Python 3.7 to be used. Just a simple design a program that depends on its own. You should also not need to import anything. No code outside of a function!
Below is the complete program as per the requirements. It is well explained inside the code using comments.
# function will display the menu
def menu():
print('\n1. Add a number to the
list/array')
print('2. Display the mean')
print('3. Display the median')
print('4. Print the list/array to the
screen')
print('5. Print the list/array in reverse
order')
print('6. Quit')
# function adds a number to list
def add(lst):
# keep asking until user enters a valid
number
while(True):
try:
# ask and read for a number
num = int(input('Enter the number: '))
# add the number to list
lst.append(num)
# return
return
except ValueError:
# print error message to user and ask to enter again
print('Invalid Number. Try Again.')
num = int(input('Enter the number: '))
# function displays the mean
def display(lst):
# initialize total
total = 0
# iterate through each number and add to
total
for n in lst:
total += n
# calcualte mean
mean = total/len(lst)
# print the mean
print('Mean:',mean)
# function displays the median
def displayMedian(lst):
median = 0
# get sorted list
lst.sort()
# size of list
size = len(lst)
# median index
mid = int(size/2)
# if there are even numbers
if size % 2 == 0:
# calculate median by
taking average of 2 middle elements
median = (lst[mid] +
lst[mid-1])/2
else:
median =
lst[mid]
# print the median
print('Median:',median)
# function prints list to the screen
def printList(lst):
print(lst)
# function prints list in reverse order
def printReverse(lst):
# get reverse sorted list
reverse = sorted(lst, reverse=True)
# print reverse sorted list
print(reverse)
# main function
def main():
# initialize the choice
choice = 0
# declare a list
lst = []
# read menu choice
# keep asking until user enters a valid
choice
while(True):
try:
# display the menu
menu()
# ask and read for a number
choice = int(input('Enter your choice [1-6]: '))
if choice == 1:
add(lst)
elif choice == 2:
display(lst)
elif choice == 3:
displayMedian(lst)
elif choice == 4:
printList(lst)
elif choice == 5:
printReverse(lst)
elif choice == 6:
break;
else:
print('Invalid Choice. Try Again.')
except
ValueError:
# print error message to the user and ask to enter again
print('Invalid Choice. Try Again.')
# call the main function
main()

The name of the C++ file must be search.cpp Write a program that will read data from a file. The program will allow the user to specify the filename. Use a loop that will check if the file is opened correctly, otherwise display an error message and allow the user to re-enter a filename until successful. Read the values from the file and store into an integer array. The program should then prompt the user for an integer which will...
(+30) Provide a python program which will Populate an array(list) of size 25 with integers in the range -100 (negative 100) to +100 inclusive Display the array and its length (use the len function) Display the average of all the integers in the array Display the number of even integers (how many) Display the number of odd integers (how many) Display the number of integers > 0 (how many) Display the number of integers < 0 (how many) Display the...
MATLAB homework assignment (HW6), but this time using a "vectorized" approach. Write a script that prompts the user for N integers (set N-6), one at a time, using a while loop. Error-check to ensure that each number entered is an integer, displaying an error message if it is not. If it is an integer, store it in an array variable nums. Continue prompting until N integers have been successfully entered. (You may copy and paste your code from the previous...
python language Problem Description: In this program we are going to explore a list or an array of integers using Python. Your program should read a set of integers from the user and store them in a list. Read numbers from the user until the user enters 0 to quit. Then store them in a list. Your program should them compute the sum of all the numbers in the list and output to the user. You will use lists and...
extra credit 1 Write a program that will display the following menu and prompt the user for a selection: A) Add two numbers B) Subtract two numbers C) Multiply two numbers D) Divide two numbers X) Exit program The program should: display a hello message before presenting the menu accept both lower-case and upper-case selections for each of the menu choices display an error message if an invalid selection was entered (e.g. user enters E) prompt user for two numbers...
Design a calculator program that will add, subtract, multiply, or divide two numbers input by a user.Your program should contain the following:-The main menu of your program is to continue to prompt the user for an arithmetic choice until the user enters a sentinel value to quit the calculatorprogram.-When the user chooses an arithmetic operation (i.e. addition) the operation is to continue to be performed (i.e. prompting the user for each number, displayingthe result, prompting the user to add two...
C++ programming For this assignment, write a program that will act as a geometry calculator. The program will be menu-driven and should continue to execute as long as the user wants to continue. Basic Program Logic The program should start by displaying a menu similar to the following: Geometry Calculator 1. Calculate the area of a circle 2. Calculate the area of a triangle 3. Quit Enter your choice(1-3): and get the user's choice as an integer. After the choice...
Write a program in C++. You need everything everythihng given You will create a function that validates input. It should accept only non-negative integers. If the input is incorrect the function should throw an exception. The exception will not be caught in the function. You will create a function that reads in 2 integer values. One is a number that will be raised to the power of the second. So if 5 and 6 are entered the result would be...
Java programming for ticket price calculator. It should ask the user if they would like to process another ticket order. They should indicate their selection with a Y or N. If they indicate yes, then it should repeat the entire program with the exception of the welcome screen. If they indicate no, it should show the final thank you message and end the program. If they indicate an invalid answer, it should display an error and re-prompt them for a Y...
