运行 来自命令行参数的 .py 代码，使用 Enthought Canopy

Question

我准备了一个 Python 脚本，它从 Excel 个文件中读取：

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，它执行成功。

但是当我通过传递以下参数从命令行 运行 它时，它给我一个错误

命令行：

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

错误信息：

Traceback (most recent call last):

Answer 1

您的文件名也是一个参数。

也就是说，
sys.argv[0] 分配为 MergeFilesv1_2.py、
sys.argv[1] 被分配为 "C:\Desktop\MasterFile.xlsx" 等等。
