Why doesn't "or" return a boolean?

num = '5'
result = num or None
print(result)  # 5

num = ''
result = num or None
print(result)  # None

I don't understand why this works because I thought "or" will check if one side is True and if so it will return True. But it returns either the value of num or None.

Because empty strings are False... – PilouPili Nov 12 '18 at 22:58
@Makoto Thanks. My priority was closure over dupe accuracy. – cs95 Nov 12 '18 at 23:00
