Question

Note: You must write this program in Python.

General Requirements

The program should display a menu and allow the user to perform one of the following tasks.

Add an item to the list
Delete an item from the list
Print the list
Print the list in reverse
Quit the program
The program should run until the user chooses to quit. In Python, programmatically quitting the application is achieved with the exit() procedure.
You should use a List to store the items the user enters into the To Do List program
The program should use a combination of these following constructs
Reading user input
Storing information in variables
Storing information in a list
Conditional (if) statement(s)
Loop(s)
Procedure(s)
Print statements
Notes and Additional Requirements/Functionality NOT Shown in Video Sample

When you ask the user for an index number you must make sure the index is valid for the list (greater than or equal to zero and less than the number of items in the list). When adding an item to the list you must make sure that the list is not full.

Please note that to get full points for each of the program's operations (add, delete, print) that you must implement these items as procedures.

The program should be written in such a way that assumes a list can hold at least 10 items. For the midterm, many students hard coded the size of their list to hold only 2 or 3 items. For this program, assume the minimum size of a list of items will be 10 (this may or may not effect how you code this in Python, this is only a guideline).

Extra Credit
Replace Item at Index (10 pts) - Write a menu option that accepts an index number and overwrites the item at that index with a new item.

Answer 1

Note: Done accordingly. Please comment for any problem. Please Uprate. Thanks.

Code:

import sys

#show menu and take input
def showMenu():
print("1) Add Item.")
print("2) Delete item.")
print("3) Print list.")
print("4) Print in reverse order.")
print("5) Replace Element.")
print("6) Exit.")
choice=int(input("Choose :"))
return choice

#add item to list
def addItem(list,maximumSize):
if len(list)<maximumSize:
item=input("Please give item :")
list.append(item)
else:
print("List is full")

#delete item
def deleteItem(list):
item=input("Please give item :")
if item in list:
list.remove(item)
else:
print("Item does not exist")

#print list
def printList(list):
for item in list:
print(item+" ",end=' ')
print("\n")

#print in reverse
def printReverse(list):
for i in range(len(list)-1,-1,-1):
print(list[i]+" ",end=' ')
print("\n")

#replace elements
def replaceElement(list):
index=int(input("Please give index :"))
if index<0 or index>=len(list):
print("Invalid Index.")
else:
item=input("Please give value to replace")
list[index]=item

#main function
def main():
list=[]
maximumSize=20
try:
  
while True:
choice=showMenu()
if choice==1:
addItem(list,maximumSize)
elif choice==2:
deleteItem(list)
elif choice==3:
printList(list)
elif choice==4:
printReverse(list)
elif choice==5:
replaceElement(list)
elif choice==6:
sys.exit()
else:
print("Invalid choice")
except:
print("Program Ended.")
  
  
main()
