Separate inline comments by at least two spaces.

An inline comment is a comment on the same line as a statement.
Inline comments should be separated by at least two spaces from the
statement. They should start with a # and a single space.

Each line of a block comment starts with a # and a single space
(unless it is indented text inside the comment).

Separate top-level function and class definitions with two blank lines.

Method definitions inside a class are separated by a single blank

Extra blank lines may be used (sparingly) to separate groups of
related functions.  Blank lines may be omitted between a bunch of
related one-liners (e.g. a set of dummy implementations).

Use blank lines in functions, sparingly, to indicate logical
sections.

Line too long (87 > 79 characters)
Open

                raise TLSClosedConnectionError("attempt to write to closed connection")
Severity: Minor
Found in tlslite/tlsrecordlayer.py by pep8

Limit all lines to a maximum of 79 characters.

There are still many devices around that are limited to 80 character
lines; plus, limiting windows to 80 characters makes it possible to
have several windows side-by-side.  The default wrapping on such
devices looks ugly.  Therefore, please limit all lines to a maximum
of 79 characters. For flowing long blocks of text (docstrings or
comments), limiting the length to 72 characters is recommended.

Severity: Minor
Found in tlslite/tlsrecordlayer.py by pep8

Avoid explicit line join between brackets.

The preferred way of wrapping long lines is by using Python's
implied line continuation inside parentheses, brackets and braces.
Long lines can be broken over multiple lines by wrapping expressions
in parentheses.  These should be used in preference to using a
backslash for line continuation.

  either side: assignment (=), augmented assignment (+=, -= etc.),
