我正在处理一个递归函数，以显示零周围任何空格的内容。我收到类型错误＆＃34; TypeError：不支持的操作数类型 - ：＆＃39; list＆＃39;和＆＃39; int＆＃39;＆＃34;为我的代码。我希望这个代码（当给定一个位置时）显示它周围的任何空间，直到有一个数字，这些空间不会被挖掘。

答案 0 :(得分：1)
在函数 mineCascade 中，您可能会出现语法错误，可能是第29行，如回溯所示。变化
if (r > 0) and (c < len(m[0]-1)):
到
if (r > 0) and (c < len(m[0])-1):
由于operator precedence，很多括号都是不必要的，可以简化为：
if r > 0 and c < len(m[0]) - 1:
多余的括号可能是你隐藏错误的原因。
