Oops, I spoke too soon when I said that readline support with Leopard's Python works for me with IPython.
Many things DO work, but tab-completion does NOT. I am trying to get tab completion working. Forget IPython, just try this "unit test" of rlcompleter with the Python that ships with Leopard: See http://docs.python.org/lib/module-rlcompleter.html Launch python from a Terminal shell prompt. at the prompt, type the following commands: import rlcompleter import readline readline.parse_and_bind("tab: complete") Now, try it out: start some input, then hit the Tab key to get some possible completions: readline. <TAB PRESSED> The tab is passed as raw input, and the completer does not give any completions. Tried with both Terminal and xterm. Reported as Apple Bug # 5563035 I've also asked the IPython devs for help - and volunteered to get this resolved somehow for them -- but I don't think it's an IPython problem (since you can do this from "raw" interactive python).
