This is your problem. You create the textfile list, and then loop over
the list. Now the is are your elements of the list, however you are
passing the list to the open function. That is what the error says, it
expects a string but found a list. The better way to do this would be:
for filename in textlist:
text_file = open(filename, "a")
...

There are a number of ways to to do this and what the best way is might
depend on your text files. If they are very short the easiest way is to
just read the content of your text files and write the content to a
different file. something like this:
for fn in textlist:
fp = open(fn, 'r')
fp.close()
s = fp.read()
s += "I suck at Python and need help")
fp_new = open(fn[:-4]+'_modified.txt','w')
fp_new.write(s)
fp_new.close()
Just for the future this is the numpy list, which is for discussing
issues relating to the numpy python module, the next time you might want
to post a question like this to one of the python beginners lists. This
link might get you started:

[Numpy-discussion] defmatrix 1.3 versus 1.5
Hi I am trying to compile a py2exe app. It works with numpy 1.3 but if I try numpy 1.5 I get an error when loading the app.exe Traceback (most recent call last): File "artisan.pyw", line 109, in File "numpy\__init__.pyo", line 136, in File "numpy\add_newdocs.pyo", line 9, in File "numpy\lib\__init__.pyo", line 5, in File "numpy\lib\index_tricks.pyo", line 15, in ImportError: No module named defmatrix I've noticed that there is a change in the location of defmatrix from 1.3 to the newer 1.5. 1.3 numpy/core/defmatrix 1.5 numpy/matrixlib/defmatrix How could I make py2exe work? Any tips? Thanks ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion

[Numpy-discussion] Getting a clone copy of the NumPy repository.
Hello everyone, I am a newbie on this open source world, and sincerely trying to make contribution to the development of Numpy. I was trying to learn about making patches from http://docs.scipy.org/doc/numpy/dev/gitwash/patching.html but unable to get the clone of Numpy repository. In the terminal error massage shown is - $hector@hector:~$ sudo git clone git://github.com/numpy/numpy.git [sudo] password for hector: Initialized empty Git repository in /home/hector/numpy/.git/ github.com[0: 207.97.227.239]: errno=Connection timed out fatal: unable to connect a socket (Connection timed out) $hector@hector:~$ My internet is quite good at the moment but unable to understand why am I getting this error. Any help regarding this will be extremely helpful and encouraging for me.

[Numpy-discussion] float conversion
hi every1, I got the following issue: I wrote a function that converts binary strings into a decimal value (binary expansion). When I write type(x) to find out the type of the value I get NoneType. Therefore I can't convert it into anything else, such as float numbers, since command float(x) returns TypeError: float() argument must be a string or a number Any ideas what to do with this (e.g. convert to floating numbers)? cheers, Alex ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
