这和 Python 内置的 string 标准库中 Template 类的 substitute()模板方法一样存在着同样的安全隐患，所以使用 safe_substitute()来替代是一样的道理。如我们现在将之前的一些配置信息写入 config.yaml 文件中：mysql:host: "127.0.0.1" port: 3306 user: "root" password: "123456" database: "test"...
def functionname( parameters ): "函数_文档字符串" function_suite return [expression]默认情况下，参数值和参数名称是按函数声明中定义的顺序匹配起来的。实例：以下为一个简单的Python函数，它将一个字符串作为传入参数，再打印到标准显示设备上：#!/usr/bin/python # -*- coding: GBK -*- def printme( ...
