Flake8 Program Still Finds Errors when There Appears to be None

I'm following the video for badpep8.py and the errors appear to be cleared out but flake8 appears to be finding more errors. Not sure why this is happening?

# multiple imports
def foo_bar(arg1, arg2, arg3, arg4):
    # way too much indentation
    return arg1, arg2, arg3, arg4

def bar(*args):
    # bad spacing
    return 2 + 2

# Bad class name, bad spacing, bad indentation
class Treehouse:
    def one(self):
        return 1

    def two(self):
        return 2


# bad identation and whitespace
alpha, beta, charlie, delta = foo_bar(
    "a long string", 
    "a longer string", 
    "yet another long string",
    "and other crazy string"
)


# bad spacing
one = 1
three = 3
fourteen = 14  # make fourteen equal to 12

print(alpha)
print(fourteen)

print(Treehouse().two())

This is what prints to the console:

Those should be relatively easy to pass with the description and good ol' fashioned trial and error. I think one of the first things you should do is delete all the comments. I think that's going to help you clear up some of that whitespace that it is not liking.

Well I kinda figured most of it out. There can be trailing white space and indented white space. It's sometimes about going line by line and getting rid of each.
