In ArrayList, it mainly provides

best practices are still being developed.Looking to the futureNow we have learned about all aspects of deferreds and the core concepts behind twisted. This means that we have nothing to introduce, because the rest of twisted mainly includes specific applications such as network programming or asynchronous database processing. So, in the next section, we want to take a detour and see the other two using asynchronous i/ O's system is similar to what twisted has in mind. Then, at the end, we'll ma

by jquery). nbsp; 18. Combining jquery and JavaScript native code when necessary as described above, jquery is JavaScript, which means that what you can do with jquery can also be done with native code. Native code (or vanilla) may be less readable and maintainable than jquery, and the code will be longer. But also means more efficient (usually closer to the underlying code, the more readable, the higher the performance, for example: The assembly, of course, the need for more powerful people ca

There are also high-level packages in the Python standard library, such as socketserver,simplehttpserver,cgihttpserver,cgi.These are all packages that help us to use the socket more easily. If you already know the socket, these packages are easy to understand.
