python隨機數，隨機選擇……random

import random
from random import random, uniform, randint, randrange, choice, sample, shuffle

list = ['jack', 'rose', 'tom', 'jerry']
print(random())  # 隨機小數 0.0 <= x < 1.0
print(uniform(1, 10))  # 隨機小數 x, 1.0 <= x < 10.0
print(randint(1, 10))  # 隨機整數 1 to 10, endpoints included
print(randrange(0, 101, 2))  # 隨機0-101，步進2，也就是偶數
print(randrange(0, 101, 5))  # 隨機0-101，步進5，也就是5的倍數
print(choice('abcdefghij'))  # 隨機字符串中的一個字符
items = [1, 2, 3, 4, 5, 6, 7]
print(items)
shuffle(items)  # 重新隨機排序
print(items)
print(sample([1, 2, 3, 4, 5], 3))  # 隨機選3個
