Compute an investment report.

1. The inputs are
       starting investment amount 
       number of years
       interest rate (an integer percent)

2. The report is displayed in tabular form with a header.

3. Computations and outputs:
       for each year
          compute the interest and add it to the investment
          print a formatted row of results for that year
 
4. The total investment and interest earned are also displayed.
“””
# Accept the inputs from the user
startBalance = float(input(“Enter the investment amount: “))
years = int(input(“Enter the number of years: “))
rate = int(input(“Enter the rate as a %: “))
 
# Convert the rate to a decimal number
rate = rate / 100
# Initialize the accumulator for the interest
totalInterest = 0.0
# Display the header for the table
print(“%4s%18s%10s%16s” % \
      (“Year”, “Starting balance”,
       “Interest”, “Ending balance”))
# Compute and display the results for each year
for year in range(1, years + 1):
    interest = startBalance * rate
    endBalance = startBalance + interest
    print(“%4d%18.2f%10.2f%16.2f” % \
          (year, startBalance, interest, endBalance))
    startBalance = endBalance
    totalInterest += interest
# Display the totals for the period
print(“Ending balance: $%0.2f” % endBalance)
print(“Total interest earned: $%0.2f” % totalInterest)
 
 
Output

Enter the investment amount: 250000
Enter the number of years: 25
Enter the rate as a %: 12.5
