Python 编辑多个工作表

Question

我想编辑存在于同一 Excel 文件中的多个工作表，然后将它们与所做的调整一起保存。这些工作表具有相同的列 headers，分别称为“贷方”和“借方”。我创建的代码如下：

import pandas as pd
import numpy as np

class blah:
    def __init__(self, path, file_in, file_out):
        self.path = path
        self.file_inviato = file_in
        self.file_out = file_out
        
    def process_file(self):
        df = pd.read_excel(self.path + self.file_in, sheet_name=None, skiprows=4)
       
        
       ****Here is where I am struggling in amending both worksheets at the same time****
       
       #  df = df.columns.str.strip()
       #  df['Col1'] = np.where((df['Col2'] == 'KO') | (df['Col2'] == 'OK'), 0, df['Col1'])
        



        writer = pd.ExcelWriter(self.path + self.file_out, engine='xlsxwriter')
        
        for sheet_name in df.keys():
            df[sheet_name].to_excel(writer, sheet_name=sheet_name, index=False)
            
        writer.save()

    
b = blah('path....',
         'file in....xlsx',
         'file out.xlsx')


b.process_file()

Answer 1

找到解决方法：

for sheet_name in df.keys():
            df[sheet_name] = df[sheet_name].rename(columns=lambda x: x.strip())


            df[sheet_name]['Col1'] = np.where((df[sheet_name]['Col2'] == 'KO') | 
                                               (df[sheet_name]['Col2'] == 'OK'), 0, df[sheet_name]['Col1'])
