     Type:  defect       |  Milestone:
 Priority:  Normal       |    Version:  2.3.4
Component:  ports        |       Port:  python2.6 python2.7 python3.3
 Keywords:               |  python3.4
-------------------------+-------------------------------------------------
 Currently running El Capitan, but pretty sure I saw this happen on
 Yosemite too. I suspect all MacPorts Python versions are affected, but can
 currently only test on the ones I have installed (2.6, 2.7, 3.3, 3.4).
 Notably, however, the system (non-MacPorts) Pythons do not have this
 issue.

 After starting python, and hitting enter once, the prompt lines (>>>, ...)
 only appear after hitting enter to finish the line they should appear on.
 ctrl-D no longer causes the REPL to exit.

 When exiting back to the shell, I find that typed input is buffered and
 not displayed until hitting enter, and then no newline is displayed before
 the next shell prompt appears. This is persistent until clear or reset is
 executed
