Python Functions 2

The main difference between procedures and functions is...?

• Procedures are longer and have more instructions

• Functions use parameter passing procedures don’t

• Functions are more difficult to debug

• Functions return values procedures don’t

What is the name of the parameter?

• say_my_name

• my_name

• name

• def

• There are none

What is the name of the function?

• say_my_name

• my_name

• name

• def

What is the purpose of functions with return values in Python?

• Functions with return values in Python are designed to stop the program execution.

• Functions with return values in Python are meant to return multiple values simultaneously.

• Functions with return values in Python are used for printing messages only.

• The purpose of functions with return values in Python is to calculate a result within the function and pass that result back to the calling code.

Explain the concept of functions without return values in Python.

• Void functions in Python are used to return specific results

• Void functions in Python are not used for side effects

• Void functions in Python do not have a return statement or return value specified. They are used for their side effects rather than returning a specific result.

• Void functions in Python always have a return statement

Write a Python function that takes one argument and returns its double.

• def double(num): return num * 2

• def triple(num): return num * 3

• def halve(num): return num / 2

• def square(num): return num * num

What is the correct way to define a function with three parameters in Python?

• def my_function(param1, param2, param3):

• def my_function(param1, param2):

• def my_function(param1 param2 param3):

• def my_function(param1, param2, param3, ...):

What is the significance of functions that return a single value in Python?

• Functions that return a single value in Python are only useful for complex programs

• Functions that return a single value in Python make the code less readable and harder to debug

• Functions that return a single value in Python are insignificant and should be avoided

• Functions that return a single value in Python are significant for promoting code organization, readability, reusability, testability, and debugging.

Why is it important to understand functions that return a single value in Python?

• Functions that return multiple values are more efficient.

• It allows for modular and reusable code.

• It makes the code more complex and harder to read.

• Understanding single-value functions is not important in Python.

Illustrate a situation where a function returning multiple values can be applied in Python.

• Calculate the area and perimeter of a rectangle using a function that takes the length and width as input parameters and returns both the area and perimeter values.

• Create a function that calculates the sum of two numbers and returns both the sum and product.

• Develop a function that converts a string to uppercase and lowercase and returns both versions.

• Implement a function that sorts a list of integers and returns the sorted list along with the maximum value.
