Convert list to file object without creating an actual file.

[Bart Kastermans]

I have written a little program that takes as input a text file,
converts
it to a list with appropriate html coding (making it into a nice
table).
Finally I want to upload this list as a textfile using ftp.

If homeworkhtml contains the list of lines;
e.g. homeworkhtml = ["<table>", "<tr>", "<td>", "test", "</td>" .....

I want to call:
ftp.storlines("STOR " + filename, homeworkhtml)

which gives me the error
Traceback (most recent call last):
  File "./testhw.py", line 67, in ?
    ftp.storlines("STOR " + filename, homeworkhtml)
  File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/
python2.3/ftplib.py", line 428, in storlines
AttributeError: 'list' object has no attribute 'readline'

Expected since homeworkhtml is in fact not a file.  Is there a way
to convert this list to a file object without first writing it to disc
and
then opening the resulting file?

Best,
Bart
