Thanks. I've attached a newer version with tests with all the issues fixed.

Subject: [PATCH] python-mode: Fix detection for opening blocks.
* python.el (python-info-dedenter-opening-block-positions): There
can't be any back-indented lines between an opening block and the
current line.
* python-tests.el (python-indent-electric-colon-4): Add an indent
test case where there is one-more indented previous opening block.
