Python随机数与随机字符串详解
随机整数:>>>importrandom>>>random randint(0,99)21随机选取0到100间的偶数:>>>importrandom>>>random randrange(0,101,2)42随机浮点数
随机整数:
|
1
2
3
|
>>> import random>>> random.randint(0,99)21 |
随机选取0到100间的偶数:
|
1
2
3
|
>>> import random>>> random.randrange(0, 101, 2)42 |
随机浮点数:
|
1
2
3
4
5
|
>>> import random>>> random.random() 0.85415370477785668>>> random.uniform(1, 10)5.4221167969800881 |
随机字符:
|
1
2
3
|
>>> import random>>> random.choice('abcdefg&#%^*f')'d' |
多个字符中选取特定数量的字符:
|
1
2
3
|
>>> import randomrandom.sample('abcdefghij',3) ['a', 'd', 'b'] |
多个字符中选取特定数量的字符组成新字符串:
|
1
2
3
4
5
|
>>> import random>>> import string>>> string.join(random.sample(['a','b','c','d','e','f','g','h','i','j'], 3)).replace(" ","")'fih' |
随机选取字符串:
|
1
2
3
|
>>> import random>>> random.choice ( ['apple', 'pear', 'peach', 'orange', 'lemon'] )'lemon' |
洗牌:
|
1

4
5
|
>>> import random>>> items = [1, 2, 3, 4, 5, 6]>>> random.shuffle(items)>>> items[3, 2, 5, 6, 4, 1] |
random的函数还有很多,此处不一一列举,
不努力,谁会可怜你?
