[我正在尝试构建一个可以选择数字或对象dtype的函数，并将NaN值替换为与dtype相关的值，例如，数字为0，对象为'Missing Value'。
我的代码和错误是：
test_df.select_dtypes(include=[float,int]).apply(test_df.fillna(0, inplace=True))
TypeError ：（“'NoneType'对象不可调用”，'在索引字数处发生']
test_df.select_dtypes(include=[object]).apply(test_df.fillna('Missing Value', inplace=True))
TypeError ：（“'NoneType'对象不可调用”，“在索引地址处发生”）
我不确定如何解决这些错误。同样，如果有人认为我正在以错误的方式高兴地看到另一个解决方案。我需要大量执行此操作，并寻找完成工作的最有效方法。
我已经阅读了一些类似的文章，但问题似乎非常针对特定人员的问题和代码。
感谢您的任何帮助。
