Python: Write two lists into two column text file

Question

Say I have two lists: a=[1,2,3] b=[4,5,6] I want to write them into a text file such that I obtain a two column text file:

Answer 1

Simply zip the list, and write them to a csv file with tab as the delimiter:

>>> a=[1,2,3]
>>> b=[4,5,6]
>>> zip(a,b)
[(1, 4), (2, 5), (3, 6)]
>>> import csv
>>> with open('text.csv', 'w') as f:
...    writer = csv.writer(f, delimiter='\t')
...    writer.writerows(zip(a,b))
...
>>> quit()
$ cat text.csv
1       4
2       5
3       6
