MQTT(Message Queuing Telemetry Transport,消息队列遥测传输协议),是一种基于发布/订阅(publish/subscribe)模式的"轻量级"通讯协议,该协议构建于TCP/IP协议上,由IBM在1999年发布(由 IBM 的 Andy Stanford-Clark 和 Arcom 的 Arlen Nipper 为了一个通过卫星网络连接输油管道的项目开发,之后 IBM 一直将 MQTT 作为一个...
PIL(Python Image Library),基于Python的图像处理库,功能强大,对图形文件的格式支持广泛,内置许多图像处理函数,如图像增强、滤波[算法]等Pillow,图像处理库,PIL图像库的分支和升级替代产品。Matplotlib,著名的绘图库,提供了整套和matlab相似的命令API,用以绘制一些高质量的数学二维图形,十分适合交互式地进行制图。brewer2...

queuelib Queuelib is a Python library that implements object collections which are stored in memory or persisted to disk, provide a simple API, and run fast. Queuelib provides collections forqueues(FIFO),stacks(LIFO), queues sorted by priority and queues that are emptied in around-robinfashion...
asynchronous communication. When an email is sent, the sender continues to process other things without needing an immediate response from the receiver. This way of handling messagesdecouplesthe producer from the consumer so that they do not need to interact with the message queue at the same ...
In addition to alternative list implementations, the library also offers other tools such as the bisect module with functions for manipulating sorted lists:>>> >>> import bisect >>> scores = [(100, 'perl'), (200, 'tcl'), (400, 'lua'), (500, 'python')] >>> bisect.insort(scores...
These are code samples that show common scenario operations with the Azure Storage Queue client library. The async versions of the samples (the pytho...
