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) and indicate the temperature scale of the temperature just entered and call the appropriate function from the temps module also if the Celsius temperature is being determined, it should be displayed accurate to three decimal places

Answer 1

temps.py

def c_to_f(celsius):
    """
    :param celsius:
    :return: None
    """
    print('{:.3f}'.format(
        (celsius * (9 / 5)) + 32
    ))


def f_to_c(fahrenheit):
    """
    :param fahrenheit:
    :return: float
    """
    return (fahrenheit - 32) * (5 / 9)

temps_main.py

from temps import c_to_f, f_to_c


def main():
    temp = float(input('Enter the temperature : '))
    c_or_f = input('Enter the unit  `C` for celsius and `F` for fahrenheit : ').lower()[0]
    if c_or_f == 'c':
        print("Temp in celsius : {}".format(temp))
        print("Temp in fahrenheit : ", end='')
        c_to_f(temp)
    elif c_or_f == 'f':
        print("Temp in fahrenheit : {}".format(temp))
        print("Temp in celsius : {:.3f}".format(f_to_c(temp)))
    else:
        print('invalid format!!')


if __name__ == '__main__':
    main()

#OUT

Run1
Enter the temperature : 34
Enter the unit  `C` for celsius and `F` for fahrenheit : c
Temp in celsius : 34.0
Temp in fahrenheit : 93.200

Run2
Enter the temperature : 93.2
Enter the unit  `C` for celsius and `F` for fahrenheit : f
Temp in fahrenheit : 93.2
Temp in celsius : 34.000

Please do comment if u have any concern...
