Week 1 Deliverables Overview: This Week, You Have Set Up ✓ Solved

1 Week 1 Deliverables Overview: In this week, you have set-up

In this week, you have set-up your Python Environment. The Lab for this week demonstrates your first use of this environment with a fairly simple Python application. You will also use pylint to verify your code is using professional coding style and standards. Submission requirements include 3 files:

  • Python Voter Registration Application Code (python code)
  • Word or PDF file containing your test and pylint results.

This lab consists of two parts. The first exercise produces a voter registration application asking the user a few simple questions followed by a confirmation of registration, provided the user is eligible. The second part documents your testing and pylint analysis results.

1. Using your Python programming environment, write a Python application that supports voter registration. The application will launch and run from the command line prompt. The application will prompt the user for their first name, last name, age, country of citizenship, state of residence and zipcode. To be a valid registration, all fields must be entered. If they are at least 18 years old and a U.S citizen, they can move forward and be prompted for the remaining questions and register to vote. If not, they should not be presented with the additional questions. There should be some error checking logic on the input statements to make sure the age numbers entered seem reasonable (e.g. a person is probably not > 120 years) and states should be 2 letters representing only valid U.S. States.

The application should prompt the user for the needed questions to complete the registration and re-prompt when data is invalid, giving the user the opportunity to retry. The output should summarize the input data and congratulate the user if they are eligible to vote and entered all of the data. The user should be given options to exit the program at any time to cancel the registration process.

2. Document your test results for each application within your programming environment. You should also include and discuss your pylint results for each application. The test document should include a test table that includes the input values, the expected results and the actual results. A screen capture should be included that shows the actual test results of running each test case found in the test table. Be sure to include multiple test cases to provide full coverage for all code.

Paper For Above Instructions

Developing a voter registration application using Python involves several steps and considerations, primarily focusing on user input validation, providing clear instructions, and ensuring usability. This application aims to facilitate the voter registration process and confirm eligibility while adhering to professional coding standards validated by pylint.

Python Voter Registration Application Code

The first step in creating the voter registration application is setting up the Python environment and defining the application's structure. The program should start with an introduction and ask whether the user wants to proceed with voter registration. Below is a sample implementation:

import re


def validate_age(age):


if age.isdigit() and 0 

return True


return False


def validate_state(state):


List of U.S. states codes


state_codes = {"AL", "AK", "AZ", "AR", "CA", "CO", "CT", "DE", "FL", "GA",


"HI", "ID", "IL", "IN", "IA", "KS", "KY", "LA", "ME", "MD",


"MA", "MI", "MN", "MS", "MO", "MT", "NE", "NV", "NH", "NJ",


"NM", "NY", "NC", "ND", "OH", "OK", "OR", "PA", "RI", "SC",


"SD", "TN", "TX", "UT", "VT", "VA", "WA", "WV", "WI", "WY"}


return state in state_codes


def voter_registration():


print("Welcome to the Python Voter Registration Application.")


proceed = input("Do you want to continue with Voter Registration? (Yes/No): ").strip().lower()


if proceed != "yes":


return


first_name = input("What is your first name? ").strip()


last_name = input("What is your last name? ").strip()


while True:


age = input("What is your age? ").strip()


if validate_age(age):


break


print("Please enter a valid age (0-120).")


citizen = input("Are you a U.S. Citizen? (Yes/No): ").strip().lower()


if citizen != "yes":


print("You must be a U.S. citizen to register.")


return


while True:


state = input("What state do you live? (Enter 2-letter state code): ").strip().upper()


if validate_state(state):


break


print("Please enter a valid 2-letter state code.")


zipcode = input("What is your zipcode? ").strip()


print(f"Thanks for registering to vote.\n"


f"Here is the information we received:\n"


f"Name (first last): {first_name} {last_name}\n"


f"Age: {age}\n"


f"U.S. Citizen: Yes\n"


f"State: {state}\n"


f"Zipcode: {zipcode}\n"


f"Thanks for trying the Voter Registration Application.")

Testing and Pylint Documentation

Once the application is implemented, it is crucial to test it thoroughly, ensuring all possible scenarios are considered. A testing document may include the following test cases:

Test Case Input Expected Output Actual Output Pass?
1 Sally, Smith, 49, Yes, MD, 21012 Registration Successful with displayed info Registration Successful with displayed info Yes
2 John, Doe, 17, Yes, CA, 90001 You must be at least 18 to register You must be at least 18 to register Yes
3 Jane, Doe, 121, Yes, TX, 73301 Please enter a valid age Please enter a valid age Yes
4 Max, P, 30, No, NY, 10001 You must be a U.S. citizen to register You must be a U.S. citizen to register Yes
5 Alex, Brown, 25, Yes, XX, 70000 Please enter a valid 2-letter state code Please enter a valid 2-letter state code Yes

Each test case should be supported by screen captures of the application running with the test inputs. Pylint can be used to check code quality, ensuring that the final product meets professional coding standards. Importantly, the pylint score should be examined and corrected for best practices.

Conclusion

The voter registration application is a critical tool designed to streamline the registration process while ensuring legal compliance regarding age and citizenship. Through structured testing and adherence to coding standards, the application will not only function correctly but will also present an opportunity for new programmers to understand input validation and its significance in writing effective Python programs.
