An integer is just a number without a decimal part (for instance, -17, 0, and 42 are all integers, but 98.6 is not).
For the purpose of this lesson, we'll also say that a number with a decimal part that is all 0s is also an integer, such as 7.0.
This means that, for this lesson, you can't just test the input to see if it's of type int.
If the difference between a number and that same number rounded down is greater than zero, what does that say about that particular number?
def is_int(x): if type(x) == type(1): return True elif x - int(x) == 0: return True else: return False
Task counted as completed right.
I just want to hear opinions.
