Preface Start TimeI learned C #2.0 and didn't fully learn it. After work, I am either busy with projects, or have a taste of various technologies, but I have no progress in language learning. It wasn't until six months ago that I started getting started with Python (purely a hobby, and I learned it intermittently) that I could do the same for programming!

Python crawler tutorial-elegant HTTP library requests (2) and pythonrequests Preface Urllib, urllib2, urllib3, httplib, and httplib2 are HTTP-related Python modules. If you look at the Python Module name, you will find it anti-human. What's worse, these modules are very different in Python2 and Python3, if the business code needs to be compatible with both 2 and 3, writing will crash. Fortunately, there is another amazing HTTP library called requests,

Because functional programming uses a completely different way of organizing programs, programmers who are used to using imperative examples may find functional programming a little hard to learn. In this article, you will learn some examples about how to use the functional style and use JavaScript to write good and elegant code. I will discuss:Function programming concepts include anonymous functions, different methods for calling functions, and meth

Elegant mobile development and client development For mobile development, in order to achieve the page HD effect, the specifications of visual drafts often follow the following two points: 1) Select the screen width and height of a mobile phone as the benchmark (for example, 375x667 of the iPhone 6 ). 2) for HD screens, in order to achieve high-definition effects, the canvas size of the visual draft will be twice that of the benchmark (for iPhone 6: T
