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.framewor k/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,

Perhaps what you want is StringIO. It lets your pretend a string is a
file so ftplib won't choke. You'll have to convert your list to a
string, though (perhaps with join):
from cStringIO import StringIO
fake_file = StringIO("".joi n(my_list))

The StringIO module is your friend, together with a couple of basic
Python techniques.
>>alist = ["<table>\n" , " <tr>\n",
.... " <td>", "Nobody expects the Spanish Inquisition!",
.... "</td>\n", " </tr>\n", "</table>\n"]
>>print ''.join(alist) # but strings don't have a readlines method...
<table>
<tr>
<td>Nobody expects the Spanish Inquisition!</td>
</tr>
</table>
>>> f = StringIO.String IO() f.writelines( alist) f.getvalue( )
'<table>\n <tr>\n <td>Nobody expects the Spanish Inquisition!</td>\n
</tr>\n</table>\n'
>>f.seek(0) # don't forget to reset the file pointer! print f.read() # also has readlines
<table>
<tr>
<td>Nobody expects the Spanish Inquisition!</td>
</tr>
</table>

Introduction
Many websites have a form or a link you can use to download a file. You click a form button or click on a link and after a moment or two a file download dialog box pops-up in your web browser and prompts you for some instructions, such as “open” or “save“. I’m going to show you how to do that using a perl script.
