It needn't be. 
>>> from json import tool
>>> tool.__file__
'/usr/lib/python2.7/json/tool.pyc'
>>> 

json is a package and tool is one of the modules inside that. 

To get to this, I have a little shell function that I stole from Anand that has
been super useful repeatedly. 

epy () {
        cmd="import $1 as a ; print a.__file__.endswith('.pyc') and a.__file__[:-1] or a.__file__" 
        file=$(/usr/bin/env python -c $cmd) 
        echo $file
        emacsclient --no-wait $file
}

If you want to read the source for the json module, just do

$ epy json 

and the json module is loaded into Emacs.
