The most difficult thing to understand is that generator is not the same as the process of executing a function. The function is executed sequentially, the return statement is encountered, or the last line function statement is returned. The function that becomes generator, executes at each call to next (), encounters a yield statement return, and execute

If you have decided to use Python as your programming language, the next question in your mind will be: "What Python libraries are available for data analysis?"

N-dimensional arrays, a fast and efficient multi-dimens

). Of course, I do not exclude a developer to master the use of a variety of development tools, I think, when we learn programming to a stage, the concept of programming has a basic understanding, and have good programming habits and learning methods, this time to learn other development tools is not too late, And the difficulty of adapting to these development tools will be greatly reduced. Vi. How do I
