For background, please read the functions as values page.
Consider these two functions:
def add(a, b):
return a + b
def sub(a, b):
return a - b
Here’s add in action:
add(4, 1)
5
Here’s sub in action:
sub(4, 1)
3
There’s some code below, that will error, because the assignment
statement does not set func to have the value we need. Set func
correctly so the result equals 2:
func = add
func(10, 8)
18
Set my_func1 and my_func2 in the code fragment below, so that the
result is 12:
my_func1 = # Your code here
my_func2 = # Your code here
my_func1(8, 2) + my_func2(3, 3)
File "/var/folders/_7/h5j1wn6n2b5c2qwh5dtr3jlm0000gq/T/ipykernel_20822/117259866.py", line 1
my_func1 = # Your code here

Here is a function that takes three arguments. The first, called f,
should be set to a function value - that is, a value that is the
internal representation of a function. The second and third values, called x and y, should set to be number values.
def do_it(f, x, y):
return f(x, y)
Set another_func so the result returned is 4:
another_func = # Your code here
do_it(another_func, 1, 3)
File "/var/folders/_7/h5j1wn6n2b5c2qwh5dtr3jlm0000gq/T/ipykernel_20822/3126590280.py", line 1
another_func = # Your code here
