Question

Write a Python program that can convert a Fahrenheit temperature to Celsius, or vice versa. The program should use two custom functions, f_to_c and c_to_f, to perform the conversions. Both of these functions should be defined in a custom module named temps. Custom function c_to_f should be a void function defined to take a Celsius temperature as a parameter. It should calculate and print the equivalent Fahrenheit temperature accurate to three decimal places. Custom function f_to_c should be a value-returning function defined to take a Fahrenheit temperature as a parameter. This function should calculate the equivalent Celsius temperature and return it. In the main function, your program should: prompt the user to enter a temperature (as a float type). indicate the temperature scale of the temperature just entered. call the appropriate function from the temps module. if the Celsius temperature is being determined, it should be displayed accurate to three decimal places

EXAMPLE OUTPUT 1

Enter a temperature 32
Was that input Fahrenheit or Celsius c/f? f
32.0 Fahrenheit equals 0.000 Celsius

EXAMPLE OUTPUT 2

Enter a temperature 100
Was that input Fahrenheit or Celsius c/f? c
100.0 Celsius is 212.000 Fahrenheit

Answer 1

def f_to_c(f):
    return (f - 32) / 1.8


def c_to_f(c):
    return 1.8 * c + 32


def main():
    temp = float(input("Enter a temperature "))
    choice = input("Was that input Fahrenheit or Celsius c/f? ")
    if choice == 'f':
        c = f_to_c(temp)
        print("{} Fahrenheit equals {:.3f} Celsius".format(temp, c))
    elif choice == 'c':
        f = c_to_f(temp)
        print("{} Celsius equals {:.3f} Fahrenheit".format(temp, f))
    else:
        print("Invalid choice")


main()
