Traceback (most recent call last): File "/home/coding/Documents/Python Repository/2 - Numbers & math (Loan Calclator).py", line 40, in monthly_payment = float(loan_amount) * [0.05 * (1.0 + 0.05) * float(num_of_payments)] / [(1.0 + 0.05) * float(num_of_payments) - 1.0] TypeError: can't multiply sequence by non-int of type 'float'

Answer 1

In your line:

    monthly_payment = float(loan_amount) * [0.05 * (1.0 + 0.05) * float(num_of_payments)] / [(1.0 + 0.05) * float(num_of_payments) - 1.0]

You are using square brackets (in this case used to create a list) as a means of specifying order of operations. This should be () type brackets.
