#48911: Output problem with Python 3.5 REPL --------------------+-------------------------------- Reporter: ronf@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.3 Keywords: | Port: python35 --------------------+-------------------------------- I installed the Python 3.5 port (@3.5.0) today on my 2011 iMac running Yosemite 10.10.5. When I tried to use the interactive read-eval-print loop, I saw an immediate problem with the printing of the prompt: {{{ Python 3.5.0 (default, Sep 15 2015, 23:58:24) [GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.56)] on darwin Type "help", "copyright", "credits" or "license" for more information.
1+2 3 }}}
The second ">>>" prompt was printed before the result of the evaluation. This same output on Python 3.4 is: {{{ Python 3.4.3 (default, Sep 4 2015, 09:52:14) [GCC 4.2.1 Compatible Apple LLVM 6.1.0 (clang-602.0.53)] on darwin Type "help", "copyright", "credits" or "license" for more information.

}}}
With 3.5, the prompt is printed too early and the cursor ends up on a blank line, but it does properly still accept another expression, repeating the problem with the prompt again on that evaluation. Hitting Ctrl-D to exit also prints an extra prompt before exiting: {{{ Python 3.5.0 (default, Sep 15 2015, 23:58:24) [GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.56)] on darwin Type "help", "copyright", "credits" or "license" for more information.

After a bit more experimentation, I was able to produce a similar problem with the Python 3.4 port, but only when I uninstalled the "py34-readline" package. In that case, both Python 3.4 (@3.4.3_5) and Python 3.5 (@3.5.0) have this issue. However, with "py34-readline" installed, the problem goes away. Unfortunately, there's no "py35-readline" package yet, so I can't test that as a possible solution. -- Ticket URL: <https://trac.macports.org/ticket/48911> MacPorts <https://www.macports.org/> Ports system for OS X
