In the following code, what is the value of total if the function call doesn't pass any arguments?

def add_numbers(first_number = 2, second_number = 4):
total = first_number + second_number

^ *6 *$

In the following code, what is the value of total?

def add_numbers(first_number = 2, second_number = 4):
total = first_number + second_number
add_numbers(second_number = 10)

^ *12 *$

Code the first line of a function, analyze, that has a single parameter, name, with a default of "Jones".

def analyze(name = "Jones"):

def `analyze`(`name `= `"`Jones`"`)`:

Code the first line of a function, x, that has two parameters, y and z. The first parameter has no default. The second parameter has a default of 1.

def x(y, z = 1):

Rewrite this code so it's legal.

def x(y = 1, z):

def x(z, y = 1):
The problem could be the parameter order, or could be something else. Parameters with defaults must come after parameters
without defaults. Also, check your spacing.

^ *def x$z, y = 1$: *$

Code the first line of a function with one parameter whose default is a string. Make everything up.

def test(name = "Park"):

^ *def [a-zA-Z_][a-zA-Z0-9_]*$[a-zA-Z_][a-zA-Z0-9_]* = •.+•$: *$

Call this function. Don't override the defaults.

def x(y = "Bulgaria", z = 1.89):

x()

^ *x *$

Code the first line of a function. It has one parameter without a default and a second parameter whose default is an integer. Make everything up.

def product_invoice(product_name, price = 1):

^ *def [a-zA-Z_][a-zA-Z0-9_]*$[a-zA-Z_][a-zA-Z0-9_]*, [a-zA-Z_][a-zA-Z0-9_]* = -?[0-9]+$: *$

Code the first line of a function. It has three parameters. All of them have defaults. The first parameter is the name of a list. The second parameter is a string. The third parameter is an integer. Make everything up.

def find_info(lst = customer_list, status =
"premier", limit = 100):

^ *def [a-zA-Z_][a-zA-Z0-9_]*$[a-zA-Z_][a-zA-Z0-9_]* = [a-zA-Z_][a-zA-Z0-9_]*, [a-zA-Z_][a-zA-Z0-9_]* = •.+•, [a-zA-Z_][a-zA-Z0-9_]* = -?[0-9]+$: *$

Code a call to this function that makes full_name equal "Hugo Jones". Don't pass any information to the function that you don't have to pass.

def assemble_name(last_name = "Jones", first_name = "John"):
full_name = first_name + " " + last_name

assemble_name(first_name = "Hugo")

^ *assemble_name$first_name = •Hugo•$ *$

Code a function that has two parameters, both of them numbers. Assign a default value to each parameter. The function does an arithmetic operation using the two numbers and displays the result.
Call the function without passing arguments.
Click the Run button above your code. If you've coded correctly, the result of the arithmetic operation will display in the right-hand panel. (You can click Instructions at the top of the right-hand panel to see the correct code.)
