Can Python Introspect Like Java?
"I come from a java background. Java has an API that list all classes and their methods that come with Java. Is there anything like that in python?"
At the Python interpreter prompt, invoking the dir function as follows...
...gives a list of defined classes and variables.
In certain interactive shells (or prompts), such as IPython, using the TAB key on one of the existing objects opens a list of possible completions, i.e. its methods/attributes. For other plainer shells, you can call the dir function supplying an object as an argument to see the contents of that object:
I'm not sure this is what the OP is asking. I think s/he's referring to the API documentation rather than the API itself. Calling help(object) in the interpreter is a good start for help on an object.
In fact, the dir and help built-in functions make use of Python's introspection capabilities. Another interface can be found in the standard library inspect module. -- PaulBoddie
CL's answer: no, Python cannot introspect like Java; it can only do better.
The DocumentationTools page provides details of tools which can produce API documentation for Python applications and libraries, such as that provided for wxPython (a GUI-building kit for Python): wxPython API documentation.
