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 -- http://mail.python.org/mailman/listinfo/python-list
