PYTHON：更改列名称

Question

I am reading a excel sheet by using pandas as - pd.read_excel() and then putting it in a list and appending it to the final Data-frame.

The sheet which i am reading have a column name Sales and in the final data-frame i have column with name Item .

AllFields is the Data-frame with all the list of columns.

So my question is while appending the list to the final data-frame the records of the Sales Columns comes under the column name Item .

Example of data which i am reading from sheet

Sales 2013 2014 2015 2016 2017 2018 2019 Units Sold 0 0 0 0 0 0 0 Unit Sale Price $900 $900 $900 $900 $900 $900 $900 Unit Profit $500 $500 $500 $500 $500 $500 $500

and then appending to the data-frame which have columns

Full Project Item Market Project Project Step Round Sponsor Subproduct 2013 2014 2015 2016 2017 2018 2019

reading_book1 = pd.read_excel(file, sheet_name="1-Rollout", skiprows=restvalue).iloc[:10]

EmptyList1 = [reading_book1]

RestDataframe = RestDataframe.append(AllFields).append(EmptyList1)
RestDataframe['Project'] = read_ProjectNumber
RestDataframe['Full Project'] = read_fullProject
RestDataframe['Sponsor'] = read_Sponsor
RestDataframe['Round'] = read_round
RestDataframe['Project Step'] = read_projectstep
RestDataframe['Market'] = "Rest of the World Market"


FinalDataframe = FinalDataframe.append(CADataframe).append(RestDataframe)

You need to use pd.concat

RestDataFrame= pd.concat([AllFields,EmptyList1], axis=1)

And then change the name of Sales column to Item column with

data.rename(columns={'Sales':'Item'}, inplace=True)
