我使用熊猫以以下方式写入excel文件:
import pandas writer = pandas.ExcelWriter('Masterfile.xlsx') data_filtered.to_excel(writer, "Main", cols=['Diff1', 'Diff2']) writer.save()
Masterfile.xlsx已经包含许多不同的选项卡。但是,它尚未包含“ Main”。
熊猫正确地写入“主”表,不幸的是,它也删除了所有其他标签。
Pandas文档说,它对xlsx文件使用openpyxl。快速浏览一下其中的代码ExcelWriter可以提示可能会发生以下情况:
import pandas from openpyxl import load_workbook book = load_workbook('Masterfile.xlsx') writer = pandas.ExcelWriter('Masterfile.xlsx', engine='openpyxl') writer.book = book ## ExcelWriter for some reason uses writer.sheets to access the sheet. ## If you leave it empty it will not know that sheet Main is already there ## and will create a new sheet. writer.sheets = dict((ws.title, ws) for ws in book.worksheets) data_filtered.to_excel(writer, "Main", cols=['Diff1', 'Diff2']) writer.save()
