• To help us organize longer programs

Which of the following parameters is optional?

sample (a, b, c, d = 121)

• a

• d

• c

• b

Consider the following subprogram: def mult(a, b = 1, c = 1): print(a * b * c) What is output by: print(mult(3, -10))

Subprograms go __________ the main program.

• outside

• after

• inside

• above

We __________ to separate the code in subprograms from the main code.

• use indentation

• use comments

• use modules

• use variables

Answer explanation

indenting is used to make it clear what code is part of a subprogram and what is not

A __________ variable exists only inside a method and cannot be accessed in main.

• global

• local

• static

• public

Consider the following code:

def addIt (a, b):

return a + b

print (a)

What is wrong with this function?

(Ignore indentation bc Quizizz cannot format correctly)

• There should be a third parameter.

• The method cannot return a value.

• The method should only have one parameter.
