隨機整數:
>>> import random
>>> random.randint(0,99)
21
隨機選取0到100間的偶數:
>>> import random
>>> random.randrange(0, 101, 2)
42
隨機浮點數:
>>> import random
>>> random.random()
0.85415370477785668
>>> random.uniform(1, 10)
5.4221167969800881
隨機字元:
>>> import random
>>> random.choice('abcdefg&#%^*f')
'd'
多個字元中選取特定數量的字元:
>>> import random
random.sample('abcdefghij',3)
['a', 'd', 'b']
多個字元中選取特定數量的字元組成新字串:
>>> import random
>>> import string
>>> string.join(random.sample(['a','b','c','d','e','f','g','h','i','j'], 3)).r
eplace(" ","")
'fih'
隨機選取字串:
>>> import random
>>> random.choice ( ['apple', 'pear', 'peach', 'orange', 'lemon'] )
'lemon'
洗牌:
>>> import random
>>> items = [1, 2, 3, 4, 5, 6]
>>> random.shuffle(items)
>>> items
[3, 2, 5, 6, 4, 1]
random的函數還有很多,此處不一一列舉,
