在将 Python 2.7 转换为 3.4 后，如何将 [x][y] 浮点数转换回整数。格式化为浮点数
前任。self.table[x][y] 转换成一个整数来获取 x 和 y 值。
我得到的错误
return self.table[x][y].physics_module
TypeError: list indices must be integers, not float
我试过的
我知道将 (x) 转换为整数的方法，如 int(x) 或 5 / 3 转换为 5 //3 等。这在过去的所有其他时间都有效，到目前为止我遇到了问题。有类似的问题，但这些答案在这种情况下不起作用TypeError: integer argument expected got float' Python 3.4我尝试了这些方法，因为这也是我的问题。
我正在将 python 3.4 与 pygame 一起使用，这对于本示例可能无关紧要
我正在尝试做的事情：
目标是将教程从 python 2.7 转换为 python 3.4 以使用 python 3.4 理解它。我跑了 2to3.py 看看它是否也能正常工作。
