Question

Write the Script in Python.

courseCategories = ["Mathematics","Computer Science","Business","Economics","Literature","Art","Music"]

'SR' - Sort a. b. 1. This operation will display the list before being sorted Display the list to the user after being sorted 2. 'CC-Character Count This operation will prompt the user for an index as an integer that will be the location to reference in the list If the integer is less than 0 or greater than the last possible index in the list, display the following error message: a. b. i. "You entered an invalid index!" If the integer is a valid index value, display the value in the list at that index along with its associated length using the following message: c. i. "The value at index <index> is <value at index> and is <length of value at index> characters long."

Sample of the output. It should look same as the output.

Answer 1

# Declare list
courseCategories = ["Mathematics", "Computer Science", "Business", "Economics", "Literature", "Art", "Music"]

# Print menu
print('*' * 24)
print('*' + "MENU".center(22, " ") + '*')
print('*' * 24)
print('*' + "SR - Sort".ljust(22, " ") + '*')
print('*' + "CC - Character Count".ljust(22, " ") + '*')
print('*' + "AS - Add String".ljust(22, " ") + '*')
print('*' * 24)
print('*' + "EX - Exit".ljust(22, " ") + '*')
print('*' * 24)

# Ask user to enter choice
choice = input('Enter your choice: ')

# Convert choice to upper() to make comparison case-insensitive
# If sr, apply sort function on list, and print it
# If cc, ask user to enter index, if index valid
# get the value from list using indexing and print result
if choice.upper() == "SR":
    print('BEFORE SORT:', courseCategories)
    courseCategories.sort()
    print('AFTER SORT:', courseCategories)
elif choice.upper() == "CC":
    index = int(input('Enter an index for the list: '))
    if index < 0 or index > len(courseCategories) - 1:
        print('You entered en invalid index!')
    else:
        value = courseCategories[index]
        print('The value at index', index, 'is', value, 'and is', len(value), 'characters long.')
else:
    print('Wrong choice entered!')
print('End of project #4')
