Read the lines from the old file and replace '\t' with ',' in the new file. This should do:

with open('oldfile.txt') as fin, open('newfile.txt', 'w') as fout:
    for line in fin:
        fout.write(line.replace('\t', ','))

Use the str.replace() method like this:

>>> s = '2\t2*6\t12'
>>> print s
2       2*6     12
>>> s.replace('\t', ',')
2,2*6,12
