(equivalent to cloning two sub-processes in a parent process)5, within a process can communicate between threads. Two processes want to communicate, must be implemented through an intermediary agent 6, creating a new thread is simple, creating a new process requires cloning its parent process. 7. A thread can control or manipulate other threads within the same process. However, a process can only manipulate child processes. 8, the parent process can be modified without affecting the child proce

File mode:The mode of opening the file is: R, read-only mode (default). W, write-only mode. "unreadable; not exist; create; delete content;" A, append mode. "Readable; not exist" create; "only append content;" "+" means you can read and write a file at the same time r+, can read and write files. "readable; writable; can be added" w+, write and read. "Create a new file, populate the content." Equivalent to overwrite " A +, with a "U" means that the \ r \ n \ r \ \ \ \

manipulate them? Here's how the For loop works:In fact, before processing this data, the for loop calls the __iter__ () method, converts the data into an iterative object , and then calls the __next__ () method of the iterated object , and Capturing the stopiteration exception will end up traversing all the data and will not throw the exception.#simulating A For loop with a while loopNum_list = [1,2,3,4]#the __iter__ () method of the data is called first to generate an iterative objectlist_ite

# This article mainly describes the Python reference module and Python lookup module path of the relevant information, the need for friends can refer to the followingThe mutual independent reference between modules is the basic ability of any programming language. The word "module" may be different in various programming languages, but we can simply assume that a

Then import in main.py:After the module is introduced, we can invoke the object in the module, including functions and global variables, by means of the module.Python also has a few other useful ways to import:Rename Module Name: Specifies that only specific objects in the module are imported and can be accessed directly, as is the case with global objects in main.py:(Because the function move is o

and then wake the thread. NPTL is also a 1 *1 line libraries, that is, when you use the Pthread_create () call to create a thread, a scheduler entity is created in the kernel accordingly. In Linux it is a new process, and this method is most likely to simplify the implementation of the thread. There is also a m*n model in addition to the NPTL 1 model, which typically has more user threads than the kernel's scheduler entity. In this implementation, the line libraries itself must deal with the

dependencies between modules. Each programming language has certain conventions for module and package management, and without understanding these conventions, it can be a hindrance to learning this language. Now I'd like to comb through these conventions of python. One, the path of the Python lookup module To run a Python
