It's also sad to see that deprecation warnings are completly ignored. Python 3.3 was release in 2011, 5 years ago.
I would prefer to show deprecation warnings by default. But I know that it's an old debate: developers vs users :-) I like to see my users as potential developers ;-)
This is tracked in this issue: http://bugs.python.org/issue24294 http://bugs.python.org/issue24294 : DeprecationWarnings should be visible by default in the interactive REPL IPython have enabled them only if they come from __main__. From totally subjective experience, that has already pushed a few library to update their code to new apis[1]. -- M [1] or sometime to wrap code in ignore warnings...
