need help with my append syntax

[yaffa]

dear folks,

i'm trying to append a semicolon to my addr string and am using the
syntax below. for some reason the added on of the ; doesn't work.
when i print it out later on it only shows the original value of addr.

addr = incident.findNe xtSibling('td')
addr.append('%s ;')

thanks

Is addr is really a string? AFAIK, strings havn't an append methond.

use += to extend strings:

..>>> addr = 'abc'
..>>> addr += '%s;'
..>>> addr
'abc%s;'

I'm usually annoyed by IDEs because, for instance, they don't use VIM
as an editor. Since I'm hooked to that, all IDEs I've used so far have
failed to impress me.

or

addr2 = '%s;' % addr

Strings, being immutable, do not support appending like lists do. Also,
the %whatever specifiers are only in effect when used with the string
formatting operator (%).

Do not discuss off-list, maybe others will have better solutions to your
question. And also please do not top-posting, it makes me difficult to
trim the irrelevant text.

sorry addr is a variable. how to i append to that?
I know addr is a variable (or better a name). But what object do you
assign to it? I mean, does incident.findNe xtSibling('td') return a
string or an object of another type?

If your code "addr.append('% s;')" doesn't raise an exception, it is
pretty sure what assigned to addr is not a string (maybe a list, which
has an "append" method). You can use "print addr" or "print repr(addr)"
to determine that.

Python strings don't have a 'append' method.

"doesn't work" is the worst possible description of a problem.
Please read

addr = incident.findNe xtSibling('td')
addr.append('%s ;')
If you don't have an AttributeError here then addr is not bound to a string.
thanks
