试图找到一个python library或找到最好的方法来找到方法python code files

例如，app.py 

from django.conf.urls import url
from oscar.core.loading import get_class


class SearchApplication(Application):
    name = 'search'
    search_view = get_class('search.views', 'FacetedSearchView')
    search_form = get_class('search.forms', 'SearchForm')

    def get_urls(self):

        # The form class has to be passed to the __init__ method as that is how
        # Haystack works.  It's slightly different to normal CBVs.
        urlpatterns = [
            url(r'^$', search_view_factory(
                view_class=self.search_view,
                form_class=self.search_form,
                searchqueryset=self.get_sqs()),
                name='search'),
        ]
        return self.post_process_urls(urlpatterns)

我的目标是编写代码，将该文件app.py作为文本或文件的输入（任何一种方式都可以）并输出如下内容：

{
   "methods": [
        {"name": "get_urls", "class": "SearchApplication", "line": 9, "args": [self], "kwargs": []}
     ],

  "classs": [
    {"name": "SearchApplication", "inherits_from": "Application", "line": 5}
  ]   
}

谢谢。请询问意图是否不清楚或问题是否缺少数据。

使用ast.parse

    file_content = open('/path_to_file', 'r').read()
    parsed_result = ast.parse(self.file_content)
    for element in parsed_result.body:
        results = self.index_element(element)


def index_element(self, element, class_name=None):
    '''

        if element is relevant, meaning method -> index
        if element is Class -> recursively call it self

    :param element:
    :param class_name:
    :return: [{insert_result: <db_insert_result>, 'structured_data': <method> object}, ...]
    '''
    # find classes
        # find methods inside classes
    # find hanging functions

    # validation on element type
    if self.should_index_element(element):
        if self.is_class_definition(element):
            class_element = element
            indexed_items = []
            for inner_element in class_element.body:
                # recursive call
                results = self.index_element(inner_element, class_name=class_element.name)
                indexed_items += results

            return indexed_items
        else:
            structured_data = self.structure_method_into_an_object(element, class_name=class_name)
            result_graph = self.dal_client.methods_graph.insert_or_update(structured_data)
            return "WhatEver"

    return "WhatEver"

element对象具有函数/类的属性。
