Question

我正在使用API在我的世界中使用python代码。我有两个柱子，一个瘦的，一个胖的，两个都有不同的大小。我试图将它们建在一个有点随机点的方形区域。我的所有代码都工作正常，直到底部。它运行第一个for循环发布“1 of 20 complete”但跳过第二个并将“2 of 20 complete”行发布到游戏聊天中。为什么它跳过第二个for循环？

from mcpi.minecraft import Minecraft
mc = Minecraft.create()
import random
import time

获得所有内容都围绕着的球员位置。

pos = mc.player.getTilePos()
x = pos.x
z = pos.z

我将方形区域（生物群系）分成多个列。这是第一次。其余的代码与此相同，但坐标位置略有不同。

#Make the first column of the biome
c = z -50
d = z -40
for i in range(-50, 0, 10):
    a = x + i
    b = x + (i + 10)
    biomex = random.randint(a, b)
    biomez = random.randint(c, d)
    pillar = random.randint(1, 2)
    if (pillar == 1):
        fat_pillar(random.randint(2, 6), 1)
    else:
        skinny_pillar(random.randint(2, 6), 1)
    time.sleep(0.5)
mc.postToChat("1 of 20 complete")
for i in range(50, 0, -10):
    a = x + i
    b = x + (i - 10)
    biomex = random.randint(a, b)
    biomez = random.randint(c, d)
    pillar = random.randint(1, 2)
    if (pillar == 1):
        fat_pillar(random.randint(2, 6), 1)
    else:
        skinny_pillar(random.randint(2, 6), 1)
    time.sleep(0.5)
mc.postToChat("2 of 20 complete")

它构建列的负坐标部分（第一个for循环）并将该行发布到聊天。然后它立即将第二行跳过第二个for循环（该列的正坐标部分）。我做错了什么？

Answer 1

所以我开始添加文本以显示所有类似建议的内容，并发现所有代码都能正常工作，甚至进入第二个循环的开始，直到biomex = random.randint(a, b)我之前添加的文本该行显示“得到了117，得到了b 107”。由此我意识到问题是a和b的排序。在第二个循环中，它使b为较低的数字，而较高的数字与第一个循环相反。因为它太工作所有我不得不做的是交换a和b，以便较低的数字是第一个而较高的数字是最后的biomex = random.randint(b, a)我认为奇怪的是python刚停止执行代码而没有显示我的错误信息。如果有的话，我可能早就注意到了。

python跳过我的第二个for循环
