Question

Objective: Work with basic input commands. Work with decision making commands. Assignment This will be done using Python. Part 1 Create a program that asks the user to input a number between 20 and 99. The program must then print out the number in English words. If the user does not enter a value between 20 and 99 display an error message stating that the input is not within a valid range. No credit will be given for programs that have a separate print statement for each value. Example: Please enter a value: 42 The number is forty two. (running the program again) Please enter a value: 30 The number is thirty. (running the program again) Please enter a value: 10 The number is not within a valid range.

Answer 1

Below is the required program. It is well explained inside the code using comments.

# read number
num = int(input('Please enter a value: '))

# check if number is invalid
# and display the error message
if num < 20 or num > 99:
    print('The number is not within a valid range.')
else:
    # declare list having english words of ones place digits
    onesName = ['','one','two','three','four','five','six','seven','eight','nine']

    # declare list having english words of tens place digits
    tensName = ['','','twenty','thirty','forty','fify','sixty','seventy','eighty','ninety']
  
    # extract both digits
    tens = int(num / 10)
    ones = int(num % 10)

    # get the corresponding words from the list, and print
    print('The number is', tensName[tens], onesName[ones])

Below is the screenshot of the program for indentation:

Below is the sample output:

This completes the requirement. Let me know if you have any questions.
