Hi Everyone,

Hello

I am fairly new to Zope and I need some assitance on something that I know is fundamental so please don't beat up on me too bad ;-)

I haven't been a member of this list for too terribly long, but the folks here seem to be pretty darn friendly.

I am try to open a file with a Python Script in Zope for content manipulation. This is a text file, I basically want to read a number, operate on it and write it back out. However when I try to get my file handle I get;

You are going to need to use an External Method (or a Product) for this. The Zope based Python scripts only offer a "safe" subset of Python. Opening files on the filesystem is not a part of this "safe" subset.

file=open("/home/chris/misernumber", "r+")

Zope Error

Zope has encountered an error while publishing this resource.

Error Type: NameError Error Value: global name 'open' is not defined

I tried creating the file as a Zope object but I get the same error. Again I know this is fundamental. If ya'll can help me with this, or at least point me to some documentation it would be deeply appreciated.

There probably is a way to do this with Zope objects, but it wouldn't be using open(). There is a whole slew of methods for manipulating Zope objects, check the Zope API section in the Zope Book. Depending on what you are actually trying to do there might be a more Zope-like way of accomplishing it than with the External Method hammer, but without knowing what you are trying to do it is hard to guess what that more Zope-like thing should be.
