RuntimeError:dictionary keys changed during iteration

引用\[1\]中的代码存在错误，因为在遍历字典的同时删除字典元素会导致RuntimeError: dictionary changed size during iteration错误。为了解决这个问题，可以使用引用\[2\]中的代码进行改正。改正后的代码将字典的键转换为列表后再进行遍历和删除操作。这样就可以避免在遍历过程中修改字典的大小，从而避免了RuntimeError错误的发生。引用\[3\]中提到了根据PEP-0234的规定，字典在遍历时不能进行修改，所以需要先将键转换为列表或集合保存后再进行删除操作。这是一种解决方案。
