Python function help

Question

I have to write this same basic function six different times, changing the formula in the function each time. I need help getting the first function right.

we have a prompt like this for each of the functions we have to make: sp_comp_annual(present, interest, num_periods) - This function implements the formula for the Single Payment Compound Annual Factor. The three parameters correspond to the variables P, i, and n on the right side of the mathematical formula. The function will return the result of the computation, i.e., the value of F.

the formula for the current function is Compound Annual Factor F= P(1+i)^n

this is my current function

def sp_comp_annual(present, interest, num_periods):

  present,

  interest,

  num_periods,

  return present(1+interest)**num_periods

present = int(input("What is your present value of the money?:" ))

interest = float(input("What is your current interest?:" ))

num_periods = int(input("What is the number of interest periods?:" ))

F = sp_comp_annual(present,

interest,

num_periods,)

print(f"Compound Annual Factor: {F}")

Answer 1

Hi, I am wondering why you have written the argument variable names under the function before returning the formula. In python you do not need to define a variable, and when you pass it to the function, the function can immediately use it. I might be misunderstanding the question, but I think that having the function immediately return the formular should be what you are looking for.

def sp_comp_annual(present, interest, num_periods):

return present(1+interest)**num_periods
