Question

I need to write

ranks[a], ranks[b], count

to a file, each time on a new line

I am using:

file = open("matrix.txt", "w")
for (a, b), count in counts.iteritems():
    file.write(ranks[a], ranks[b], count)

file.close()

but this is not working and returns

TypeError: function takes exactly 1 argument (3 given)

Answer 1

As the error says, file.write only takes one arg. Try:

file.write("%s %s %s" % (ranks[a], ranks[b], count))
