变量是编程语言中用于存储数据的一种方式。在教程中,我们将学习如何声明和使用变量。

声明变量

声明变量通常涉及指定变量名和数据类型。以下是一个简单的例子:

x = 10

在这个例子中,x 是一个整数类型的变量,它存储了值 10

使用变量

使用变量很简单,只需在需要的地方引用变量名即可:

print(x)

这将输出 10

数据类型

Python 支持多种数据类型,如整数、浮点数、字符串等。以下是一些常见的数据类型:

  • int:整数
  • float:浮点数
  • str:字符串

例如:

name = "Alice"
age = 25
height = 1.75

# Variables Introduction

Variables are a way to store data in programming languages. In this tutorial, we will learn how to declare and use variables.

## Declaring Variables

Declaring a variable typically involves specifying a variable name and a data type. Here is a simple example:

```python
x = 10

In this example, x is an integer variable that holds the value 10.

Using Variables

Using variables is straightforward; you simply reference the variable name where needed:

print(x)

This will output 10.

Data Types

Python supports various data types, such as integers, floats, strings, and more. Here are some common data types:

  • int: Integer
  • float: Floating-point number
  • str: String

For example:

name = "Alice"
age = 25
height = 1.75
