如何將excel中的某個sheet保存成csv文件

直接上代碼：

import xlrd  
#import csv  
#import xlwt
import pandas as pd 
def csv_from_excel(excel_file):  
    workbook = xlrd.open_workbook(excel_file)  
    all_worksheets = workbook.sheet_names()  
    for worksheet_name in all_worksheets: 
    	#data_xls = pd.read_excel(excel_file, worksheet_name, skiprows=[0], index_col=None)
    	if '_Details' in worksheet_name:
    		data_xls = pd.read_excel(excel_file, worksheet_name, index_col=None)
    		data_xls.to_csv(r'D:/csv/'+ worksheet_name + '.csv', encoding='utf-8') 
        #worksheet = workbook.sheet_by_name(worksheet_name)  
        #your_csv_file = open(''.join([worksheet_name,'.csv']), 'wb')  
        #wr = csv.writer(your_csv_file, quoting=csv.QUOTE_ALL)  
  
  
        #for rownum in xrange(worksheet.nrows):  
        #    wr.writerow([unicode(entry).encode("utf-8") for entry in worksheet.row_values(rownum)])  
        #your_csv_file.close()
