Challenge problem I asked at the end of the video:
Write a set of conditional statements to find whether or not a number is a “special” number
Special numbers are defined as numbers less than 100 or greater than or equal to 300 that are perfectly divisible by 3, 7, or both
Print out “Divisble by both” if special number divisible by both 3 & 7
Print out “Divisble by 3” if special number divisible by 3, but not 7
Print out “Divisible by 7” if special number divisible by 7, but not 3
#Print out “Not a special number” otherwise

Good job. Although you don't need the "not" part in the nested loops since they are redundant. If they were true, the first if statement would have triggered already. Keep it up mate!

Seems to work nicely. import random import math # Special numbers - < 100, >= 300, and divisible by 3,7 or both i = random.randint(0, 500) if i < 100 or i >= 300: if (i % 3) == 0 and (i % 7) == 0: print("Super Special Number ", i) elif (i % 3) == 0: print("Special Little Number ", i) elif (i % 7) == 0: print("Big Special Number ", i) else: print("Not a Special Number", i) else: print("Not a special number", i)
