My first Python project from drafting and designing to coding and README: take in initial budgets of 6 major categories and let the user to deposit, withdraw, check current statistics and generate current plots.

• Implement a Budget class to store category’s name, balance, total amount of deposition and withdrawal by updating them with functions deposit and withdraw.
• Main:
  • 1. ask for user’s initial budget of each category (Food, Clothing, Accessory or Makeup, Entertainment, Transport, and Others) and create Budget object for each category and store them in an array
  • 2. ask for the next step user want to do by typing choice number (Deposition and Withdraw / Check Statistics / Generate Plots / Quit)
  • 3. call functions respectively and repeat to ask for next step or end the program if user choose to quit
• depositAndWithdraw function:
  • argument: an array storing all categories objects
  • 1. ask for the next step user want to do by typing choice number (Deposition / Withdrawal / Exit)
  • 2. ask for the catetegory and the amount user want to deposit or withdraw if they choose to
  • 3. repeatedly asking user untill user choose to exit
  • error handling:
    • user can only type 1 / 2 / 3 to choose from Deposition / Withdrawal / Exit
    • user can only type 1 / 2 / 3 / 4 / 5 / 6 to choose from Food / Clothing / Accessory or Makeup / Entertainment / Transportation / Others
    • user can only type in a positive number for the amount they want to deposit or withdraw
    • user can only type in a number smaller than the current balance of category they want to withdraw from
• budgetStatistics function:
  • argument: an array storing all categories objects
  • 1. print balance of each category, and calculate and print total, mean, maximum and minimum balance of all categories
  • 2. print cumulative deposition of each category, and calculate and print total, mean, maximum and minimum deposition of all categories
  • 3. print cumulative withdrawal of each category, and calculate and print total, mean, maximum and minimum withdrawal of all categories
  • 4. use tabulate module to print out the percentage of balance, deposition and withdrawal of each category out of the the overall statistics
  • error handling:
    • if total balance or deposition or withdrawal is equal to 0, then keep passing the respective zero array to tabulate
• budgetPlots function: (matplotlib)
  • argument: an array storing all categories objects
  • 1. generate a bar chart with comparison between current balance, deposition and withdrawal of each category
  • 2. generate 3 subplots in one window
    • 1st subplot: pie chart showing the percentage of balance of each category out of the the overall statistics
    • 2nd subplot: pie chart showing the percentage of deposition of each category out of the the overall statistics
    • 3rd subplot: pie chart showing the percentage of withdrawal of each category out of the the overall statistics
  • error handling:
    • if total balance or deposition or withdrawal is equal to 0, keep the respective array zero
    • if total balance or deposition or withdrawal is not equal to 100, empty plot generated for respective subplot(s)
• record.txt: (file writing)
  • at the start of the program: open a new record.txt file or overwrite if record.txt already exists
  • write in the amount and category user deposit or withdraw from, and write in the current balance of that category every time
  • at the end of the program: write in the balance summary of each category and also the overall balance

• Python 3: 3.10.1 for author
• install NumPy: pip install numpy
• install Matplotlib: pip install matplotlib
• install tabulate: pip install tabulate

• download budget_calc.py and open it in a Python IDE (Visual Studio Code for author)
• run the program and follow the instructions
