Functions

Question 1

Change the function header below to use a default parameter value of “blue” if no color is specified.

def choose_car(engine, color, model):

Answer 1

def choose_car(engine, model, color=”blue”):

Note that parameters with default values must place at the end !

Note that when typing a default parameter value, no spaces should used, i.e., color=”blue” vs colour = “blue”

Question 2

If a function has multiple “return” statements, what happens once the function hits the first return statement

Answer 2

It immediately exists the function and returns the specified value

Emphasis: it will EXIT IMMEDIATELY - it’ won’t run any more code, including other return statements!

Question 3

How do you define a variable-length argument in a function?

Answer 3

Put a “*” in front of the parameter name, e.g.,

def pizza_toppings(*ingredients):

Question 4

What is the correct order for defining the following function arguments:

a variable-length
b regular
c) default

Answer 4

a) regular
b) variable-length
c) default

When using both variable-length & default arguments together, the default arguement MUST be called by name
