Write list of list to CSV?

[buran]

the only problem I see is that dlist is already list of lists. But this will not prevent writing to file (although it may be not what you want:

Output:
device1,HundredGigE0/2/0/0,"['ALPHANUMERICWITHCHARAC;;;', 'ALPHANUMERICWITHCHARAC;;;', 'ALPHANUMERICWITHCHARAC;;;']"
,HundredGigE0/2/0/0.242,
,HundredGigE0/2/0/0.244 l2transport,
,HundredGigE0/2/0/1,
,HundredGigE0/2/0/0.244,
device1,TenGigabitEthernet1/1/0.138,['ALPHANUMERICWITHCHARAC;;;']
device1,TenGigE0/1/0/15,['ALPHANUMERICWITHCHARAC;;;']

note that lst column is str repr of a list.
If you make it like this

import itertools
import csv
opo = ['device1', 'device1', 'device1']
intfname = [['HundredGigE0/2/0/0', 'HundredGigE0/2/0/0.242', 'HundredGigE0/2/0/0.244 l2transport', 'HundredGigE0/2/0/1', 'HundredGigE0/2/0/0.244'], ['TenGigabitEthernet1/1/0.138'], ['TenGigE0/1/0/15']]
descname = [['ALPHANUMERICWITHCHARAC;;;', 'ALPHANUMERICWITHCHARAC;;;', 'ALPHANUMERICWITHCHARAC;;;'], ['ALPHANUMERICWITHCHARAC;;;'], ['ALPHANUMERICWITHCHARAC;;;']]# ['0/2/0/0info1', '0/2/0/0.242info2', '0/2/0/0.244info3']

opo = [[ele] for ele in opo]
 
## EXPORT AS CSV
with open('intlist.csv', 'w', newline='') as updatecsv:
    write = csv.writer(updatecsv, delimiter=',',lineterminator='\n')
    for cols in zip(opo,intfname,descname):
        rows = itertools.zip_longest(*cols, fillvalue='')
        write.writerows(rows)
updatecsv.close()
print ("Done...")

the output will be

Output:
device1,HundredGigE0/2/0/0,ALPHANUMERICWITHCHARAC;;;
,HundredGigE0/2/0/0.242,ALPHANUMERICWITHCHARAC;;;
,HundredGigE0/2/0/0.244 l2transport,ALPHANUMERICWITHCHARAC;;;
,HundredGigE0/2/0/1,
,HundredGigE0/2/0/0.244,
device1,TenGigabitEthernet1/1/0.138,ALPHANUMERICWITHCHARAC;;;
device1,TenGigE0/1/0/15,ALPHANUMERICWITHCHARAC;;;

Note that desc values go to first three lines, I don't know if this is correct

What I try to say is if the print output is OK, then second part should work too (i.e. the lists are populated with values, not empty)

you can make opo list of lists by design, when you create it in the first place.

Hi, yes I have removed the list of list convertion for dlist a while ago.

Yes, a little bit odd. though will try to search for solution. Not sure if there a proplem with my ubuntu server since the data was pullout from there.

But I have checked the permission etc from ubuntu and seem like its working.

But you said that the print lines work fine (i.e. you get the lists you want)
Also you say that you can write if separate the second part (i.e. no problem with permissions to write)

@buran, its now working... hooooo :) problem is with the current location of my directory wherein the script pullout/move to different directory.. so I have to put the absolute path when saving on CSV.

Thanks for your help man.
