使用Enthought Canopy從命令行參數運行.py代碼

Question

我准備了一個從Excel文件讀取的Python腳本：

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)

如果我通過Jupyter Notebook執行，它將成功執行。

但是當我通過傳遞以下參數從命令行運行它時，出現了錯誤

命令行：

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

錯誤信息：

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

您文件的名稱也是一個參數。

意思是，
sys.argv[0]被分配為MergeFilesv1_2.py ，
sys.argv[1]分配為"C:\\Desktop\\MasterFile.xlsx" ，依此類推。
