It's behaving the same. You're overlooking the fact that the empty string is
False:
In [1]: bool('')
Out[1]: False
Length zero sequences are normally False, but you can override this in a
subclass by implementing the __nonzero__ method:
In [2]: class mystr(str):
...: def __nonzero__(self):
...: return True
In [3]: bool(mystr(''))
Out[3]: True

That's not the standard format for a traceback in Python and you don't
provide enough context like:
- your python version
- the framework that produces the non-standard traceback
- a significant portion of your code
That makes it harder than necessary to find out what's going on.
Python 2.4.6 (#2, Jan 21 2010, 23:45:25)
[GCC 4.4.1] on linux2
Type help, copyright, credits or license for more information.
@ in None
Traceback (most recent call last):
File stdin, line 1, in ?
TypeError: iterable argument required
So mail = None means exactly that, you somehow assigned None to the mail
variable.
Note that newer Python versions give a slightly improved error message:
$ python2.5 -c '@ in None'
Traceback (most recent call last):
File string, line 1, in module
TypeError: argument of type 'NoneType' is not iterable
Background: the 'in' operator tries hard to produce a meaningful result
before it gives up:
class A:

... print name
... raise AttributeError
...

__contains__
__iter__

My wild guess is that the trouble is in `if @ in mail` . You can only
test somthing `in` something if the second thing is iterable. So when
you don't supply a value via `?mail=' -- maybe the code that sets the
value of `mail` from the URL (code you don't show us) sets `mail=None`,
your server-side code blows up. Things would be simpler if you included
a traceback in your error logging.

I think you and Peter are right. Somehow mail variable which is taken
its value from a form field is assigned a None value.
Here is the hosting.html part of the code that include the form
variable mail
form method=post action=
input type=text name=mail value=Ποιό είναι το email σου?br
textarea name=comment cols=40 rows=5
Σχολιάστε ή ρωτήστε με σχετικά
/textareabr
input type=hidden name=page value=hosting.html
input type=submit value=Ρώτα
/form
But as you can see it has a default value of Ποιό είναι το email
σου?
So how can be of a NoneType ?
Things would be simpler if you included a traceback in your error logging.
You mean the web server's last error log messages for the error.log
file?
