3.2. Temperature Conversion

For this task, you need to write a function named convert that converts temperature values in Fahrenheit to Celcius and vice versa. The function will take 2 arguments, an integer and a one-character string. The integer will denote the temperature and the string will denote the unit of temperature. (‘F’ means that the given temperature is in Fahrenheit and ‘C’ means that it is in Celcius). If the unit is not ‘F’ or ‘C’, you should simply return “invalid unit”. If the given unit is valid, then the function must return a float as the result of conversion.

Hint: You can use the formula \(\frac{C}{100} = \frac{F-32}{180}\). In this formula, \(C\) is the value in Celcius and \(F\) is the value in Fahrenheit.

Sample I/O:

>>> convert(-35, 'C')
-31.0

>>> convert(212, 'F')
100.0

Show the Answer

def convert(temperature, unit):
    if(unit == 'C'):
        new_temperature = (180/100) * temperature + 32
        return new_temperature

    elif(unit == 'F'):
        new_temperature = (100/180) * (temperature - 32)
        return new_temperature

    else:
        return "invalid unit"
