Python In Practice - 15 Projects to Master Python - Positional and Keyword Arguments

The video tutorial covers basic Python functions, focusing on addition and subtraction operations. It explains the importance of naming functions to avoid conflicts with built-in functions. The tutorial also delves into the concept of positional and keyword arguments, demonstrating how they affect function outputs. Examples are provided to illustrate how argument order and naming can change results, emphasizing the flexibility and potential pitfalls of using different argument types.

Why is it necessary to rename the function 'sum' in Python?

• To ensure it runs faster

• To prevent conflict with Python's built-in function

• To avoid confusion with a variable

• To make the code more readable

What happens if you change the order of positional arguments in a subtraction function?

• The function will not run

• The output will remain the same

• The output will change based on the new order

• The function will throw an error

What error occurs if a positional argument is missing in a function call?

• Index error

• Missing argument error

• Type error

• Syntax error

How can you ensure that arguments are correctly assigned to parameters regardless of their order?

• By using default arguments

• By using keyword arguments

• By using global variables

• By using only positional arguments

What is a keyword argument in Python?

• An argument that is passed by reference

• An argument that is passed by value

• An argument that is specified by the parameter name

• An argument that is optional

What is the advantage of using keyword arguments?

• They simplify the function definition

• They reduce memory usage

• They allow for more flexible argument order

• They make the code run faster

What will happen if you use a wrong keyword in a function call?

• The function will ignore the keyword

• The function will use a default value

• The function will throw an error

• The function will run with incorrect output
