import subprocess

def my_function(x):
    return x + 100

output = subprocess.Popen(my_function, 1) #I would like to pass the function object and its arguments
print output 
#desired output: 101

我只找到了使用单独脚本打开子进程的文档.有谁知道如何传递函数对象甚至是一种简单的方法来传递函数代码？

我正在尝试将分类变量的字符串数组转换为分类变量的整数数组.

防爆.

import numpy as np
a = np.array( ['a', 'b', 'c', 'a', 'b', 'c'])
print a.dtype
>>> |S1

b = np.unique(a)
print b
>>>  ['a' 'b' 'c']

c = a.desired_function(b)
print c, c.dtype
>>> [1,2,3,1,2,3] int32

我意识到这可以通过循环完成,但我想有一种更简单的方法.谢谢.

如何为通过安全cookie验证用户的龙卷风处理程序编写单元测试？这是我想通过的虚拟测试的代码(和sudo代码).我正在使用Tornado 3.1.

from tornado.web import  Application, RequestHandler
from tornado.escape import to_unicode, json_decode, json_encode
from tornado.testing import AsyncHTTPTestCase

class MainHandler(RequestHandler):
    """
    Base handler to authenticate user via a secure cookie.
    This is used for an API.
    """
    def get(self):

        user = self.get_secure_cookie('user')

        if user == 'user_email':
            self.write('sucess')
        else:
            self.write('fail')

class UserAPITest(AsyncHTTPTestCase):
    def get_app(self):
        self.app = Application([('/', MainHandler)],
                    cookie_secret='asdfasdf')
        return self.app

    def test_user_profile_annoymous(self):
        #SUDO CODE (what should go here?)
        #cookie = make_secure_cookie('user', 'user_email', cookie_secret)
        #headers = {'Cookie':cookie}

        response = self.fetch('/', method='GET', headers=headers) …

为什么我不能使用下划线(_)扩展来更新未在模式定义中定义属性的mongoose模型.有办法解决这个问题吗？

节点模型:

var mongoose = require('mongoose')
  , Schema = mongoose.Schema

var NodeSchema = new Schema({
    label: {type : String, default : 'none'}
}, { strict: false })

mongoose.model('Node', NodeSchema)

节点控制器:

var node = new Node();
node = _.extend(node, {"EXTENDNOTinSchema":"TRUE"});
console.log("extend: " + node);
node.set("SETNOTinSchema","TRUE");
console.log("set: " + node);

控制台输出:

extend: { __v: 0,
  _id: 50bb05656880a68976000001,
  label: 'none' }

set: { __v: 0,
  _id: 50bb05656880a68976000001,
  label: 'none' 
  SETNOTinSchema: TRUE}
