python中随机数

 

1、抽取一个随机数

>>> import random
>>> random.randint(1,10)
3
>>> random.randint(1,10)
9
>>> random.randint(1,10)
3

 

2、从序列（列表、元组、字符串）中随机抽取一个元素

>>> test1 = ["aa","bb","cc","dd","ee"]
>>> test1
['aa', 'bb', 'cc', 'dd', 'ee']
>>> import random
>>> random.choice(test1)
'bb'
>>> random.choice(test1)
'bb'
>>> random.choice(test1)
'aa'
>>> random.choice(test1)
'dd'
