python生成随机数、随机字符、随机字符串

本文是基于Windows 10系统环境，实现python生成随机数、随机字符、随机字符串：

• Windows 10

• PyCharm 2018.3.5 for Windows (exe)

• python 3.6.8 Windows x86 executable installer

---

(1) 生成随机数

• 随机整数

import random

num = random.randint(1, 50) # 闭区间
print(num)

• 随机选取0到100间的偶数

import random

num = random.randrange(0, 101, 2) # 左闭右开区间
print(num)

• 随机浮点数

import random

num = random.random() # 生成0-1之间的随机浮点数
num2 = random.uniform(1, 10) # 生成的随机浮点数归一化到区间1-10
print(num)
print(num2)

(2) 生成随机字符

• 随机字符

import random

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

(3) 生成随机字符串

• 生成指定数量的随机字符串

import random

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

• 从a-zA-Z0-9生成指定数量的随机字符

import random
import string

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

• 随机选取字符串

import random

table = ['剪刀', '石头', '布']
print(random.choice(table))
