pandas.excelwriter

问题 I am a novice at Python and helping out on a school project. Any help is much appreciated. THANKS. I get an error when it gets to the year 2004 and 2003. And it is caused by the result_list list.

问题 Currently I have a function that writes multiple DataFrames into separate sheets of a new file. However, I am trying to extend the sheets of an existing excel file with data stored in DataFrames. The function that I use: sheet_extensions = [df_1, df_2, df_3, df_4] def save_xls(list_dfs, xls_path): with pd.ExcelWriter(xls_path) as writer: for n, df in enumerate(list_dfs): df.to_excel(writer, 'sheet%s' % n) writer.save() save_xls(list_dfs=sheet_extensions, xls_path='Output.xlsx') I have read

问题 I am attempting to write multiple pandas dataframes which I extracted from a larger dataset into multiple worksheets of an excel workbook. The issue is that it only writes the first dataframe i.e. index[0] , so the resulting workbook has only one worksheet, see sheet1 below. What am I missing? This is a recreation of my problem.

I have tried multiple ways but none of it would work. Perhaps it is because of my poor understanding of Python. Can anyone suggest me how can I wrap text while writing the excel file?

问题 I currently have an excel file with, for minimally viable example, say 3 sheets. I want to change 2 of those sheets to be based on new values coming from 2 pandas dataframes (1 dataframe for each sheet). This is the code I currently have: from openpyxl.writer.excel import ExcelWriter from openpyxl import load_workbook path = r"Libraries\Documents\Current_Standings.xlsx" book = load_workbook('Current_Standings.xlsx') writer = pd.ExcelWriter(path, 'Current_Standings.xlsx', engine='openpyxl')
