如何使用Python编写Excel文件，并在意图的每一行中添加意图，后跟相同的字符串？

问题描述

嗨，我有上面的代码编写一个excel文件：

def write_excel(df):
    writer = pd.ExcelWriter("PATH\output.xlsx",engine = 'xlsxwriter')  

    workbook=writer.book
    worksheet=workbook.add_worksheet('sheet')
    writer.sheets['sheet'] = worksheet

    df.to_excel(writer,sheet_name='sheet',startcol = 0,startrow = 0)
    writer.save()

write_excel(df)

df是一个看起来像这样的数据框：

ID             NUMBER      OBJECT
1345471886     SIZE-43     GHJ
1481654311     SIZE-48     IJF  
8620787660     SIZE-67     EFH

并且我在下面添加了此代码，以在OBJECT列中添加一个缩进和字符串“ hello you，hello”：

def add_agg_columns(df):
    df["OBJECT"] = df["OBJECT"] + "\n\nhello you,hello\n" 
    
    return df

我得到：

ID             NUMBER      OBJECT
1345471886     SIZE-43     GHJ\n\nhello you,hello\n
1481654311     SIZE-48     IJF\n\nhello you,hello\n  
8620787660     SIZE-67     EFH\n\nhello you,hello\n

在我的excel文件中，我希望最终输出看起来像：

ID             NUMBER      OBJECT
1345471886     SIZE-43     GHJ

                           hello you,hello
1481654311     SIZE-48     IJF
                        
                           hello you,hello
8620787660     SIZE-67     EFH

                           hello you,hello

但是我现在写excel文件时得到的只是：

ID             NUMBER      OBJECT
1345471886     SIZE-43     GHJ
1481654311     SIZE-48     IJF  
8620787660     SIZE-67     EFH

解决方法

下面的代码实际上已将其修复！

last_sentence = """ 
hello you,hello
"""

def add_agg_columns(df):
    df["OBJECT"] = df["OBJECT"] + last_sentence 
    
    return df

def write_excel(df):
    writer = pd.ExcelWriter("PATH\output.xlsx",engine = 'xlsxwriter')  

    workbook=writer.book
    worksheet=workbook.add_worksheet('sheet')
    writer.sheets['sheet'] = worksheet

    df.to_excel(writer,sheet_name='sheet',startcol = 0,startrow = 0)
    writer.save()

write_excel(df)
