Question

I\'m a little confused with the python on osx. I do not know if the previous owner of the laptop has installed macpython using macport. And I remembered that osx has an buil

Answer 1

[GCC 4.2.1 (Apple Inc. build 5646)] is the version of GCC that the Python(s) were built with, not the version of Python itself. That information should be on the previous line. For example:

# Apple-supplied Python 2.6 in OS X 10.6
$ /usr/bin/python
Python 2.6.1 (r261:67515, Jun 24 2010, 21:47:49) 
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> 

# python.org Python 2.7.2 (also built with newer gcc)
$ /usr/local/bin/python
Python 2.7.2 (v2.7.2:8527427914a2, Jun 11 2011, 15:22:34) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>>

Items in /usr/bin should always be or link to files supplied by Apple in OS X, unless someone has been ill-advisedly changing things there. To see exactly where the /usr/local/bin/python is linked to:

$ ls -l /usr/local/bin/python
lrwxr-xr-x  1 root  wheel  68 Jul  5 10:05 /usr/local/bin/python@ -> ../../../Library/Frameworks/Python.framework/Versions/2.7/bin/python

In this case, that is typical for a python.org installed Python instance or it could be one built from source.

Answer 2

I have a cook recipe for finding things in linux/macos

First update the locate db then do a

locate WHATiWANTtoSEARCH | less

do a /find to find what you are looking for.

to update your locate db in macos do this:

sudo /usr/libexec/locate.updatedb

it sometimes takes a while. Hope this helps :)

On High Sierra

Answer 6

which python3 simply result in a path in which the interpreter settles down.
