How to get a reference to a module inside the module itself?

How can I get a reference to a module from within that module? Also, how can I get a reference开发者_如何学Python to the package containing that module?

import sys
current_module = sys.modules[__name__]

One more technique, which doesn't import the sys module, and arguably - depends on your taste - simpler:

current_module = __import__(__name__)

Be aware there is no import. Python imports each module only once.

If you have a class in that module, then the __module__ property of the class is the module name of the class. Thus you can access the module via sys.modules[klass.__module__]. This is also works for functions.

You can get the name of the current module using __name__

The module reference can be found in the sys.modules dictionary.

See the Python documentation

According to @truppo's answer and this answer (and PEP366):

Reference to "this" module:

import sys
this_mod = sys.modules[__name__]

Reference to "this" package:

import sys
this_pkg = sys.modules[__package__]

__package__ and __name__ are the same if from a (top) __init__.py

You can pass it in from outside:

mymod.init(mymod)

Not ideal but it works for my current use-case.

If all you need is to get access to module variable then use globals()['bzz'] (or vars()['bzz'] if it's module level).
