This seems to be getting me further than any other website that talks about installing the latest Python. I seem to still be having trouble though. In the terminal, I get the correct file directory for the patch, however I get this error message

“patch unexpectedly ends in the middle of line
patch: **** Only garbage was found in the patch input.”

What do you think I am doing incorrectly?

Readline seemed to install nicely, but…

@Alan Williams

You don’t need to install Python 3.0 to explore the language. Why don’t your try the default python installation (version 2.5.1).
Just open terminal, type python and press enter. To exit type Ctrl-D or type these lines (followed by enter):

import sys
sys.exit()

Happy hacking

@Alan Williams : I guess there is nothing wrong in learning something new after 20 years of Mac experience. And no, python is not visual basic.

Far and away too difficult for me. I have used macs 20 years but have no Terminal experience.
I guess Python is not so simple after all.

@Greg: I’m sorry, but I tested this only on a x86 Macbook, and I have no idea on how to make it work for PPC..

Does this work on PPC as well as x86? My poor PowerBook seems to hang every time I get to:

gcc Python.framework/Versions/3.0/Python -o python.exe \
Modules/python.o \
-ldl

@Arkham: Thanks for the info. That’s what I thought (about the command line functionality). I read something about the BSD license in the default Python manual, I think. All in all it’s just burocracy.

I’ll stay with readline support, which goes pretty well with my bash setup. I even got history-search-backward (and forward) and other stuff through bindings in my .inputrc. Very nice indeed. I guess you can configure that sort of thing with editrc but didn’t want to learn another set of functions for now (I’m a Unix newbie and already studying enough subjects).

It’s a shame Python docs do not mention the readline configure option. I’m glad you posted this

Cheers!

@expora: Python’s interactive interpreter usually doesn’t support commands history, auto completion and auto indentation: compiling it against readline adds these functions. Mac OS X uses in fact libeditline by default even if it offers a lot less functionalities, just because it is BSD-licensed while libreadline is “tainted” by the GPL.
And I’ve found out about “–with-readline-dir” searching on Internet and it seems undocumented but nonetheless apparently existing
