I would like to iterate through two lists simultaneously and write each item from both lists, tab-separated on the same line.
word = [\'run\', \'windless\', \'ma
I think you're on the right path. You just need to give the write() function a single line to write.
Like this:
for w, p in zip(word, pron): outfile.write("%s, %s" % (w, p))
