我是Python的初学者，正在制作一个棋盘游戏，让玩家输入他们想要向左/向右移动的位置等等。但是有时它会正确移动，有时它不会。我认为它与我的网格阵列有关，但我不确定......如果有人可以帮助我，那就太好了，谢谢！

我附上了我的所有代码，包括验证，以便用户不会逃离网格，因为我不确定要包含哪些部分以使我的问题和程序清晰。
答案 0 :(得分：2)
练习改进：
对调试here
进行了精彩的介绍我强烈建议使用增量编程：您写几行，确保它们正常工作，并且在您现有代码正确之前不要继续。这样，当某些东西不起作用时，你知道它在你添加的最后几行中。否则，你会得到200行代码，并且不知道错误所在的位置。
计划变更
此代码不是为调试或维护而设计的;你应该在继续之前解决这些问题。最重要的是，您创建了两组输入，用于执行一项任务（获取用户的移动），然后创建四组执行相同任务的代码（移动用户）。
相反，找到一些可用的措辞，让玩家在一个行上进入移动。您将其转换为移动坐标（例如[1，-2]为＆＃34;向上一个和左两个＆＃34;），然后使用单个代码块在网格中移动。不是测试四个代码块，而是测试一个;当你需要进行更改时，你可以进行一次更改，而不是在旋转和反射下进行四次复制。
<强>结果 您使用的代码应该更像这样：
def get_move():
advice = "Please enter your move in two integers:\n" +
"vertical, then horizontal. Use positive numbers\n" +
"for up and right, negative for down and left.\n"
example = "For instance, the line \n\t2 -1\n" +
" is 2 spaces up, one space left."
move = input(advice + example).split
x_move = int(move[0])
y_move = int(move[1])
# Here, you check move legality; repeat until you get a legal move
return x_move, y_move
while True:
print_board()
x_move, y_move = get_move() # get_move contains the input interaction and data checking
move(x_move, y_move) # perform the move; update the board.
另请注意，您应该更新现有的电路板，而不是（显然）为每次移动创建一个新电路板。保持这个循环直到游戏结束;不要在每一步都爆发。
这会让你走向解决方案吗？
