Add the correct amount of whitespace between the functions/methods...

Not sure where I'm getting "5 error(s) on line(s) 8,10,4,12,14: no new line at end of file; blank line contains whitespace"

def first_function(arg1):
    return 'arg1 is {}'.format(arg1)


def second_function(arg1):
    return 'arg1 is {}'.format(arg1)


class MyClass:

    args = [1, 2, 3]

    def class_func(self):
        return self.args

[MOD: added ```python formating -cf]

It's not obvious but It's exactly like the error says: "5 error(s) on line(s) 8,10,4,12,14: no new line"

  • line(s) 8,10,4,12: The blank lines contains spaces which is the same as "trailing spaces"
  • 14: no new line: put the cursor after the last character and hit <Enter> so that the last line off code is followed by an End-of-Line character

Then you're good to go!

Thanks! Completely overlooked the whitespace(s) in the blank lines.
