python random.random

`random.random()` 是 Python 中 random 模块中的一个函数，用于生成一个在 0 到 1 之间的随机浮点数。其用法为：

import random

num = random.random()

print(num)

输出结果为一个在 0 到 1 之间的随机浮点数。

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.

pythonrandom.random

Python的random模块中的random.random()函数用于生成一个0到1的随机浮点数，范围包括0，但不包括1。这个函数每次被调用时会返回一个随机的浮点数。 这个函数的使用方法如下：

import random
print(random.random())

以上代码将会打印出一个在0到1之间的随机浮点数。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
