Writing and modifying an existing workbook using P

问题:

I am new to Python and working on a project that I could use some help on. So I am trying to modify an existing excel workbook in order to compare stock data. Luckily, there was a program online that retrieved all the data I need and I have successful been able to pull the data and write the data into a new excel file. However, the goal is to pull the data and put it into an existing excel file. Furthermore, I need to overwrite the cell values in the existing file. I believe xlwings is able to do this and I think my code is on the right track, but I ran into an unexpected error. The error I get is:

com_error: (-2147023174, 'The RPC server is unavailable.', None, None)  

I was wondering if anyone knew why this error came up? Also, does anyone know how to fix it? Is it fixable? Is my code wrong? Any help or guidance is appreciated. Thank you.

import good_morning as gm
import pandas as pd
import xlwings as xw

#import income statement, balance sheet, and cash flow of AAPL
fd = gm.FinancialsDownloader()
fd_frames = fd.download('AAPL')

#Creates a DataFrame for only the balance sheet
df1 = pd.DataFrame(list(fd_frames.values())[0])

#connects to workbook I want to modify
wb = xw.Book  (r'C:/Users/vince/OneDrive/Documents/Python/Project/spreadsheet.xlsm')

#sheet I would like to modify
sht = wb.sheets[1]

#modifies & overwrites values in my spreadsheet (this is where I get the commerror)
sht.range('M6').value = df1

Your issue is the OneDrive referenced in your directory is not reachable by the program. This can be caused by many things. Improper credentials, OneDrive is off, or simpler the OneDrive does not allow access from a program rather then a user. Try downloading the file you wish to read and write and save it to a directory stored on your computer and point the program to the new directory and see what happens then.

The error message tuple you get indicates that the RPC server you try to connect to is not available. This failure can happen if the RPC server is offline or if your program cannot connect to the network in which the RPC server resides.

The RPC server is unavailable.

RPC stands for Remote Procedure Call. A RPC server is usually another computer residing somewhere else in your network or a network you are connected to. Via the RPC interface you can send function requests with parameters to the server and the server will execute these requests for you and return the apropriate answer. It mimics regular function calls on your machine with the difference that these function calls are executed on the remote RPC server.

From what you wrote in your explanation of the problem I assume you did not mean to contact a remote server at all to do the necessary task. I would suggest removing or replacing code which tries to connect to a remote service by code which works locally on your machine.

This line points onto a directory structure which refers to a directory called OneDrive. Is this a remote directory? Try to place your spreadsheat somewhere else in a folder you are shure is accessible by the user who runs your program and is not a remote directory.

#connects to workbook I want to modify
wb = xw.Book  (r'C:/Users/vince/OneDrive/Documents/Python/Project/spreadsheet.xlsm')

The following lines also imply a connection to the internet, just by word meaning. I am not familiar with the library you are using, so this could also be just some weird nameing of functions. All I am saying here is, that I am not shure.

#import income statement, balance sheet, and cash flow of AAPL
fd = gm.FinancialsDownloader()
fd_frames = fd.download('AAPL')
