For this program you will complete a "rectangle simulator" program that uses four functions you will write. The full program has been written below - all you need to do is successfully write the four functions described here. Refer to the IPO notation below when writing these functions (note: you can just copy the IPO directly into your code to document your functions): I function: # input: compute_area_of_rectangle length (integer) and width (integer) # processing: computes the area of the described rectangle # output: described rectangle (integer) returns the area of the # function: # input: compute perimeter_of_rectangle length (integer) and width (integer) # processing: computes the perimeter of the described rectangle returns the perimeter of the # output: described rectangle (integer) * function: draw_rectangle length (integer) and width # input: (integer) * processing: constructs the rectangle using a series of "*" characters (see below for a sample 4 by 3 rectangle:) *** * output: This next function is used to encapsulate an input validation loop -- so you can get input and validate it all in one function call. returns the rectangle (string) # function: # input: get_input a prompt to ask the user (String), a low value (integer) and a high value (integer) * processing: continually prompts the user for input, using the supplied prompt. if the user does not enter an integer within the defined range the function will re-prompt them i output: returns the integer the user supplied (int) Here is the code for the main body of your program. Once you've writtenthe above functions, paste this code into your Python file and the program should run using your functions. length = get_input ("Enter a length between 3 and 10", 3, 10) - get_input ("Enter a width between 3 and 10", 3, 10) width = compute_area_of_rectangle (length, width) area perim = compute_perimeter_of_rectangle (length, width) print ("Area:", area, "; Perim:", perim) rect = draw_rectangle (length, width) print (rect) Note: Take a careful look at the IPO specification for the draw_rectangle function. It is supposed to return a string, which is the "image" of the rectangle. You're not supposed to print within the function -- instead you should return the fully composed string so the calling code can print it. This is going to be true for almost all functions I specify in this course, and is generally how you will use functions in programming. Almost always, you'll have functions that put together the information for output, and you will do the actual output somewhere else in the program.

Question
Transcribed Image Text:For this program you will complete a
"rectangle simulator" program that uses four
functions you will write. The full program
has been written below - all you need to do
is successfully write the four functions
described here. Refer to the IPO notation
below when writing these functions (note: you
can just copy the IPO directly into your code
to document your functions):
* function:
# input:
compute_area_of_rectangle
length (integer) and width
(integer)
# processing: computes the area of the
described rectangle
# output:
described rectangle (integer)
returns the area of the
# function:
# input:
compute perimeter_of_rectangle
length (integer) and width
(integer)
# processing: computes the perimeter of the
described rectangle
# output:
returns the perimeter of the
described rectangle (integer)
# function:
draw_rectangle
length (integer) and width
# input:
(integer)
# processing: constructs the rectangle using
a series of "*" characters (see below for a
sample 4 by 3 rectangle:)
***
***
# output:
This next function is used to encapsulate an
input validation loop -- so you can get input
and validate it all in one function call.
returns the rectangle (string)
# function:
get_input
# input:
(String), a low value (integer) and a high
a prompt to ask the user
value (integer)
# processing: continually prompts the user
for input, using the supplied prompt.
if the
user does
not enter an integer within
the defined range the function will re-prompt
them
# output:
returns the integer the user
supplied (int)
Here is the code for the main body of your
program, Once you've written the above
functions, paste this code into your Python
file and the program should run using your
functions.
length = get_input ("Enter a length between 3
and 10", 3, 10)
= get_input("Enter a width between 3
and 10", 3, 10)
width
= compute_area_of_rectangle (length,
width)
area
perim =
compute_perimeter_of_rectangle (length, width)
print ("Area:", area, "; Perim:", perim)
rect = draw_rectangle (1ength, width)
print (rect)
Note: Take a careful look at the IPO
specification for the draw_rectangle
function. It is supposed to return a string,
which is the "image" of the rectangle. You're
not supposed to print within the function --
instead you should return the fully composed
string so the calling code can print it. This
is going to be true for almost all functions
I specify in this course, and is generally
how you will use functions in programming.
Almost always, you'll have functions that put
together the information for output, and you
will do the actual output somewhere else in
the program.
