Code like a pythonista:idiomatic PythonIf you have a C + + foundation, it is relatively easy to learn another language. Because C + + is process oriented and object oriented. It is very low level, can access the machine like C, it is also very advanced, there are templates, STL and so on. If I read the deep C + + object model carefully, I think other languages will not be more complicated than this. The more you know about C + +, the more

This project is my first complete Python Web project, and for beginners, this project is definitely a great practiced hand project.The name is still difficult, but it is really annoying to enter such long names (phone address book QR code generation site) to define the site, so give this project a name, what is it called? It's called "Goose Day Directory" (Earth address list).-------------------------------
This article mainly introduces how to create a Python module and import a module. it analyzes the definition, import, and usage skills of the module attributes, and illustrates the concept and usage of the package, for more information about how to create a Python module and how to import a module, see this article. The example analyzes the module definition, how to import and how to use Module attributes,
Sometimes a Python program runs and it takes a long time to run. You may want to improve the efficiency of the program. Then what should I do?First you need to find out where the program bottlenecks are-for example, which function takes longer to run? Which function consumes more memory, does it need to optimize the use of memory? Which CPU time takes longer? etc... These need to be considered, Python has
