好的，我理解您需要将 ...

这些输出是程序在每次鼠标移动时，对棋盘上所有可能的落子位置调用了 `can_move` 函数进行合法性判断，目的是**为可移动位置高亮或为AI计算走法做准备**。您感觉“没用”是因为输出太多刷屏了，而且没有关键信息。

### 这些输出如何帮助学习？
- 您可以看到每个位置是否被判定为合法（如果 `can_move` 返回 `True` 或 `False`，但当前代码只打印了调用，没有显示结果）。
- 通过对比您自己知道的规则，可以判断 `can_move` 的执行是否正确。例如 `(3,8)` 是黑方某棋子，如果禁止它移动到 `(4,0)`，说明规则起作用了。
- 但大量输出确实干扰正常游戏，所以建议**只保留必要打印**。

### 如何修改代码以减少输出？
找到输出这些信息的地方（通常是AI循环或鼠标事件处理），将 `print("can_move called: from ...")` 注释掉或替换为条件打印（例如只在调试模式开启时才输出）。下面是一个示例修改：

# 将原来的 print 行替换为：
# debug = False # 全局变量，只在需要调试时设为 True
if debug:
print("can_move called: from ({},{}) to ({},{})".format(r1, c1, r2, c2))

复制代码

或者直接删除该行，保留 `can_move` 内部的合法/非法判断输出。这样你就只会在移动非法时看到错误信息。

### 更实用的调试方式：添加关键事件输出
在 `on_click` 等关键函数中添加输出，比如：
- “您选中了 (行,列) 的棋子”
- “移动成功：从 (x1,y1) 到 (x2,y2)”
- “吃掉了对方的某棋子”
- “将军！请应将”

这样既能了解程序运行流程，又不会刷屏。

### 提供一个精简版完整代码（无多余 print，含棋谱）
由于您的 Python 版本是 3.4，下面给出一个**可直接运行**的代码，去除了所有 `can_move` 调用打印，只保留关键的走棋提示和棋谱显示。代码包含：
- 汉字棋子、鼠标点击走棋、红方（您）vs 黑方（随机AI）
- 将军检测、不能自将、不能斜走将帅、兵卒不能后退
- 悔棋按钮、棋谱列表显示（使用 Listbox）

您复制到 `chess_final.py` 并运行即可。

### 如何使用？
1. 将以上代码复制，保存为 `chess_final.py`。
2. 在命令行执行 `python chess_final.py` 或双击文件运行。
3. 红方（您）点击己方棋子再点击目标格子即可走棋，黑方自动应战。
4. 右侧面板显示棋谱，点击“悔棋”可撤回上一步（您和黑方各一步）。
5. 游戏结束时会弹出询问是否重新开始。

这段代码**已经去掉了所有多余的调试输出**，只保留关键状态信息。如果您还想学习函数调用流程，可以在 `can_move` 函数开始添加一行条件打印，例如：

if debug:
print("can_move called: from ({},{}) to ({},{})".format(r1, c1, r2, c2))

复制代码

并将 `debug` 设为 `False` 关闭，需要时改为 `True` 观察。祝您学习愉快！
