Why the second loop doesnt work

The second loop doesnt work. When I compile it doesnt output any text, it just asks for the inputs and stops there

It means that the second loop isnt being executed, just the first one but i dont know why

balance0 = float(input("balance = " ))
annualInterestRate = float(input("annualInterestRate = " ))
monthlyPayment = 10
balance = 0


month = 1
while (0):
 balance = balance0
 while month <= 12:
    balance1= (balance + annualInterestRate * balance/12)
    balance1 = balance1 - (monthlyPayment)
    print("Remaining balance month " , month, " is ", balance1)
    balance = balance1
    month += 1
 if balance < 0:
       print("Lowest payment: ", monthlyPayment)
       break

 else: 
     monthlyPayment += 10

The loop

     while month <= 12

doesnt make it to run, why?

Everyone else already caught teh main problem. You also neglected to reset your month counter. The result is that if $10/month doesn't pay off the loan, you go into an infinite loop. Try this:

while (True):
  balance = balance0
  for month in range(1, 12+1):

When you know how many times you need to iterate, use a for statement.

Also, you might use a better customer prompt: annualInterestRate is a variable anem, and hard for a mundane human to read. Change this to "Annual interest rate; e.g. 0.12 would mean 12% interest".

It's actually your outer loop that doesn't run. You have:

while (0):

Since (0) is never a true condition, that loop will never execute. Based on the fact that you've got a break in there later on to terminate it when some condition is met, you probably mean:

while (1):

As an aside, while True: is generally equivalent, and probably more idiomatic.
