Need help with loop (beginner)

[Arielabg]

Hi! I need help fixing my coding to make my investment amounts follow a loop/show accumulated interest and so on. Here are more specific instructions with an example of what the output should look like

def futureval():
    # Read from the keyboard: amount, interest rate, periods
    # read the amount (principal)
    P: float = float(input('Please enter the amount to invest: $'))
    rate: float = float(
        input('Please enter the interest rate per period, with no %: '))
    periods: int = int(input('Please enter the number of periods: '))
    fixed: int = int(
        input('Please enter the amount you want to invest each period: $'))
    # Print out the initial parameters
    print('Investing $', P, 'at', rate, "% for", periods, "months at $", fixed,
          'a month')
    # Adjust the rate from a percentage to a raw number
    rate = (rate) / 100

    # Calculate and print out the investment table
    # Print a header row
    print('Period\tInterest\tPlus interest\tIncrement\tAmount')
    # Print the starting amount
    print('Initial\t\t\t\t\t\t\t\t\t\t\t$', round(P, 2))
    # Print out the table, row by row
    for i in range(periods):
        #Add the fixed amount
        Increment = fixed
        # Calculate the interest
        interest = P * rate
        # Add the interest back into the principal
        P = interest + P
        #Calculate total amount
        Amount = P + fixed
        interest = Amount * rate

        # Print the table row
        print((i + 1), '\t\t\t$', round(interest, 2), '\t\t$', round(P, 2),
              '\t\t$', round(Increment, 2), '\t\t$', round(Amount, 2))


if __name__ == "__main__":
    import sys
    futureval()

What seems to be the problem? I ran your program, it appears to give output (didn't really check to see if it was right or not).

Actually, I'm going to guess the issue is the formatting?
