确定Python变量是否是内置类型的实例 [英] Determine if Python variable is an instance of a built-in type

问题描述

我需要确定给定的Python变量是否是本机类型的实例:str，int，float，bool，list，dict等.有优雅的方法吗?

I need to determine if a given Python variable is an instance of native type: str, int, float, bool, list, dict and so on. Is there elegant way to doing it?

或者这是唯一的方法:

if myvar in (str, int, float, bool):
    # do something

推荐答案

实现此目的的最佳方法是在称为primitiveTypes的元组列表中收集类型，并且:

The best way to achieve this is to collect the types in a list of tuple called primitiveTypes and:

if isinstance(myvar, primitiveTypes): ...

types模块包含所有有助于构建的重要类型的集合列表/元组.

The types module contains collections of all important types which can help to build the list/tuple.

从Python 2.2开始可以正常工作
