我最近开始使用Python并且得到了一个赋值，我们应该在没有类的情况下使用现有代码并使用类和self.example变量重写它。
我决定使用在线发现的以下代码：

这段代码就像它应该的那样工作。这就是我设法改变它（我很可能不理解一些基本部分，这就是为什么它不起作用）。

基本上我所做的就是创建班级＆＃34;扫雷＆＃34;并制作＆＃34; numberofbombs＆＃34;和＆＃34; gridsize＆＃34;进入自我。参数。 起初我遇到的问题是每个＆＃34;例子（网格等）＆＃34;没看到他们现在在班里怎么样。在我将它们更改为＆＃34; Minesweeper.example（grid等）＆＃34;代码现在开始，因为它应该。
我得到的错误如下：
每当我放置＆＃34; Minesweeper。＆＃34;进入＆＃34; getneighbors（网格，*开始）＆＃34;它增加了6个位置参数，我似乎无法绕过它。
有谁知道如何解决这个问题，或者我是否从一开始就采取了错误的方式，以及为了修复代码需要做些什么？ 期待大家的帮助！
答案 0 :(得分：0)
你给它一个参数加上你解压缩大小为9的列表，总共10个
def f(*args):
print('received the following arguments:')
for arg in args:
print(arg)
foo = [1, 2, 5, 8]
f('sauce', *foo) # 5 arguments
输出：
received the following arguments:
sauce
1
2
5
8
