random.random

`random.random()` 是 Python 中的一个函数，它可以生成一个 0 到 1 之间的随机浮点数。具体实现可以参考以下示例代码：

import random

print(random.random())  # 输出一个 0 到 1 之间的随机浮点数

需要注意的是，每次运行程序时生成的随机数都可能不同，因为它是根据计算机当前时间等因素生成的。

random.Random.randint

random.Random.randint 是一个方法，用于生成指定范围内的随机整数。

你可以使用以下代码来调用 random.Random.randint 方法：

import random

# 创建 Random 对象
rand = random.Random()

# 生成随机整数
random_number = rand.randint(start, end)

在上面的代码中，`start` 和 `end` 是表示范围的整数。`randint` 方法将返回一个介于 `start` 和 `end` 之间（包括两者）的随机整数。

请注意，每次调用 `randint` 方法时，都会生成一个新的随机数。

python random.Random

The random.Random class in Python is used to generate random numbers. It is a pseudorandom number generator that uses a deterministic algorithm to generate a sequence of numbers that appear to be random. The class provides methods to generate random numbers of different types, such as integers, floats, and boolean values. It also allows you to set the seed value to generate the same sequence of random numbers every time you run the program.

Here is an example of how to use the random.Random class to generate a random integer between 1 and 100:

import random

# create a new instance of the Random class with a seed value of 42
rng = random.Random(42)

# generate a random integer between 1 and 100
random_int = rng.randint(1, 100)

print(random_int)

In this example, we first import the random module and create a new instance of the Random class with a seed value of 42. We then use the `randint()` method of the `rng` object to generate a random integer between 1 and 100. Finally, we print the generated random integer. Since we have set the seed value to 42, we will always get the same random integer when we run this program.
