• Write a Python script that computes monthly interest payments for a home or car loan.

  Inputs:	p = Loan amount (principal)
  	r = Interest rate in percent
  	n = Number of years (duration of loan)
  Output:	m = Monthly payment

  Here is the formula:

  m

  =

  p r / 1200.0 1 - (1.0 + r / 1200.0) 12 n

• Use prompts for input to let the user know what to input; use text to explain what the output means.
• Round the monthly payment is to the nearest cent.
• Use Cel2Fahr and Distance as examples.
• Optionally: validate p, r, and n with if statements to insure that they are all positive.
• Pseudocode for Project 1, including input validation:

  Input principal using prompt "Enter amount of loan: ", assign to variable p. If p is less than 0, print error message, exit program. End Input interest rate using prompt "Interest rate in percent: ", assign to variable r. If r is less than 0, print error message, exit program. End Input term using prompt "Number of years: ", assign to variable n. If n is less than 0, print error message, exit program. End Compute monthly payment using formula, assign to variable m. Output monthly payment m.
