PyWebIO Write interactive web app in script way.

Shell IO

Take Input on Termianl

Let’s begin with input directly on terminal. Open a terminal on your system and type:

read x 

Here read is the Linux command and “x” is the variable, where input value will be stored.

Hit enter after typing the above command. You will see a blank line without a prompt. It means the shell is waiting for your input. Type some text and hit enter button. You will find the prompt again.

Now, verify that the input value is stored in a defined variable. To confirm it, print the variable value with the echo command.

echo $x

There is no need to define any data type for variables. Shell automatically adjusts the type based on the user input.

Lets’ go with a sample shell script to take user input.

调用python函数的方式，获取用户输入 和 输出到浏览器。（体验类似 shell ）

构建简单的web应用 或者 基于浏览器的 GUI 应用， 不需要HTML JS知识。

PyWebIO provides a series of imperative functions to obtain user input and output on the browser, turning the browser into a "rich text terminal", and can be used to build simple web applications or browser-based GUI applications without the need to have knowledge of HTML and JS. PyWebIO can also be easily integrated into existing Web services. PyWebIO is very suitable for quickly building applications that do not require complex UI.

特征：

• 同步模式读取输出
• 布局内置，不用设置
• 更少的入侵， 修改已有代码，只需要关注输入和输出的替换，可完成代码改造
• 支持继承到已有web框架
• 支持 异步 和 协程
• 支持数据可视化

Features：

• Use synchronization instead of a callback-based method to get input
• Non-declarative layout, simple and efficient
• Less intrusive: old script code can be transformed into a Web application only by modifying the input and output operation
• Support integration into existing web services, currently supports Flask, Django, Tornado, aiohttp, FastAPI framework
• Support for asyncio and coroutine
• Support data visualization with third-party libraries, e.g., plotly, bokeh, pyecharts.
