How Do I Access Classes And Get A Dir() Of Available Actions?

I have been trying to get access to available functions for a Match Object from re.search. I am looking for a way to do that similar to how I could do dir(str) and I can find .repl

Solution 1:

In Python 3.7, re.Match is the type of the objects returned by re.match. See bpo30397.

In previous versions, re.Match is not defined. If you wanted a reference to the type of match objects you could get it with

Match = type(re.match('',''))

You can use dir on either the Match type or on a match object to list its attributes and methods.

Solution 2:

This is the closest thing I have gotten so far:

>>> import re, inspect

>>> inspect.getmembers(re,inspect.isclass)
[('Scanner', <class re.Scanner at 0xb7b7bcec>), ('_pattern_type', <type 
'_sre.SRE_Pattern'>), ('error', <class 'sre_constants.error'>)]

>>> from re import _pattern_type

>>> dir(_pattern_type)
['__class__', '__copy__', '__deepcopy__', '__delattr__', '__doc__', '__format__', 
'__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', 
'__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 'findall', 
'finditer', 'flags', 'groupindex', 'groups', 'match', 'pattern', 'scanner', 'search', 
'split', 'sub', 'subn']

Solution 3:

So apparently _sre is a C-extension so SRE_Match is defined within this C-file

Where can I find the _sre.py python built-in module?
