In Python:

Temperatures in Fahrenheit can be converted into temperatures in Celsius using the equation

C = 5/9(F 32)

where F is the temperature in Fahrenheit, and C is the temperature in Celsius. Write a function celsius that takes in a temperature in Fahrenheit and returns the equivalent temperature in Celsius.

For example, celsius(32) should return 0.0 , and celsius(0) should return -17.77777777777778 .
