Double quotes in (Python) strings (was: Problem with escaped double quotes)
by Dieter Maurer 19 Nov '00

Inside Python strings, i.e. inside expr="'...'", you can use "\042" or "\x22" to embed a '"'. How it works: Python recognizes various escapes inside strings. Usually, they are used to insert characters that otherwise are difficult to include (usually, because they are unprintable or there is not widely knows key on the standard keyword). For your purpose, two escape types are interesting: octal escapes and hexadecimal excapes. An octal escape is a "\" followed by up to 3 octal digits. The octal digits are interpreted as an octal number defining the code of the character to be embedded. A hexadecimal excape is a "\x" followed by a sequence of hexadecimal digits. Python takes the last two digits, interprets it as a hexadecimal number defining the code of the character to be embedded. The code for '"' is octal 042 and hexadecimal 0x22. Dieter

Maybe you can get the missing pieces from DC. If not or you are in a hurry: * fetch the Python source (--> www.python.org) * configure it to enable threads: ./configure --with-threads * make and install it: make install * fetch Zope's source distribution * build it with you Python Dieter

You find them with "ZopeFind" (-> built-in API documentation), and delete them with "manage_delObjects" (-> built-in API documentation) (you may need nested "ZopeFind"s as "manage_delObjects" is a folder method). You can automate this be an external script (-> HowTo on zope.org) Dieter

Problem with escaped double quotes

Aitor asked: > My problem is this : > > <dtml-let foo=3D" ' blaublau : " fdsaf " df ' "> > </dtml-let> > > It doesn't work 'cause I can't escape the doble quotes inside the string= > I'm trying to eval. > > Any solution??? If I recall correctly, the work around I've used is to store the text, including the double quotes, as a property of a parent folder, so that it can be found by acquisition. for example, create a String Property named "fdsaf_alias" with a value of : " fdsaf " and then change your DTML to : <dtml-let foo=3D" ' blaublau : " + fdsaf_alias + " df ' "> Other than that, reconsider whether there might be a way to do this with single quotes. HTML will usually accept either single or double quotes, but nesting quotes is of course the common reason to use both types in an expression. Since I have no idea what the item actually represents, it's not a call I can make from this end. Good Luck! Jery S.

Still More Problems On the Install...

Hi; Okay, I've untarred the distro. The instructions said to type in *python w_pcgi.py*. Did so and lots of stuff printed to screen, the last of which was *SystemError 512*. Should I worry about that? Then I thought I was supposed to type in *./start* but it didn't recognize that command. I'm running Python 2.2.2. Thanks for your help. BenO

Stupid Installation Question

Hi; Okay, hope I did this right... Installed Zope in a directory at doc root (called zope) and untarred it. Now I have a directory called Zope-2.2.2-src with a bunch of stuff in it. What do I do from here? How do I see it working? TIA, BenO
