Question

我正在尝试将自定义的文件名变量传递给ExcelWriter，但由于某些原因无法使ExcelWriter部分工作。如果我在ExcelWriter函数中将“Sheetname”替换为“Temp.xlsx”，则此方法有效，但我无法将变量传递给函数。每次运行脚本时，我都需要能够在文件名中存储今天的日期。

Spreadsheet = pandas.DataFrame()
Sheetname = 'Makino Machine Metrics ' + time.strftime("%m/%d/%Y") +'.xlsx'
writer = pandas.ExcelWriter(Sheetname, engine = 'xlsxwriter')
Spreadsheet.to_excel(writer, sheet_name= 'Results',index = False)
workbook = writer.book
worksheet = writer.sheets['Results']
writer.save()

先谢谢你的帮助

当我运行你的程序时，我收到以下错误：

IOError: [Errno 2] No such file or directory: 
         'Makino Machine Metrics 07/12/2016.xlsx'

您可以通过从日期部分删除正斜杠来修复它：

import pandas
import time

Spreadsheet = pandas.DataFrame()
Sheetname = 'Makino Machine Metrics ' + time.strftime("%m_%d_%Y") +'.xlsx'
writer = pandas.ExcelWriter(Sheetname, engine = 'xlsxwriter')

Spreadsheet.to_excel(writer, sheet_name='Results', index=False)
workbook = writer.book
worksheet = writer.sheets['Results']
writer.save()

看起来错误来自于开放：

 >>> open('12/12/12.xlsx', 'w')   
 Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 IOError: [Errno 2] No such file or directory: '12/12/12.xlsx'

因此，要么逃避这些字符，要么在日期中使用其他字符，如上例所示。
