Project: Create a program that calculates the interest on a loan. This program should make it easy for the user to enter numbers. Sample Console Display: Welcome to the Interest Calculator Enter loan amount: Enter interest rate: 12.275 S100,000 Loan amount: Interest rate: Interest amount: C100,000.00 2.2754 2, 275.00 Continue? (y/n): y Enter loan amount: Enter interest rate: 4.39 65K Loan amount: Interest rate: Interest amount: Ce5,000.00 4.390% $2,853.50 Continue? (y/n): n Bye! Specifications Use the Decimal class to make sure that all calculations are accurate. It should round the interest that's calculated to two decimal places, rounding up if the third decimal place is five or greater. The interest rate that's displayed can have up to 3 decimal places. Assume that the user will enter valid decimal values for the loan amount and interest rate with these exceptions: • If the user enters a dollar sign ($) at the beginning of the loan amount, remove it from the string before converting the string to a number. • If the user enters a comma in the loan amount, remove it from the string before converting the string. • If the user enters a Kat the end of the loan amount, remove the K from the end of the string, and multiply the loan amount by 1000. For example, a loan amount of SOK should be converted to a value of 50,000. • If the user enters a percent sign ($) before or after the interest rate, remove it from the string before converting the string to a number. Save the file with the filename xxx_interest py (where xxx = your initials) or as defined by your instructor.

I need help with my homework on python. but I have tried to do this code and it had a maroon icon pop open on the program when I ran the item.

def interest():
    amt = input("Enter loan amount: ")
    interest = (input("Enter interest rate: "))
    

    int_rate = interest.replace('%','')
    int_rate1 = float(int_rate)
    
    for ik in amt:
        if ik == 'k':
          amt_loan = amt.translate({ord(i): None for i in '$k,'})
          loan = int(amt_loan) * 1000
          roi = float(int_rate1 / 100)
          a = loan * (1 + roi)
          total_int = a - loan
          print(loan)
          print(total_int)
    
           
          
  # remove $ sign or , from the amount if any
        else:
            if ik == '$' or ik == ',':
               amt_loan = amt.translate({ord(i): None for i in '$,'})
               amt_l = int(amt_loan)
               roi =float(int_rate1 / 100)
               A = amt_l* (1 + roi)
               total_int = A - amt_l
               print("Totoal: amount:", amt_l)
               print("total interest:",total_int)
    ch = input("Countinue : (Y/N)")
    if ch == 'Y' or 'y':
        interest()
    else:
        print("Bye!")
interest()

But when I do it it says this Traceback (most recent call last):
  File "C:/Users/module>
    interest()
  File "C:/Users//AppData/Local/Programs/Python/Python39/.py1.py", line 33, in interest
    interest()
TypeError: 'str' object is not callable

What do I need to do to fix it onto the python program? Here is the image for my homework.
