“collections.OrderedDict”对象没有属性

Question

import pandas as pd

xl=pd.ExcelFile('/Users/denniz/Desktop/WORKINGPAPER/FDIPOLITICS/python.xlsx')

dfs = pd.read_excel(xl,sheet_name=None, dtype={'COUNTRY':str,'YEAR': int, 'govtcon':float, 'trans':float},na_values = "Missing")

dfs.head()

After running the code above i got the following:

collections.OrderedDict object has no attribute 'head'

Answer 1

sheet_name = None will not work and you can combine reading excel file lines like this.

import pandas as pd
import xlrd


dfs=pd.read_excel('/Users/denniz/Desktop/WORKINGPAPER/FDIPOLITICS/python.xlsx',sheet_name=0, dtype={'COUNTRY':str,'YEAR': int, 'govtcon':float, 'trans':float},na_values = "Missing")

dfs.head()

Answer 2

I have read the API reference of pandas.read_excel . pandas.read_excel method will return DataFrame or dict of DataFrames .

As you set sheet_name=None , you will get All sheets returned in the form of a dict of DataFrames . The key of this dict will be the sheet name.

So in your code snippet, dfs is a dict not a DataFrames . Obviously, dict has no head method. Your code should be like this dfs[sheet_name].head() .
