Python Basics Practice

Welcome Message and User Info

Your program should start by:

• Displaying a welcome message with the program name
• Asking for the user's name and storing it in a variable
• Greeting the user by name

# Example output:
# ================================
# Personal Finance Calculator
# ================================
# What is your name? Alice
# Hello, Alice! Let's manage your finances.

Collect Income Information

Ask the user for their monthly income:

• Prompt for monthly salary/income
• Convert the input to a number (float) for calculations
• Store in a descriptive variable name (e.g., monthly_income)

# Example:
# Enter your monthly income: 50000

Collect Expense Information

Ask the user for their monthly expenses in these categories:

• Rent/Housing - Monthly rent or housing costs
• Food - Groceries and dining out
• Transportation - Fuel, public transport, etc.
• Utilities - Electricity, water, internet, phone
• Entertainment - Movies, subscriptions, hobbies

Each expense should be stored in its own variable with a descriptive name.

Calculate Totals

Perform the following calculations:

• Total Expenses: Sum of all expense categories
• Monthly Savings: Income minus total expenses
• Savings Percentage: (Savings / Income) * 100
• Expense Percentage: (Total Expenses / Income) * 100

# Calculation examples:
total_expenses = rent + food + transport + utilities + entertainment
monthly_savings = monthly_income - total_expenses
savings_percent = (monthly_savings / monthly_income) * 100

Display Financial Summary

Show a formatted summary using f-strings:

• Display each expense category with its amount
• Show total expenses and monthly savings
• Display percentages with 1 or 2 decimal places
• Use separators (like dashes) to make it readable

# Example output format:
# ========== Financial Summary for Alice ==========
# Monthly Income:        Rs. 50000.00
# --------------------------------------------------
# Expenses Breakdown:
#   Rent/Housing:        Rs. 15000.00
#   Food:                Rs. 8000.00
#   Transportation:      Rs. 3000.00
#   Utilities:           Rs. 2500.00
#   Entertainment:       Rs. 4000.00
# --------------------------------------------------
# Total Expenses:        Rs. 32500.00
# Monthly Savings:       Rs. 17500.00
# --------------------------------------------------
# You are saving 35.0% of your income!

Provide Financial Feedback

Based on the savings percentage, display a message:

• If savings >= 30%: "Excellent! You are a great saver!"
• If savings >= 20%: "Good job! You have healthy saving habits."
• If savings >= 10%: "Not bad, but try to save a bit more."
• If savings >= 0%: "Warning: You are barely saving. Review your expenses."
• If savings < 0%: "Alert! You are spending more than you earn!"

# Use if/elif/else for this logic
if savings_percent >= 30:
    print("Excellent! You are a great saver!")
elif savings_percent >= 20:
    # ... and so on

Code Quality Requirements

Your code must follow these standards:

• Comments: Add a header comment with your name, date, and program description
• Comments: Add comments explaining each section of your code
• Variables: Use descriptive snake_case variable names
• Indentation: Use 4 spaces for all indented blocks
• Blank lines: Separate logical sections with blank lines

# ================================
