  settings.
  + Fix all errors >= E300.
- Place unconditional imports at the beginning of the file.
- Do not import more than one module at the same time.
- Do not use blackslash at EOL within brackets.
- Do not use bare except.
- Do not end statement with semicolon.
- Do not place multiple statements in the same line.
- Use «is» and «is not» instead of «==» and «!=» for None.
