Question 17: If Else

Sarah has $5000 saved up for her holiday shopping. She plans to buy gifts for her family and make a few purchases for herself. After calculating her expenses, she wants to divide the remaining amount into two parts: personal shopping and savings.

Here’s how to structure the problem:

1. Initial Setup:

   • Define a variable for Sarah’s initial savings and set it to $500.

2. Input Expenses:

   • Ask Sarah how much she spent on a new phone (phone_cost).
   • Ask her how much she spent on clothes (clothes_cost).
   • Ask how much she spent on a book (book_cost).
   • Ask how much she spent on a holiday decoration (decoration_cost).
   • Ask how much she spent on a special dinner (dinner_cost).

3. Calculate Remaining Balance:

   • Subtract the total expenses (phone_cost, clothes_cost, book_cost, decoration_cost, dinner_cost) from the initial savings.
   • Store the result in a variable called remaining_balance.

4. Decide Spending and Saving:

   • Ask Sarah how much she wants to allocate for personal shopping (personal_shopping).
   • Subtract this amount from the remaining_balance.
   • The rest should automatically go into savings.

5. Check Validity:

   • Use an if condition to ensure Sarah’s spending doesn’t exceed her remaining balance.
   • If it does, inform her that she needs to reduce her personal shopping amount.
   • Otherwise, confirm the split and display the final savings amount.

6. Display Result:

   • Use Streamlit’s st.columns to display the expenses, remaining balance, and the breakdown between personal shopping and savings.
