python output data type confusion

Hi all this is the code I am trying to run. I am not a computer scientist and I know this is an easy answer I just do not have the tools to answer it. I am trying to get this list printed to a text file. It works if I print to screen. The error I get is this: "TypeError: expected a character buffer object"

here is the code

input = open('Tyger.txt', 'r')
text = input.read()
wordlist = text.split()

output_file = open ('FrequencyList.txt','w')
wordfreq = [wordlist.count(p) for p in wordlist]

#Pair words with corresponding frequency

dictionary = dict(zip(wordlist,wordfreq))

#Sort by inverse Frequency and print

aux = [(dictionary[key], key) for key in dictionary]
aux.sort()
aux.reverse()

for a in aux: output_file.write(a)

Thanks!

you can write your code like: 

input = open('tyger.txt','r').read().split()
......
.........
............
for a in aux:
    output_file.write(str(a))
    output_file.close()

you must close() a file what you have opened to write,otherwise you won't be able to use the file.

As I said in the comments above, change output_file.write(a) to output_file.write(str(a)). When you print something, Python attempts to do an implicit string conversion of whatever you are printing. That is why printing a tuple (as you are doing here) works. file.write() does no implicit conversion, so you have to covert it yourself with str().

As noted in the comments to this answer, you probably need to call .close() on the file.
