ERROR
[Wed Jun 08 20:29:51 2011] [error] [client 192.168.1.9] Traceback
(most recent call last):
What is all this extraneous date/error/ip address nonsense in the
traceback? Where does it come from?
TypeError:
cannot concatenate 'str' and 'NoneType' objects
I am extracting form field name / value from an html, but then it
gives the above error and does
not display the value of the variable 'name' entered in the respective form.
What is the value of the variable 'name'?
Hint: read the error message that you get when you try to concatenate a
string with the None object:
>>> "spam" + None
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
