在不覆盖 Excel 文件的情况下写入工作表的最佳方法是什么？

Question

我有一个名为 MasterFile 的 Excel 文件。在 MasterFile 中，我有多个带有公式的工作表。我想使用下面的代码更新 MasterFile 中的一张表，而不会覆盖我的任何数据或公式。

到目前为止，这是我的代码：

from bs4 import BeautifulSoup
import requests
import pandas as pd
from openpyxl import load_workbook

url = 'http://www.baseballpress.com/lineups'

soup = BeautifulSoup(requests.get(url).text, 'html.parser')

players = [i.text for i in soup.find_all('a', {'class': 'player-link'})]


my_dict = (players)

df = pd.DataFrame(pd.Series(my_dict))

writer = pd.ExcelWriter('my2nd_webscrape.xlsx')
df.to_excel(writer,'Sheet1')
writer.save()

我在How to write to an existing excel file without breaking formulas with openpyxl? 中找到了有关此主题的一些信息，但我不确定如何调整我的代码。

试试这个：

from bs4 import BeautifulSoup
import requests
import pandas as pd
from openpyxl import load_workbook

book = load_workbook('my2nd_webscrape.xlsx')
writer = pd.ExcelWriter('my2nd_webscrape.xlsx')
writer.book = book

url = 'http://www.baseballpress.com/lineups'
soup = BeautifulSoup(requests.get(url).text, 'html.parser')
players = [i.text for i in soup.find_all('a', {'class': 'player-link'})]
my_dict = (players)

df = pd.DataFrame(pd.Series(my_dict))
df.to_excel(writer,'Sheet1')
writer.save()
writer.close()
