Python随机值生成的常用方法总结_python

import random
#1、随机整数：包含上下限：[a, b]

for i in range(10): print(random.randint(0,5),end=" | ")

import random

#2.随机整数：不包含上限：[a, b）

for i in range(10): print(random.randrange(0,5),end=" | ")

#3.随机选取指定范围内（指定基数）递增集合中的随机数
for i in range(10): print(random.randrange(0,10,2),end=" | ")
print()
for i in range(10): print(random.choice(range(0,10,2)),end=" | ")

#4 0-1之间的随机浮点数
for i in range(10): print(random.random())

#5.随机浮点数
for i in range(10): print(random.uniform(1,10),end="|")
print()
for i in range(10): print(random.uniform(10,1),end="|")

#6.随机字符
for i in range(10):  print(random.choice('abcdefghijklmnopqrstuvwxyz!@#$%^&*()'),end="|")
print()
for i in range(10):  print(random.choice("helloworld"),end="|")
print()
for i in range(10):  print(random.choice(["python", "java", "c", "c++", "golang"]),end="|")
print()
for i in range(10):  print(random.choice(("js", "python", "ruby")),end="|")

#7.多个字符中生成指定数量的随机字符,返回数组格式
print(random.sample('abcdefghijklmnopqrstuvwxyz',5))

str = ''.join(random.sample('abcdefghijklmnopqrstuvwxyz',5))
print(str)

import random
print(random.uniform(1, 10))

import random
print(random.gauss(5, 1))  #(均值为 5， 标准差为 1)

import random
print(random.expovariate(0.2))
