Hi All,
I am trying to do a really simple file operation, yet, it befuddles me...
I have a few hundred .csv files, and to each file, I want to manipulate the
data, then save back to the original file. The code below will open up the
files, and do the proper manipulations-- but I can't seem to save the files
after the manipulation..
How can I save the files-- or do I need to try something else maybe with split,
join, etc..
import os
import csv
for filename in os.listdir("/home/matthew/Desktop/pero.ngs/blast"):
with open(filename, 'rw') as f:
reader = csv.reader(f)
for row in reader:
print ">",row[0],row[4],"\n",row[1], "\n", ">", row[2],
"\n", row[3]
Thanks in advance, Matt
