Question

我准备了一个从Excel文件中读取的Python脚本：

import glob
import pandas as pd
import StringIO
import sys
import os
from xlrd import open_workbook

filelocation = str(sys.argv[0])
outputlocation = str(sys.argv[1])
FileExtension = str(sys.argv[2])
Separator = str(sys.argv[3])



#filelocation = 'C:\Desktop\MasterFile.xlsx'
#outputlocation = 'C:\Desktop\output'
wb = open_workbook(filelocation)

如果我通过Jupyter Notebook执行它，它会成功执行。

但是当我通过传递以下参数从命令行运行它时，它会给我一个错误

命令行：

python MergeFilesv1_2.py "C:\Desktop\MasterFile.xlsx" "C:\Desktop\output" ".csv" ","

错误消息：

Traceback (most recent call last):
File "MergeFilesv1_2.py",line 22, in <module>
wb = open_workbook(filelocation)
File "C:\Users\Sha\appData\Local\Enthought\Canopy\User\lib\site-packages\xlrd\_init__.py",line 441, in open_workbook

Answer 1

您的文件名也是一个参数。

这意味着，
sys.argv[0]被指定为MergeFilesv1_2.py，
sys.argv[1]被指定为"C:\Desktop\MasterFile.xlsx"，依此类推。

使用Enthought Canopy从命令行参数运行.py代码
