Which of the following is a way to define and use functions in your programs?

• Using default values

• Using named arguments

• Using local variables

• Using global variables

Which of the following is a step in using your own modules?

• Create the module

• Document the module

• Import the module

• All of the above

Which module should be imported to use random functionalities in Python?

• math

• random

• os

• sys

Use a hierarchy chart or outline to plan the functions of a program.

• To organize the program structure

• To execute the program

• To debug the program

• To compile the program

In general terms, describe how to define a function, including the use of a return statement.

• A function is defined using a specific syntax and may include a return statement to output a value.

• A function is defined by listing all variables and does not use a return statement.

• A function is defined by writing a paragraph describing its purpose.

• A function is defined by using a loop and a return statement is optional.

In general terms, how do you call a function?

• By specifying the function name followed by parentheses.

• By writing the function definition again.

• By using a loop to iterate over the function.

• By declaring the function as a variable.

In general terms, describe how to define and call a main() function.

• Define the main() function using the 'def' keyword and call it using 'main()'.

• Use the 'function' keyword to define main() and call it with 'execute main'.

• Declare main() with 'start' and invoke it with 'run main'.

• Define main() with 'create' and call it using 'invoke main'.

Describe the use of default values in a function definition and in the statements that call the function.

• Default values allow functions to be called with fewer arguments than defined.

• Default values are mandatory for all function parameters.

• Default values can only be used in the function call, not in the definition.

• Default values must be the same for all function calls.

Describe the use of named arguments in calling statements.

• Named arguments allow you to specify the name of the parameter in the function call.

• Named arguments are used to define the function itself.

• Named arguments are only used in anonymous functions.

• Named arguments are a type of loop structure.

Which of the following best describes the recommended use of global variables, local variables, and global constants?

• Global variables should be used extensively for all data storage.

• Local variables should be used within functions to limit scope.

• Global constants should be frequently changed to adapt to new requirements.

• Local variables should be avoided to ensure data is accessible everywhere.
