is called, and the asynchronous invocation is a mechanism similar to a message or event, but it is called in the opposite direction. The service of an interface notifies the client (that is, the interface that invokes the client) when it receives a message or an event occurs. Callbacks are very closely related to asynchronous calls, and we typically use callbacks to register asynchronous messages and to implement notification of messages through asynchronous calls. Synchronous calls are the sim

Example of implementing JSON deserialization Class Object in Python, json serialization Our network protocol is generally to convert data into JSON before transmission. Previously, serialization and deserialization were implemented in Java, both jackson and fastjson are very simple. Now there are projects that need to be developed using Python. it is natural to e

The examples in this article describe the use of sys.argv parameters in Python. Share to everyone for your reference. The specific analysis is as follows: In the process of learning Python, I never understood the meaning of sys.argv[], though I knew it was a command line argument, but it was a bit of a blur. Today, a good study of a, finally is Taichetaiwu. Sys.argv[] is used to get command line arguments,

What is the concept of a module in python? Can I use a simple example? A module is a file, and the imported file is imported into the corre

Python local and global namespace usage example This example describes the usage of local and global namespaces in Python. Share it with you for your reference.

Remote calls make it possible to invoke objects, methods of the remote server in exactly the same way as local objects, methods, because we have hidden them through network programming. Remote invocation is the foundation of a distributed system. Remote calls are generally divided into two types, remote procedure call (RPC), and remote method call (RMI). Rpc RPC is a function-level remote invocation, which transmits data mostly over HTTP, in the form of XML, JSON, serialized data, and so on.

Python uses MD5 to encrypt the string, for example, pythonmd5 There are several Python encryption modules, But no matter which encryption method you use, you need to first import the corresponding encryption module and then use the module to encrypt the string. Import the required md5 encryption module first:Copy codeThe Code is as follows:Import hashlibCreate an
