如何获取特定Python模块中的变量列表？

Question

我们假设我有以下文件结构:

data.py

foo = []
bar = []
abc = "def"

core.py

import data
# do something here #
# a = ...
print a
# ['foo', 'bar', 'abc']

我需要获取data.py文件中定义的所有变量.我怎样才能做到这一点？我可以使用dir(),但它返回模块的所有属性,包括__name__等等.

Answer 1

print [item for item in dir(adfix) if not item.startswith("__")]

通常是这样做的秘诀,但它引出了一个问题.

为什么？

Answer 2

#!/usr/local/bin/python
# coding: utf-8
__author__ = 'spouk'

def get_book_variable_module_name(module_name):
    module = globals().get(module_name, None)
    book = {}
    if module:
        book = {key: value for key, value in module.__dict__.iteritems() if not (key.startswith('__') or key.startswith('_'))}
    return book

import config

book = get_book_variable_module_name('config')
for key, value in book.iteritems():
    print "{:<30}{:<100}".format(key, value)

示例配置

#!/usr/local/bin/python
# coding: utf-8
__author__ = 'spouk'

import os

_basedir = os.path.abspath(os.path.dirname(__file__))

# database section MYSQL section
DBHOST = 'localhost'
DBNAME = 'simple_domain'
DBPORT = 3306
DBUSER = 'root'
DBPASS = 'root'

# global section
DEBUG = True
HOSTNAME = 'simpledomain.com'
HOST = '0.0.0.0'
PORT = 3000
ADMINS = frozenset(['admin@localhost'])
SECRET_KEY = 'dfg45DFcx4rty'
CSRF_ENABLED = True
CSRF_SESSION_KEY = "simplekey"

结果函数
