Question

build a phone number from digits entered by your user. Your program will loop until 10 valid digits have been entered. It will then use those digits to display the phone number entered using the format: XXXXXXXXXX (or (XXX) XXX – XXXX for extra credit). The program will ask for a digit, it will check to see if the digit is actually between 0 and 9 inclusively. If so, the digit will be stored as the next number in the phone number. Once all digits are entered, the program will display the phone number. Hint: Remember that str(num) will convert any num into a string. Here is a typical program run. The sample user input is shown in blue italics.

Input: Enter a digit: 1 Enter a digit: 4 Enter a digit: 11 Enter a digit: 2 Enter a digit: 0 Enter a digit: 21 Enter a digit: 7 Enter a digit: 9 Enter a digit: 1 Enter a digit: 0 Enter a digit: 5 Enter a digit: 4 Output: 1420791054 (or (142) 079 - 1054 for extra credit) Before beginning this project, you will document your algorithm as a list of steps to take you from your inputs to your outputs. Each step will be added as a comment block within your code. You will have the comment block right above the code that performs the actions specified. 2 For example, before your lines of code that ask the user for inputs, you would have a comment block that states what inputs you are requesting from the user.

Please see the example code provided as a sample of this. This and all program files in this course must include a comment block at the beginning (top) of the source code file that contains:

• your name

• the Python program name

• project description

• the date

The comment lines should look like this:

#############################################################################

Your name #

Python program name #

Project description #

The date

Answer 1

CODE IN PYTHON:

#declaring and initializing the count variable to count the valid digits
count = 0
#declaring phoneNumber variable with empty string
phoneNumber = ""
while(count<10):
#taking digit as input from the user
digit = input("Enter a digit:")
num = (int)(digit)
#checking the digit
if(num>=0 and num<=9):
phoneNumber += digit
count += 1
#displaying the final output
print("The Phone number is :",phoneNumber)

OUTPUT:
