Question

In PS 1A what is the significance of the ',2' in
# Minimum monthly payment of balance at start of the month
minPayment = round(minMonthlyPaymentRate * balance,2)

Also, what is '+=' ?

Answer 1

In Python, the `,2' in the round function is the number of digits after the decimal point ( http://docs.python.org/2/library/functions.html#round).

And `a += 2' means `a = a + 2'.

Answer 2

Thank you!
