Write list of list to CSV?

[buran]

After running this from my original file which Im working, It's not writing any data on the CSV, maybe u have encountered/ any idea with this?

I am not sure I understand this

opo = [[ele] for ele in opo] - What we did here is we create a specifically significant variable(ELE) which we put the opo list into the ele list.

we use list comprehension. ele is just a variable that we used to convert the list to list of lists. we don't actually care about it, so we can reuse it in the list coprehension used to turn descname to list of lists
opo = [[ele] for ele in opo]
is same as

new_opo = []
    for ele in opo:
        new_opo.appned([ele])
opo = new_opo[:]

then we put the list into zip and this itertools.izip_longest(*iterables[, fillvalue]) is fill all the blank data a loop until find the longest match/value.

it's same as zip, however if some of the iterables are shorter than others, it will use fillvalue to work as if they were equal length
