help with str()

[Tuxtrax]

Hi all.

I have need of assistance on something that should be very simple, and
is driving me absolutely batty. This is a code snippet from a short
program that downloads news headers via nntplib. getinput() is simply a
function I have defined for using raw_input in a friendly fashion.
message_request = getinput("\nHow many posts should I be interested in?
[max 10,000]")

if int(message_req uest) > int(number_of_m essages):
print "\nRequest exceeds current available message count.
Adjusting to %s posts" % number_of_messa ges
message_request = number_of_messa ges
elif int(message_req uest) > 10000:
print "\nRequest exceeds program capacity. Assuming max of 10,000
posts, and continuing ...."
message_request = "10000"
The trouble comes in when I try to convert last_message into a string:

last_message = str(int(first_a vailable_messag e) +
int(message_req uest))

I also tried variations on a theme like:

last_message = int(first_avail able_message) + int(message_req uest)
string_result = str(last message)

No dice. In every case, I get the following error:

Traceback (most recent call last):
File "headhunter.py" , line 317, in ?
response, poster = n.xhdr("from",
first_available _message+"-"+str(last_mess age))
TypeError: 'str' object is not callable

I have tried everything I could think of and there is only one
possibility still left that I can think of. My theory is this: by using
the int() function, I am typing the numbers in the last_message
assignment to type integer, and str() is expecting type float, or
something.

I am stuck. Thanks for any help you all can provide. I appreciate it.

best regards,

Mathew

Maybe this rings a bell:

str(5) '5' str = "don't do this"

str() will work on ints. str() will even work on classes if you have
the right special method handler defined.

You might want to verify that displaying the value of "str" gives you
something like <built-in fucntion str>. You can do this by using "print
str". Might be fun to try also "print str(str)" and print "repr(str)" .
You should get the same thing for these others.

Why I say that is that it is possible to assign something in your code
to str then it's no-longer associated with the built-in function you
want, then it might not be callable. You could have done this in your
function, or in the global scope for example.

Thanks Anton. That was exactly it. I had a variable ealier in the
program called str. Changed that variable name to another, and the str()
function worked fine. DOH!

I knew it was something simple. Most of my fopahs are.

again, thanks,

Mathew
