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列F中出现值0的实例数，然后将其写到ws3列M行2中时，会发生这种情况。

Error
    counts = series.value_counts()

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

import openpyxl as xl 
import os
import pandas as pd 
  
input_dir = 'C:\\work\\comparison\\NNM'

newFile = 'Comparison.xlsx'

         if os.path.isfile(file) and file.endswith(".xlsx")]

使用sheet_name=None时，会得到dict对象，而不是Series或DataFrame对象。

并且dict对象没有方法.value_counts()。

在您的情况下，您可以这样做：

 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']

AttributeError：“ collections.OrderedDict”对象没有属性“ value_counts”
