AttributeError: 'collections.OrderedDict' object has no attribute 'value_counts'

Question

我收到一条错误消息，似乎无法弄清楚。当我尝试计算从第 4 行开始的 ws1 F 列中出现值 0 的实例数，然后将其写到 ws3 M 列第 2 行时，就会发生这种情况。以前有人遇到过这个错误吗？

Answer 1

当您使用 sheet_name=None 时，您将得到一个 dict 对象，而不是 Series 或 DataFrame 对象。

并且 dict 对象没有方法 .value_counts()。

在你的情况下，你可以这样做：

 series = pd.read_excel(input_file, sheetname='ur_sheet_name', skiprows = [5], usecols = "F", squeeze = True)

或者：

series = pd.read_excel(input_file,skiprows = [5], squeeze = True)['title_of_column_F']
