iOS Development Techdegree Student 5,252 PointsNot putting else in your list comprehension
fizzbuzz = [ 'Fizzbuzz' if num % 15 == 0 else
'Fizz' if num % 3 == 0 else
'Buzz' if num % 5 == 0 else
num for num in range (1, 101) ]
This is actually (a) allowed, (b) elegant and readable, and (c) a lot like pattern matching in other languages.
[edit: Added python formatting -cf]

Treehouse Guest TeacherI actually find that difficult to read. It could probably be tackled a cleaner way outside of a comprehension.
That said, yes, you can use else in a comprehension. You can't use it (at least in my experience, research, and testing) like you do in a "ternary" operation name = "Kenneth" if a < 2 else "Bob".
But, yeah, once your list comp breaks 2 lines, you should probably find another solution.

def fizz_or_buzz(num):
if num % 15 == 0:
return 'Fizzbuzz'
elif num % 3 == 0:
return 'Fizz':
elif num % 5 == 0:
return 'Buzz'
else:
return num
fizzbuzz = [fizz_or_buzz(nun) for num in range (1, 101)]
