def temp(T, from_unit, to_unit):
    conversion_table = {('c', 'k'):lambda x: x + 273.15,
                        ('c', 'f'):lambda x: (x * (9.0/5)) + 32,
                        ('k', 'c'):lambda x: x - 273.15,
                        ('k', 'f'):lambda x: (x * (9.0/5)) - 459.67,
                        ('f', 'c'):lambda x: (x - 32) * (5.0/9),
                        ('f', 'k'):lambda x: (x + 459.67) * (5.0/9)}
    f = conversion_table[(from_unit.lower(), to_unit.lower())]
    return f(T)

Would this be correct?
