python Method Example for Generating Random Numbers Random Characters Random Strings

This paper is based on Windows 10 system environment, and realizes python to generate random numbers, random characters and random strings:

Windows 10 PyCharm 2018.3.5 for Windows (exe) python 3.6.8 Windows x86 executable installer

(1) Generate random numbers

Random integer

import random

num = random.randint(1, 50) #  Closed interval 
print(num)

Randomly choose even numbers between 0 and 100

import random

num = random.randrange(0, 101, 2) #  Left closed and right open interval 
print(num)

Random floating point number

import random

num = random.random() #  Generate 0-1 Random floating point number between 
num2 = random.uniform(1, 10) #  Generated random floating-point number reduction 1 Turn to an interval 1-10
print(num)
print(num2)

(2) Generate random characters

Random character

import random

alphabet = 'abcdefghijklmnopqrstuvwxyz!@#$%^&*()'
char = random.choice(alphabet)
print(char)

(3) Generate random strings

Generates a specified number of random strings

import random

alphabet = 'abcdefghijklmnopqrstuvwxyz!@#$%^&*()'
characters = random.sample(alphabet, 5)
print(characters)

Generates a specified number of random characters from a-zA-Z0-9

import random
import string

value = ''.join(random.sample(string.ascii_letters + string.digits, 8))
print(value)

Randomly select a string

import random

table = [' Scissors ', ' Stone ', ' Cloth ']
print(random.choice(table))
