在Python中,String(字符串)、Integer(整数)、Floating-point(浮点数)均为内置数据类型(分别为`str`、`int`、`float`)。而Array(数组)需要借助`array`模块实现,并不属于内置数据类型。需要注意的是,Python内置的列表(`list`)功能与数组类似,但名称不同且直接可用,而数组需要额外导入模块。因此正确答案为**c) Arr...
Python provides a variety of built-in data types.In Python, since everything is an object, data types are actually classes; and the variables are instances of the classes.A data type defines the type of a variable and allows us to store and manipulate different kinds of data. In Python, ...

This tutorial will go through a few of the built-in functions that can be used with numeric data types in Python 3. Becoming familiar with these methods can …
Strings in Python are sequences. This single fact should be enough to include them in the section covering other container types, but they differ from other container types in one important detail. Strings have very specific limitations on what type of data they can store, and that is Unicode...
