Rich 是一个 Python 库，可以在终端中提供富文本和漂亮、精美的格式。 使用 Rich API 可以很容易的在终端输出添加各种颜色和不同风格。 它可以绘制漂亮的表格，进度条，markdown，突出显示语法的源代码及回溯等等， 优秀的功能不胜枚举。
Rich 适用于 Linux，OSX 和 Windows。可与新的 Windows 终端一起使用， Windows 的经典终端仅限 8 种颜色。 Rich 还可以与 Jupyter NoteBook 一起使用，而无需其他配置。
安装说明
请选择以下任一种方式输入命令安装依赖：
Windows 环境 打开 Cmd (开始-运行-CMD)。
MacOS 环境 打开 Terminal (command+空格输入Terminal)。
如果用的是 VSCode编辑器 或 Pycharm，
可以直接使用界面下方的Terminal。
pip install richIn [1]:

from rich.console import Console
console = Console()
Console 对象含有一个 print 方法，
它的界面与 Python 内置的 print 功能相似，可以试试：
In [3]:
console.print("Hello", "World!")
Hello World!
可能已经料到，这时终端上会显示“ Hello World！”，
请注意，与内置的“打印”功能不同，Rich 会将文字自动换行以适合终端宽度。
有几种方法可以为输出添加自定义颜色和样式。
可以通过添加 style 关键字参数来为整个输出设置样式。例子如下：
In [4]:
console.print("Hello", "World!", style="bold red")
Hello World!
这个范例一次只设置了一行文字的样式。如果想获得更细腻更复杂的样式，
Rich 可以渲染一个特殊的标记，其语法类似于 bbcode。示例如下：
In [5]:
console.print("Where there is a [bold cyan]Will[/bold cyan] there [u]is[/u] a [i]way[/i].")
Where there is a Will there is a way.
Console 对象具有一个 log() 方法，
该方法具有与 print() 类似的界面，除此之外，
还能显示当前时间以及被调用的文件和行。
默认情况下，Rich 将针对 Python 结构和 repr 字符串进行语法突出显示。
如果记录一个集合（如字典或列表），Rich 会把它漂亮地打印出来，
使其切合可用空间。下面是其中一些功能的示例：

{"jsonrpc": "2.0", "method": "subtract", "params": [42, 23], "id": "2"},
]
In [8]:

console.log(test_data, log_locals=True)
