Pythonrandom module common methods

This article mainly introduces the commonly used methods of the Pythonrandom module. This article lists the most commonly used methods. if you need a friend, refer to the following code:

import randomprint random.random()

Obtains a floating point number smaller than 1.

The code is as follows:

import randomrandom.randint(1,10)

Returns an integer from 1 to 10.

The code is as follows:

import randomprint random.uniform(0,2)

Obtains a floating point number greater than 0 and less than 2.

The code is as follows:

import randomprint random.randrange(1,10,4)

Obtain a random number ranging from 1 to 10 in step 4.

The code is as follows:

import randoma=[1,2,3,4,5]random.choice(a)

Extracts an element from list a at random.

The code is as follows:

import randoma=[1,2,3,4,5]random.shuffle(a)

Disrupt the order of elements in List

The code is as follows:

import randoma=[1,2,3,4,5]random.sample(a,3)

Three elements can be retrieved from list a in a random order (one element can only be retrieved once, so the number of retrieved elements cannot be greater than the number of elements contained in the list)
