bookChallenge: Automated Invoice Generator

In your freelance work, automating repetitive tasks like invoice generation can save you valuable time and ensure professionalism. Imagine you have several projects completed for different clients, and you need to send out invoices detailing the work done, hours spent, rates, and total amount due. Instead of manually creating each invoice, you can write a Python script to handle this efficiently.

To tackle this challenge, you will use hardcoded data representing a list of freelance projects. Each project will have the following details: client name, project description, hours worked, and hourly rate. Your script will generate a formatted invoice for each project, including a unique invoice number, client details, project summary, total amount due, and a thank you note. This approach not only saves time but also minimizes errors that can occur with manual entry.

You will structure your script to loop through each project, calculate the total due, and print a clear and professional invoice. By using string formatting, you can ensure the output looks tidy and is easy to read, which is important when communicating with clients.

# Example list of project dictionaries projects = [ { "client_name": "Acme Corp", "project_description": "Website redesign and optimization", "hours_worked": 25, "hourly_rate": 60 }, { "client_name": "Beta LLC", "project_description": "Mobile app development - Phase 1", "hours_worked": 40, "hourly_rate": 75 }, { "client_name": "Gamma Solutions", "project_description": "Data analysis and report generation", "hours_worked": 18, "hourly_rate": 55 } ]

This script uses Python's built-in datetime module to include the current date and generate a unique invoice number for each project. Hardcoded project data makes it easy to test and modify as needed. You can adapt this structure for real-world scenarios by reading project data from a file or database in the future.

Task

Swipe to start coding

  • Define a list of at least three projects, where each project is a dictionary containing: client_name, project_description, hours_worked, and hourly_rate.
  • For each project, generate a unique invoice number (such as INV-YYYYMMDD-XXX).
  • Print a formatted invoice for each project, including: invoice number, date, client name, project description, hours worked, hourly rate, total amount due, and a thank you note.
  • Make the output clear and professional.
