beginner level Python:- output XLS spreadsheet instead of using tabulate
#1
I have a python script that uses the 'print tabulate' to output the data in CLI.
I would like an easy way output to XLS workbook using 'xlwt' instead.

This is the working python script that outputs to 'print tabulate'
#!/usr/bin/env python

Thanks for posting your solution. I recommend you to alter the part of code you use to open and write to file. See here how context managers (with) are usually used with files.

Now I would like to output to XLS workbook using 'xlwt' instead.
I would also like to keep the original headers
["MACADDRESS", "IPADDRESS", "INTERFACE","ENCAP", "TENANT", "APP PROFILE", "EPG"]

import xlwt
	wb = xlwt.Workbook()
	ws = wb.add_sheet('EndPoints')

	ws.write(--==Just working on this bit==--)

	wb.save('ACI-Endpoints.xls')

is this better?

    # Write downloaded data to ACI-Endpoints.csv
    myFile = open('ACI-Endpoints.csv', 'w')
    with myFile as f:
    	writer = csv.writer(myFile)
    	writer.writerows(data)
    	f.closed

If the Excel file doesn't need special formatting, you can write a csv and convert to xls by running an external command from python, for example if you have libreoffice installed on your computer, the following should work:
returncode = subprocess.call("soffice --headless --convert-to xls ACI-Endpoints.csv")
if returncode:
    raise RuntimeError(('Conversion to xls failed for', 'ACI-Endpoints.csv'))
You can also convert to xlsx with soffice --headless --convert-to xlsx:"Calc MS Excel 2007 XML" file.csv

If using Pandas and also Jupyter Notebook the format look better,
The DataFrame and Excel look alike,and Pandas has df.to_excel('ip.xlsx')is all that's needed to save to Excel.
tabulate to also work with Pandas DataFrame.
Here a image with test a did,Anaconda can help if want to try this(without all the installing) my tutorial.
