Python全局列表 [英] Python global lists

问题描述

我正在学习python，并且在全局变量/列表方面遇到了问题.我正在写一个基本的河内手册塔程序，这是当前的程序:

I'm learning python, and am having a problem with global variables/lists. I'm writing a basic manual tower of hanoi program, here's the program currently:

pilar1 = [5,4,3,2,1,0]
pilar2 = [0,0,0,0,0,0]
pilar3 = [0,0,0,0,0,0]

def tower_of_hanoi():

    global pillar1
    global pillar2
    global pillar3

    print_info()

def print_info():

    global pillar1
    global pillar2
    global pillar3

    for i in range(4,-1,-1):
        print(pillar1[i], " ", pillar2[i], " ", pillar3[i])

我尝试了一些变体，但是每次遇到错误"NameError:未定义全局名称'pillar1'".

I've tried a few variations, but every time I got the error "NameError: global name 'pillar1' is not defined".

在此设置下处理全局列表的最佳方法是什么?如果可能的话，我宁愿只使用一个源文件.谢谢！

What would be the best way to handle a global list in this setting? I'd prefer to just use one source file, if possible. Thanks!

推荐答案

这是因为您已将其声明"为pilar1，而不是pillar1

It's because you've "declared" it as pilar1, not pillar1
