TypeError: unsubscriptable object

[k.retheesh@gmail.com]

Can anybody tell me why am I getting this error message while trying to
print a part of a string. Is there a better approach for this...

Traceback (most recent call last):

TypeError: unsubscriptable object

It means either 'Function' or 'Description' is not a sequence.
Try inserting print statements to see what values they are.

e.g:

a = 2
a[:10]

will give me an 'unsubscriptabl e object'

You should do this:

print type(Function), type(Descriptio n)
raise SystemExit

Instead of this:

print template % (ID, IID, Function[:10], Description[:10],ErrorNumber, StatusCD)

Then probably you will see:

<type 'int'> <type 'int'>

instead of

<type 'str'> <type 'str'>


or something similar. (Of course in your case, it can be 'float instead of list' or 'dictionary instead of tuple' etc.)

Then you should debug your program and find out why the 'Function' and 'Description' objects are not string but int.

Re: TypeError: unsubscriptable object

I did the same,

The function type is < NoneType> and the description type is <Unicode>
so how can i print a part of this 2 output.

These values are returned by database.

Thanks

The unicode object IS subscriptable. It is a unicode string which has
characters.
The value None is not subscriptable. It probably means that you have a
NULL value in your database.
Try the following:

def nulltoemptystr( value):
if value is None:
return "<EMPTY>"
else:
return value[:10]

print template % (ID, IID, nulltoemptystr( Function), nulltoemptystr( Description),Er rorNumber, StatusCD)


You can also try to do the same in SQL. For example, this works with
FireBird, PostgreSQL and many others:

select coalesce(Functi on,"") as Function from TableName

instead of

select Function from TableName

But first of all, I would recommend you to go over the Python tutorial.
It explains these things and more.

Best,

Because you don't use a string? The error message is pretty clear:

TypeError: unsubscriptable object

So - what are Function[:10], Description[:10] ? You _assume_ they are
strings, seems not to be the case.
