Issue writing CSV using CSV module in python

Question

Trying to print some strings as rows into a csv however, it gets printed as a column . Code is:

with open('test.csv','w') as b:
a = csv.writer(b)
a.writerows(strings)
b.close()

Output is

GGKKKTKICDKVSHEEDRISQ   ISEILFHLSTKDSVRTSALST   FDSHRDSWIRKLRLDLGYHHD   HLDVHCFHDNKIPLSIYTCTT

I would need it as rows like:

GGKKKTKICDKVSHEEDRISQ

ISEILFHLSTKDSVRTSALST

Answer 1

writerows expects a list of lists - each inner list a row. I assume that strings is a list of strings, and thus treated like a single row. To covert it to a list of rows, which is what you want, use:

a.writerows([[x] for x in strings])
