如何在 Python 中的 Microsoft Excel 中打开 csv 文件？

Question

base_path = os.path.dirname(os.path.abspath(__file__))          
_csvFilename = os.path.join(base_path, "bcForecasting.csv")
_csvFile = open (_csvFilename, 'wb')
_csvFile = csv.writer(_csvFile, quoting=csv.QUOTE_ALL)

_Header = self.makeIntoList (self.root.tss.series () [0].getAllTimes (), self.originalTimesteps + _futurePeriods)
_csvFile.writerow (_Header)

Now I want to open the created bcForecasting.csv file in Excel. How to do it in Python?

Answer 1

Usually on Windows the .csv filetype is configured to be opened by Excel. In this case you can just do:

from subprocess import Popen
p = Popen('filename.csv', shell=True)

In case it does not work, try pointing the full path of the Excel application:

subprocess.Popen(r'C:\Program Files (x86)\Microsoft Office\Office14\EXCEL.EXE stack.csv')

Answer 2

You can use the 'startfile' command from the os library.

import os
os.startfile('filename.csv')

Do make sure to specify the path of the file or to set the working directory to the path where the file is located.

Answer 3

On a mac, use the following:

import os
os.system('open filename.csv')

Make sure to specify the path of the file or to set the working directory to the path where the file is located.
