In addition to user interface navigation, your App may also need to support interactive operations in some context. For example, adding two or three identical operation buttons to all the content will often cause interface interference: in many feeds lists, we often see the comment, forward, and like buttons Under each feed ). Of course, buttons are very useful and easy to use, but it is very promis

, compared with other garbage collection methods, Python has obvious advantages in terms of real-time performance. Python's gc module is an open interface for management.
It is also easy to guess that the disadvantage is that the performance is relatively low. After reading this report, instagram has improved the performance by 10% by disabling the gc module!

When Python grew stronger, it was not right. After it became famous, there was a bit of wind. Some people say that i
estimated that a year can not be developed. High-level programming languages often provide a well-established codebase that you can invoke directly, for example, an SMTP library for an e-mail protocol, a GUI library for a desktop environment, developed on top of these existing code bases, and an e-mail client can be developed in a few days.Python provides us with a very well-established codebase, covering a wide range of content, such as networks, files, GUIs, databases, text, and so on, and is

Preface
I haven't written a blog post for a long time. I have been busy with my work recently. I am working on my own project a little bit of time, and I am working on the Android cool and practical open-source framework (UI framework) this article mentions many open-source UI frameworks. I
you can use to develop small web projects. Flask contains some reusable data communication modules commonly used in interactive website projects. It only needs a few lines of code, you can generate an interactive function.
7. Use Django to develop large projects
If you want to develop a complete web framework, try Django. Many ultra-large-scale websites such as Pinterests and Instagram are developed using Django.
8. Use Python to play with Apis

Because you cannot ultimately control the website you send the request, and you cannot guarantee that the site's response results will be the way you expected, and the site will always be normal.Here we provide two functions that can be used to handle errors:Curl_error ()-returns a string
