Get names and types of all attributes of a Python module (Python)

2016-10-06T17:21:42-07:00

Python recipe 580705 by Vasudev Ram (documentation, introspection, modules, reflection, type).

This recipe shows how to get the names and types of all the attributes of a Python module. This can be useful when exploring new modules (either built-in or third-party), because attributes are mostly a) data elements or b) functions or methods, and for either of those, you would like to know the type of the attribute, so that, if it is a data element, you can print it, and if it is a function or method, you can print its docstring to get brief help on its arguments, processsing and outputs or return values, as a way of learning how to use it.

The code for the recipe includes an example call to it, at the end of the code. Note that you first have to import the modules that you want to introspect in this way.

Clear Only Project Modules (Python)

2014-12-17T19:03:15-08:00

Python recipe 578982 by Cornelius Jatniel Prinsloo (clear, modules, project, reload, script, startup).

Useful for python sessions that have a long startup time because of external dependancies [In my case that would be pygame and pymunk] I've got a slow computer so it takes a while to startup this is the solution I came up with

import this before any other of your project imports example: import reloading # The modules in your project folder get cleared then load the rest of your project modules

make sure that the reloading script is in your project folder, or else it won't work

You might be able to extend this by changing line

Trace decorator for debugging (Python)

Python recipe 577551 by Kevin L. Sitze (classes, debug, debugging, decorators, functions, inspection, modules, trace). Revision 2.

This package provides a decorator for tracing function and method calls in your applications. The tracing capabilities are managed through the logging package, and several mechanisms are provided for controlling the destination of the trace output.

It also provides functionality for adding decorators to existing classes or modules.

Open a python module given it's name in Emacs (Bash)

PluginManager - Extending Project Functionality By Using Custom Modules/Plugins On The Fly. (Python)

2010-05-07T15:32:10-07:00

Python recipe 577216 by AJ. Mayorga (extending, extensible, modules, plugin). Revision 4.

This demo shows how you can create and manage your own custom plugins for extending functionality in your Python projects. There are no safety wrappers in this demo for restricting plugins aside from that fact that plugins are run as an extention of a management class which is run in its own instance only receiving data passed to it by the RumModules method, that said security should ideally be applied to the ModuleAPI class, by restricting __builtins__ on eval calls and/or validating plugin content and parameters which can be done by extending the Prepaser Class. For a great recipe/demo of restricting eval call see http://code.activestate.com/recipes/496746.

That aside it was alot of fun to write and use. Enjoy

PS: you will need http://code.activestate.com/recipes/577144/ to import Xceptions
