I would rewrite your code as follows:

import glob
from itertools import izip

def extract_meaningful_info(line):
    return line.rstrip('\n').split('[')[0]

MA_files = glob.glob("MA*continuous*2")

with open("MA_continuous_results.csv", "wb") as outfile:
    outfile.write("\t".join(MA_files) + '\n')
    for fields in izip(*(open(f) for f in MA_files)):
        fields = [extract_meaningful_info(f) for f in fields]
        outfile.write('\t'.join(fields) + '\n')

(code is for python2)
