introspection

[brad tilley]

How do I import a module and then ask it to show me its methods or other
aspects about itself during execution? I'd like to do something such as
this:

import win32api

print win32api.method s()

I'd like to write some test scripts that load modules and probe them for
information about themselves.

Hi Brad,

You might like to look at the built-in inspect module.

Cheers,
John

As well as the 'inspect' module, you may be able to get some distance
just with builtin functionality::

>>import re

>>dir(re)

['DOTALL', 'I', 'IGNORECASE', 'L', 'LOCALE', 'M', 'MULTILINE',
'S', 'U', 'UNICODE', 'VERBOSE', 'X', '__all__', '__builtins__',
'__doc__', '__file__', '__name__', 'compile', 'engine', 'error',
'escape', 'findall', 'finditer', 'match', 'purge', 'search',
'split', 'sub', 'subn', 'template']

>>[(n, getattr(re, n)) for n in dir(re)]

[('DOTALL', 16), ('I', 2), ('IGNORECASE', 2), ('L', 4), ('LOCALE',
4), ('M', 8), ('MULTILINE', 8), ('S', 16), ('U', 32), ('UNICODE',
32), ('VERBOSE', 64), ('X', 64), ('__all__', ['match', 'search',
'sub', 'subn', 'split', 'findall', 'compile', 'purge', 'template',
'escape', 'I', 'L', 'M', 'S', 'X', 'U', 'IGNORECASE', 'LOCALE',
'MULTILINE', 'DOTALL', 'VERBOSE', 'UNICODE', 'error',
'finditer']),
[...]
]

>>[n for n in dir(re) if hasattr(getattr (re, n), '__call__')]

['compile', 'escape', 'findall', 'finditer', 'match', 'purge',
'search', 'split', 'sub', 'subn', 'template']
