is it possible to add dictionary property to module.  we can add dictionary property to classes with adding __getitem__ method. i hope we can do that same thing on modules.

example

import mymodule

print( mymodule["2 + 2"]  )

# output =>  '4'

---

I tried it but it not working

#mymodule.py

__dict__ = {"2 + 2": "4",  "python": 3.4, "os": "fedora"}

def __getitem__(key):
    return __dict__[key]

So far as I'm aware, this isn't possible. Why do you want to do it? We might be able to suggest a different way of achieving your goal.

Why not just have a thing in the module that does that, instead of having the module itself do it?

If want to import can do it like this,remember a module is just a single Python file.

>>> from bar import mymodule
>>> mymodule('2 + 2')
'4'
>>> mymodule('os')
'fedora'
>>> mymodule('java')
'Not in record'

# bar.py
def mymodule(arg):
    return {
        "2 + 2": "4",
        "python": 3.4,
        "os": "fedora"
        }.get(arg, 'Not in record')

thanks for answer. i want only good code view but python sometimes can be very annoying. okay. at least i learned that is not possible.
