How can I get a reference to a module from within that module? Also, how can I get a reference 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

You can pass it in from outside:

mymod.init(mymod)

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