+`Python`的`random`模块用于生成伪随机数以及执行随机操作，它提供了多种方法可以处理随机数、随机选择、打乱序列。
+
+## 1. 生成随机数
+
+### 随机浮点数
+
+- **`random()`**: 生成一个`0`到`1`之间的随机浮点数(左闭右开区间) 
+```python
+>>> import random as r
+>>> print(r.random())
+```
+
+- **uniform(a, b)**: 生成一个范围在`[a, b]`的随机浮点数
+```python
+>>> print(r.uniform(10, 20))
+```
+
+### 随机整数
+
+- **randint(a, b)**： 生成一个范围在`[a, b]`的随机整数
+```python
+>>> print(r.randint(1, 10))
+```
+
+- **randrange(start, stop, step)**: 从指定的范围内，按步长返回一个随机整数
+```python
+>>> print(r.randrange(1, 10, 2))
+```
