Nick Coghlan added the comment: Ramchandra, as it turns out, if we deem an optimization semantically safe, we do it without -O, it we deem it unsafe, we don't do it at all.
Thus, the real effect is to remove assert statements and optimise code as if "__debug__" was replaced by a literal zero (effectively). So a more meaningful description would be: -O Removes assert statements and any code conditional on the value of __debug__. This changes the filename extension for compiled (bytecode) files from .pyc to .pyo.
