understand computer knowledge, psychology and philosophy. Artificial intelligence consists of a very wide range of sciences, consisting of a variety of fields, such as machine learning, computer vision, and so on, in general, one of the main goals of AI research is to make machines capable of doing complex work that normally requires human intelligence. But different times, different people's understanding of this "complex work" is different. In Dece

Python was invented by Dutch Guido von Rossum, and the first python was developed by C language, invoking C's class library, with features such as classes, functions, exception handling, tables, and dictionaries.Python has a high level of extensibility, and later in the Guido von Rossum led the beginning of continuous expansion, while the performance of the computer, gradually formed a community, in all wal

So what if you want to copy exactly one copy instead of quoting Shoplist?MyList = shoplist[:]Complete exampleslicing (Slice)Yesterday suddenly noticed the sequence of slices in front and back. Try it out, if it's a range of [3:2], then output an empty list. Of course [2:-1] This is no problem, 1 is me

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
