However, this didn't happen in python2.7.2. Do I have to keep out from a construction zone? How would I know? {{{ % python -c 'import tempfile; print tempfile.mktemp(".dat")' Traceback (most recent call last): File "<string>", line 1, in <module> File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/tempfile.py", line 32, in <module> import io as _io File "/Users/renz/code/cpl/io.py", line 217, in <module> ... }}} -- Ticket URL: <https://trac.macports.org/ticket/40227#comment:3> MacPorts <http://www.macports.org/> Ports system for OS X

It looks like you've just been lucky up to now that having your own module named `io` did not conflict with the one in the standard library. For the record, as part of the fixes for [http://bugs.python.org/issue16800] which was released in Python 2.7.4, the `tempfile` module was changed to use `io`. Shadowing of module names is a common trap. Probably the best general way to avoid it is by structuring your project as one or more Python packages thereby putting your modules in their own namespace (see http://docs.python.org/2/tutorial/modules.html#packages). -- Ticket URL: <https://trac.macports.org/ticket/40227#comment:5> MacPorts <http://www.macports.org/> Ports system for OS X

Either rename the user module that conflicts with the standard library one or restructure the user program to use its own package namespace. -- Ticket URL: <https://trac.macports.org/ticket/40227#comment:8> MacPorts <http://www.macports.org/> Ports system for OS X
