eval(expression[,globals[,locals]])exec(expression[,globals[,locals]])'''用法基本相似,expression执行表达式,globals全局变量(必须字典),locals局部变量(任意mapping object,一般是字典)不同点:eval将表达式计算出来,结果返回,不会影响当前环境exec将表达式作为py语句运行,可以进行赋值等操作(题目中不常见)eval 与 ...
getattr(object, name[,default]) 通过name返回object的属性值。当属性不存在,将使用default 返回,如果没有default,则抛出AttributeError。name必须为字符串 setattr(object, name, value) object的属性存在,则覆盖,不存在,新增 hasattr(object, name) 判断对象是否有这个名字的属性,name必须为字符串 代码示例:接下来...
