When I try to access the "HISTFILE" env var within a program, it isn't there
$ echo $HISTFILE
/Users/drewgross/.bash_history
$ python
Python 2.7.10 (default, Oct 23 2015, 19:19:21)

>>> import os
>>> os.environ['HISTFILE']
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/UserDict.py", line 23, in __getitem__
raise KeyError(key)
KeyError: 'HISTFILE'
But if I set it directly, it is:
$ HISTFILE=wat python

'wat'
It seems to be hidden for some reason. Why is that? Is there any way to access this var within my programs?
