643aad17faEnable additional flake8 rules (practicalswift)f020aca297Minor Python cleanups to make flake8 pass with the new rules enabled (practicalswift) Pull request description: Enabled rules: ``` * E242: tab after ',' * E266: too many leading '#' for block comment * E401: multiple imports on one line * E402: module level import not at top of file * E701: multiple statements on one line (colon) * E901: SyntaxError: invalid syntax * E902: TokenError: EOF in multi-line string * F821: undefined name 'Foo' * W293: blank line contains whitespace * W606: 'async' and 'await' are reserved keywords starting with Python 3.7 ``` Note to reviewers: * In general we don't allow whitespace cleanups to existing code, but in order to allow for enabling Travis checking for these rules a few smaller whitespace cleanups had to made as part of this PR. * Use [this `?w=1` link](https://github.com/bitcoin/bitcoin/pull/12987/files?w=1) to show a diff without whitespace changes.
