The Silent Void Thus spake the master programmer: “When you have learned to snatch the error code from the trap frame, it will be time for you to leave.” 1.1 Something mysterious is formed, born in the silent void. Waiting alone and unmoving, it is at once still and yet in constant motion. It is the source of all programs. I do not know its name, so I will call it the Tao of Programming....

Problem: Write a program that prints the numbers from 1 to 100. But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”. For numbers which are multiples of both three and five print “FizzBuzz”. f = lambda x: 'FizzBuzz' if not (x%5 or x%3) else 'Fizz' if not x%3 else 'Buzz' if not x%5 else str(x) for x in range(100): print(f(x)) Fizz Buzz problem
