使用random库.

EX:

>>> import random
>>> random.randint(100, 999)
563

如果是整数，random.randint(100,999)，如果是浮点数，大概只能自己用random.random()生成了。

他的意思可能是像密码锁那样的，三位数。。。。。每个都是从0-9
不是我们理解的数学上的三位数。。。。

如果是要生成字串可以这样:

>>> ''.join(random.sample(['0','1','2','3','4','5','6','7','8','9'], 3))
'713'
>>> ''.join(random.sample(['0','1','2','3','4','5','6','7','8','9'], 3))
'579'
>>> ''.join(random.sample(['0','1','2','3','4','5','6','7','8','9'], 3))
'328'

random.sample只能进行不重复取样，所以取不出‘001’

那还可以从1-999，然后转为字符串，前面补0就行了。

如果要生成001，可以用 format = lambda i: "03d" %i

这个方法不错
result = ('%d'%random.randint(0,999)).rjust(3,'0')
