函数参数不应该使用可变变量,只是也不是完全没有作用,比如可以缓存结果啊Orz，把以前写的一个函数改写了下直观了一些

	# from __future__ import unicode_literals

	# 兼容2和3

ficapy / get_function_args_value.py

Created July 22, 2015 10:51

返回函数参数名和传入参数值的dict表

	def foo(f, b):
	c = 3
	# 以下写法错误,locals是会变化的即使使用list(locals())依然无法得到正确的结果
	# [locals.get(i) for i in locals()]
	# 以下2、3通用
	frame = inspect.currentframe()
	args, _, _, value = inspect.getargvalues(frame)
	print({i:value.get(i) for i in args})

	foo(1, 2)

json序列化使用default参数简单忽略错误

	import json
	from bson import ObjectId

	a = {'1': ObjectId('53ef2d847f55f618ce13f24')}


	def default(o):
	"""Implement this method in a subclass such that it returns
	a serializable object for ``o``, or calls the base implementation
	(to raise a ``TypeError``).

Here are some things you can do with Gists in GistBox.

	// Use Gists to store code you would like to remember later on
	console.log(window); // log the "window" object to the console

pyquery依赖

	wget "https://bootstrap.pypa.io/get-pip.py"
	python get-pip.py
	sudo apt-get build-dep -y python-lxml (#该步骤会下载一百多M的依赖包安装)
	pip install pyquery
	亦或者直接安装python-lxml包
	如果你不需要将pyquery安装到虚拟环境中，那么直接安装python-pyquery包是最简单的~~~

	用上面的办法实在是因为各种测试网上类似的
	sudo apt-get install libxml2-dev libxslt1-dev python-dev zlib1g-dev #诸如此类不给力才有此下策
