Keyword arguments must come before positional arguments.

• Positional arguments must come before keyword arguments.

• They must be interleaved.

• There is no specific order required.

When is it recommended to use keyword arguments?

• When the function is a built-in Python function.

• When the function has only one parameter.

• When the function has multiple parameters and it's not clear what each argument represents.

• When the function is very simple and obvious.
