completion message that includes the user’s full name and a temporary password.
Console
Student Registration
First name: Eric
Last name: Idle
Birth year: 1934
Welcome Eric Idle!
Your registration is complete.
Your temporary password is: Eric*1934
Specifications
The user’s full name consists of the user’s first name, a space, and the user’s last name.
The temporary password consists of the user’s first name, an asterisk (*), and the user’s birth year.
Assume the user will enter valid data.
Save the file with the filename registration_XXX.py where XXX is either your initials or your last
name.
COP2002 Project 3-1: Change Calculator
Create a program that calculates the coins needed to make change for a specified
monetary amount.
Console
Change Calculator
Enter dollar amount (for example, .56, 7.85): 3.37
Quarters: 13
Dimes: 1
Nickels: 0

Continue? (y/n): n
Bye!
Specifications
• The program should display the minimum number of quarters, dimes, nickels, and pennies that
represent the coins that make up the specified amount.
• Assume that the user will enter a valid number.
• The program should continue only if the user enters “y” or “Y” to continue.
• Save the file with the filename change_XXX.py where XXX is either your initials or your last name.
COP2002 Project 4-1: Prime Number Checker
Create a program that checks whether a number is a prime number. The display
should include whether or not the number is prime and a list of the number’s factors. For
numbers that are not prime, also include the number of factors for that number.
Console
Prime Number Checker
Please enter an integer between 1 and 5,000: 7
The factors of your number are:
1
7
7 is a prime number.
Try again? (y/n): y
Please enter an integer between 1 and 5,000: 12
The factors of your number are:
1
2
3
4
6
12
12 is NOT a prime number.
It has 6 factors.
Try again? (y/n): n
Specifications
A prime number is divisible by two factors (1 and itself). For example, 7 is a prime number because it
is only divisible by 1 and 7.
If the number is prime, the program should display its factors (1 and the number itself).
If the number is not a prime number, the program should display the factors and its number of factors.
Store the code that gets a valid integer for this program in its own function.
Store the code that calculates the number of factors and displays the factors for a number in a
function.
Store the rest of the code that gets input and displays output in the main function.
Save the file with the filename primes_XXX.py where XXX is either your initials or your last name.

Specifications
For the view and del commands, display an error message if the user enters an invalid contact
number.
Use the contacts.csv file to store the data for the program.
When you start the program, it should read the contacts from the CSV file.
When you add or delete a contact, the change should be saved to the CSV file immediately. That way,
no changes are lost, even if the program crashes later.
Note: you must close the CSV file before running the program or it will not work.
Save the file with the filename contacts_XXX.py where XXX is either your initials or your last name.
COP2002 Project 8-1: Contact Manager with exception handling

When you start the program, it should read the contacts from a CSV file.
If the program can’t find the CSV file, it should display an appropriate message and create a new
CSV file that doesn’t contain any contact data.
For the view and del commands, display an appropriate error message if the user enters an invalid
integer or an invalid contact number.
When you add or delete a contact, the change should be saved to the CSV file immediately.
Save the file with the filename contacts2_XXX.py where XXX is either your initials or your last
name.
COP2002 Project 9-1: Monthly Payment Calculator
Create a program that calculates the monthly payments on a loan
Console
Monthly Payment Calculator
DATA ENTRY
Loan amount: 500000
Yearly interest rate: 5.6
Years: 30
FORMATTED RESULTS
Loan amount: $500,000.00
Yearly interest rate: 5.6%
Number of years: 30
Monthly payment: $2,870.39
Continue? (y/n): y
DATA ENTRY
Loan amount: 500000
Yearly interest rate: 4.3
Years: 30
FORMATTED RESULTS
Loan amount: $500,000.00
Yearly interest rate: 4.3%
Number of years: 30
Monthly payment: $2,474.36
Continue? (y/n): n
Specifications
The interest rate should only have one decimal place for both the calculation and the formatted
results.
The formula for calculating monthly payment is:
month_payment = loan_amount * monthly_interest_rate / (1 – 1 / (1 + monthly_interest_rate) ** months)
Use the locale module to ensure the results are formatted for the proper location.
Use the decimal module and its quantize() method for rounding.
Assume that the user will enter valid data.
Save the file with the filename month_payment_XXX.py where XXX is either your initials or your
last name.
Hint
You may find the Future Value program on pp. 264-265 of the textbook to be helpful.
COP2002 Project 10-1: Pig Latin Translator
Create a program that translates English to Pig Latin.
Console
Pig Latin Translator
Enter text: Tis but a scratch.
English: tis but a scratch
Pig Latin: istay utbay away atchscray
Continue? (y/n): y
Enter text: We are the knights who say nee!
English: we are the knights who say nee
Pig Latin: eway areway ethay ightsknay owhay aysay eenay
Continue? (y/n): n
Specifications
Convert the English to lowercase before translating.
Remove any punctuation characters before translating.
Assume that words are separated from each other by a single space.
If the word starts with a vowel, just add way to the end of the word.
If the word starts with a consonant, move all of the consonants that appear before the first vowel to
the end of the word, then add ay to the end of the word.
If a word starts with the letter y, the y should be treated as a consonant. If the y appears anywhere else
in the word, it should be treated as a vowel.
Save the file with the filename pig_latin_XXX.py where XXX is either your initials or your last
name.
Note:
There are no official rules for Pig Latin. Most people agree on how words that begin with consonants
are translated, but there are many different ways to handle words that begin with vowels.

• For the date/time of departure and arrival, the program should use the YYYY-MM-DD format for
dates and the HH:MM AM/PM format for times.
• For the miles and miles per hour, the program should only accept integer entries like 200 and 65.
• Assume that the user will enter valid data.
• Save the file with the filename arrival_XXX.py where XXX is either your initials or your last name.
Bonus: +25 points
• If you add the following to your program, your grade on this program can be as high as 125%. This
will help your overall Homework average!
• Add validation (error checking) and exception handling for all user entries. In other words, do not
assume the user will enter valid data.
• If you do this part, let me know (in the Comment area of the Drop Box) that I can enter invalid data
and the program will not crash.
