1. Statements are executed on a line-by-row basis, unless you do not writeIf the statement uses an if statement, his execution is jumping, and the IF statement is the process control2. Automatic boundary detection of blocks and statementsBecause Python does not have curly braces for these bounding symbols, it uses code indentation to control boundariesSimilarly, the end of a statement is not using semicolons, but also using code indentationIn the above example, for the indentation before the for

role: This function is mainly for the purpose of serialization objects. Maybe some people are allergic to the word serialization, my understanding is very simple. This means converting the type of the object to a string type (or, more specifically, the JSON type). It's so simple. For example, you have a class, so you can convert it to the corresponding JSON type by this method. It's simple.Then look.Syntax:Json.stringify (value [, Replacer] [, space])Value: is the required field. Is the object y

the Python standard library.1) Network application based on socket layerSockets are the bottom line of the Network Programmability section. With the socket package, we can manage the socket directly, such as assigning a socket to a port, connecting a remote port, and transferring data over a connection. We can also use the Socketserver package to build servers more easily. With multi-threaded and multi-process coordination, the establishment of multi-threaded or multi-process server, can effect

So this involves a recursive invocation of something.Here is a deep copy function I implemented, you can write your own and then add to your own node.
