demo2

from rich.console import Console

console = Console()
test_data = [
    {"jsonrpc": "2.0", "method": "sum", "params": [None, 1, 2, 4, False, True], "id": "1",},
    {"jsonrpc": "2.0", "method": "notify_hello", "params": [7]},
    {"jsonrpc": "2.0", "method": "subtract", "params": [42, 23], "id": "2"},
]

def test_log():
    enabled = False
    context = {
        "foo": "bar",
    }
    movies = ["Deadpool", "Rise of the Skywalker"]
    console.log("Hello from", console, "!")
    console.log(test_data, log_locals=True)

#注意其中的log_locals参数会输出一个表格，该表格包含调用 log 方法的局部变量。
# log 方法既可用于将长时间运行应用程序（例如服务器）的日志记录到终端，也可用于辅助调试。
test_log()

console = Console()

table = Table(show_header=True, header_style="bold yellow") #show_header是否显示表头，header_style表头样式
table.add_column("Date", style="dim", width=12) #添加表头列
table.add_column("Title")
table.add_column("Production Budget", justify="right")
table.add_column("Box Office", justify="right")
table.add_row( #添加行
    "Dev 20, 2019", "Star Wars: The Rise of Skywalker", "$275,000,000", "$375,126,118"
)
table.add_row(
