What are the differences between processes and threads in Python? 原文是2.x版本的,然后应该是英文的.我在学习的过程中,同时改成python 3.3并且改成中文,引入一些自己的理解. Thread Objects 线程对象 The simplest way to use a Thread is to instantiate it with a target function and call start() to...

Last: threads are different from processes. A thread is a context of execution, while a process is a bunch of resources associated with a computation. A process can have one or many threads. Clarification: the resources associated with a process include memory pages (all the threads in a pro...
Lets you break up the function app into modular components, which enables you to define functions in multiple Python files and divide them into different components per file. Provides extensible public function app interfaces to build and reuse your own APIs. The following example shows how to use...
