Confusing Python version
<p>On my Mac OS X Lion, I type the following in Terminal:</p>

<pre><code>hobbes3@hobbes3:~$ which python
/usr/local/bin/python
hobbes3@hobbes3:~$ python
Python 2.7.1 (r271:86832, Jun 16 2011, 16:59:05) 
[GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
&gt;&gt;&gt; ^D
hobbes3@hobbes3:~$ /usr/local/bin/python
Python 2.7.2 (default, Feb 23 2012, 00:05:44) 
[GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.1.00)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
&gt;&gt;&gt; 
</code></pre>

<p>Part of my <code>/usr/local/bin/</code> looks like this:</p>

<pre><code>lrwxr-xr-x   1 root  wheel    32B Feb 23 00:07 pydoc -&gt; ../Cellar/python/2.7.2/bin/pydoc
lrwxr-xr-x   1 root  wheel    33B Feb 23 00:07 python -&gt; ../Cellar/python/2.7.2/bin/python
lrwxr-xr-x   1 root  wheel    40B Feb 23 00:07 python-config -&gt; ../Cellar/python/2.7.2/bin/python-config
lrwxr-xr-x   1 root  wheel    36B Feb 23 00:07 python2.7 -&gt; ../Cellar/python/2.7.2/bin/python2.7
lrwxr-xr-x   1 root  wheel    43B Feb 23 00:07 python2.7-config -&gt; ../Cellar/python/2.7.2/bin/python2.7-config
lrwxr-xr-x   1 root  wheel    34B Feb 23 00:07 pythonw -&gt; ../Cellar/python/2.7.2/bin/pythonw
lrwxr-xr-x   1 root  wheel    37B Feb 23 00:07 pythonw2.7 -&gt; ../Cellar/python/2.7.2/bin/pythonw2.7
</code></pre>

<p>Why is it that the first time I type <code>python</code> I get v2.7.1, but when I type the full path <code>/usr/local/bin/python</code> I get v2.7.2?</p>

<p>I installed v2.7.2 using homebrew, and I would like to use that version because I believe my Django is installed under v2.7.2 python.</p>
