尝试：
from random import randint
print(randint(0, 9))更多信息： https ： //docs.python.org/3/library/random.html#random.randint
import random
print(random.randint(0,9))random.randint(a, b)返回一个随机整数 N，使得 a <= N <= b。
文档： https ： //docs.python.org/3.1/library/random.html#random.randint
试试这个：
from random import randrange, uniform
# randrange gives you an integral value
irand = randrange(0, 10)
# uniform gives you a floating-point value
frand = uniform(0, 10)
