What do you want the file to look like as a result? Do you want brackets on either end and quotes around each item and commas in between? Or do you want each item on a line by itself? Or just what?Karl Knechtel– Karl Knechtel2012-04-11 06:20:56 +00:00Commented Apr 11, 2012 at 6:20

Use writelines() method to write your content.
>>> f = open("test.txt",'w')
>>> mylist = ['a','b','c']
>>> f.writelines(mylist)
file.writelines(sequence)
Write a sequence of strings to the file. The sequence can be any iterable object producing strings, typically a list of strings. There is no return value
Note: writelines() does not add line separators.

w is a list and the write method of the file object doesn't accept list as the error explains.
You can convert w to a string and write that like so:
' '.join(w) #Joins elements with spaces in between
Then you can call:
q.write(str)

If you want to join unicode strings, then you use the join method of a unicode string, so simply:
u' '.join(w). (I assume 2.x since you need to ask this question; in 3.x, strings are normally unicode and you have to go out of your way to create bytes objects.)
Here are two similar posts in Stackoverflow:-
Writing a list to a file with Python
Python: Write a list of tuples to a file
You will get some more options and alternatives there.
