引用函數庫

以random為列
import random
print(random.random())
print(random.randint(1,9))       #取1到9之間的整數
print(random.randrange(1,9))   #取1到8之間的整數
print(random.choice("I am very tired"))  #取字串內 隨機的一個字
print(random.choice(["I","am","very","tired"]))  #取list 內任一個元素

===================

fruits=["apple","banana","cherry","mellon""orange","pinapple"]
print(random.shuffle(fruits))
print(random.choice(fruits)) #隨機抽list 的一個元素
print(fruits)
random.shuffle(fruits) #將list fruits 內的元素 隨機排列
print(fruits)

  結果是

 None

apple
['pinapple', 'mellonorange', 'apple', 'cherry', 'banana']
['banana', 'cherry', 'mellonorange', 'pinapple', 'apple']

    ====================

使用seed() 將亂數重整

import random
random.seed()
for i in range(1,9):
    print(random.randint(1,9))

============

import 指令

如

  import tkinter as tk

  from random import randint
