Pandas 具有动态标题的数据框

Pandas dataframe with dynamic title

假设我有以下 dataframe:

df = pd.DataFrame({
        'A':list('abcdef'),
         'B':[4,5,4,5,5,4],
         'C':[7,8,9,4,2,3],
         'D':[1,3,5,7,1,0],
         'E':[5,3,6,9,2,4],
         'F':list('aaabbb')
})

我想给它一个用户提供的标题,例如: title = 'The sales'

如何将 title 添加到 df,以便在发送到 Excel sheetpdf 时显示为: `

{title} in this case *The sales*
 A  B  C  D  E  F
0  a  4  7  1  5  a
1  b  5  8  3  3  a
2  c  4  9  5  6  a
3  d  5  4  7  9  b
4  e  5  2  1  2  b
5  f  4  3  0  4  b

搜索可能的解决方案导致添加 column title,而我想要的是添加 dataframe 标题。

您可以使用 xlwings,它是使用 python

将数据导入 excel 的最佳库之一
import pandas as pd
import xlwings as xw

df = pd.DataFrame({
        'A':list('abcdef'),
         'B':[4,5,4,5,5,4],
         'C':[7,8,9,4,2,3],
         'D':[1,3,5,7,1,0],
         'E':[5,3,6,9,2,4],
         'F':list('aaabbb')
})


title = 'The sales'

wb = xw.Book("sales.xlsx")

sheet = wb.sheets['Sheet1']

sheet.range('A1').value = title

sheet.range('A2').options(pd.DataFrame, index=False).value = df

wb.save('sales.xlsx')
wb.close()

#如果你不需要Index就保持在上面 #如果需要Index put index=True

这是使用 xlsxwriter 作为 Pandas Excel 引擎的一种方法。使用 openpyxl 也可以进行类似的操作:

import pandas as pd

df = pd.DataFrame({'A': list('abcdef'),
                   'B': [4, 5, 4, 5, 5, 4],
                   'C': [7, 8, 9, 4, 2, 3],
                   'D': [1, 3, 5, 7, 1, 0],
                   'E': [5, 3, 6, 9, 2, 4],
                   'F': list('aaabbb')})

writer = pd.ExcelWriter('test.xlsx', engine='xlsxwriter')

# Shift the dataframe down one row in the Excel file.
df.to_excel(writer, sheet_name='Sheet1', startrow=1)

# Get the xlsxwriter workbook and worksheet objects.
workbook  = writer.book
worksheet = writer.sheets['Sheet1']

# Write the title to the worksheet.
title = 'The sales'
worksheet.write(0, 0, title)

writer.save()

输出:
