There’s a built-in Python function called vars that can be useful in analyzing a Python object.
Just as running
dir(the_object)returns a listing of all of the attributes of an object, including it’s methods, the following code, will return key/value pairs for the named attributes (variables), but NOT the methods (functions):
for k, v in vars(the_object).items():
print k,v
import sys
sys.getsizeof(object) # or
sys.getsizeof(object.attribute) Can also be useful, however the complete amount of memory is often hidden behind references.
Lastly (for now) there’s a relatively new Python package called dill that is a wrapper (interface?) for Python’s pickle package, and dill has a class called detect that returns a whole bunch of details about python objects:
dill.detect.PY3 dill.detect.children dill.detect.iscode dill.detect.nested dill.detect.reference
dill.detect.at dill.detect.code dill.detect.isframe dill.detect.nestedcode dill.detect.trace
dill.detect.baditems dill.detect.errors dill.detect.isfunction dill.detect.outermost dill.detect.varnames
dill.detect.badobjects dill.detect.freevars dill.detect.ismethod dill.detect.parent
dill.detect.badtypes dill.detect.globalvars dill.detect.istraceback dill.detect.parents
