Python 3.x 为什么我在这个随机游走测试中使用Python3得到了所有的单元一？

我是一个python初学者，我想知道为什么我在下面的脚本中得到了所有的单元。我希望得到一些1-10之间的整数

import random

def random_walk(n):
    """Return coordinates after 'n' block random walk"""
    x, y = 0, 0
    for i in range(n):
        (dx, dy) = random.choice([(0, 1), (0, -1), (1, 0), (-1, 0)])
        x += dx
        y += dy
        return (x, y)

for i in range(5):
    walk = random_walk(10)
    print(walk, "Distance from home = ",
         abs(walk[0]) + abs(walk[1]))

输出：

(1, 1) Distance from home =  2
(-1, 1) Distance from home =  2
(-3, 3) Distance from home =  6
(0, -2) Distance from home =  2
(1, 3) Distance from home =  4

（-1，0）与原点的距离=1
距原点的（-1,0）距离=1
距原点的（-1,0）距离=1
距原点的（-1,0）距离=1
（0，-1）距原点的距离=1

我认为这句话：

return (x, y)

应在循环之外：

import random

def random_walk(n):
    """Return coordinates after 'n' block random walk"""
    x, y = 0, 0
    for i in range(n):
        (dx, dy) = random.choice([(0, 1), (0, -1), (1, 0), (-1, 0)])
        x += dx
        y += dy
    return (x, y)

for i in range(5):
    walk = random_walk(10)
    print(walk, "Distance from home = ",
         abs(walk[0]) + abs(walk[1]))

输出：

(1, 1) Distance from home =  2
(-1, 1) Distance from home =  2
(-3, 3) Distance from home =  6
(0, -2) Distance from home =  2
(1, 3) Distance from home =  4

谢谢我刚想出来。
