在Python里,每种数据类型都有自己默认自带的函数、方法以及变量,要查看某一数据类型本身具有的函数、方法和变量,可以使用dir()这个函数,这里以字符串和整数为例,举例如下: >>>dir(str)['__add__','__class__','__contains__','__delattr__','__doc__','__eq__','__format__','__ge__','...

Python is a dynamically typed language, meaning the variable type is determined by the data assigned to it. In the previous examples, the x, y, and z variables are integer types, capable of storing positive and negative whole numbers.
