试图将文件名传递给 ExcelWriter

Question

我正在尝试将自定义文件名变量传递给 ExcelWriter，但由于某种原因无法使它的 ExcelWriter 部分工作。如果我在 ExcelWriter 函数中将 "Sheetname" 替换为 "Temp.xlsx" 这有效，但我无法将我的变量传递给该函数。每次脚本为运行.

时，我都需要能够将今天的日期存储在文件名中

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()

在此先感谢您的帮助

Answer 1

当我运行你的程序时，我得到以下错误：

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

您可以通过删除日期部分的正斜杠来修复它：

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()

看起来错误来自打开：

 >>> 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，要么转义这些字符，要么在日期中使用其他字符，如上例所示。
