有没有用Python生成n个不重复随机坐标的算法？比如范围（5，3）内的坐标：1 21 32 22 3等等
业精于勤，荒于嬉;行成于思，毁于随。
python 3
import itertools list(itertools.product(range(1, 6), range(1, 4)))
If randomization is needed, just randomly generate the index in the above list
import random n = 5 random_list = list(itertools.product(range(1, 6), range(1, 4))) random.sample(random_list, n)
import random n = 5 for x in random.sample(range(3 * 5), n): print('({}, {})'.format(*pmod(x, 3)))
