Re: [Zope] Python Methods can't "construct literal dictionaries"?
This is one of the shortcomings of Python Methods that Scripts eliminate.
You can work around it by writing:
x = {}
x.update({y: z})

Here's an example of adding stuff to '_' using a monkey
patch Product.
Contents of __init__.py of directory Products/MoreBuiltins:
def _AddBuiltins():
from urllib import urlopen, quote, unquote
from base64 import decodestring, encodestring
def same_type(self, a, b):
return type(a)==type(b)
def attr_map(self, o):
r = o.__dict__.copy()
for k in r.keys():
if k[:1] == '_':
del r[k]
return r
class AnObject:
def __init__(self, **kw):
self.__dict__.update(kw)
NewBuiltins = {
'list': list,
'tuple': tuple,
'map': map,
'filter': filter,
'reduce': reduce,
'urllib': AnObject(open=urlopen, quote=quote,
unquote=unquote),
'base64': AnObject(decode=decodestring,
encode=encodestring),
'same_type': same_type,
'attr_map': attr_map,
}
from DocumentTemplate.DT_Util import TemplateDict
TemplateDict.__dict__.update(NewBuiltins)
#call it
_AddBuiltins()

'lambda' is actually a keyword, not a function, and hence works fine in PM0.1.7. 'map()', 'filter()', et al., were deemed to be susceptible to being used in DOS attacks, and hence are not permitted in through-the-web code (they would need to be added to the '_' namespace, like 'str()', et aliae).

Re: [Zope] Python Methods Vote
Just view the poll again. Everything but "python method" has been getting trounced so far. How come "python function" isn't there, again ?

Re: [Zope] Python Methods Vote
I have the opposite problem. Having voted once - early yesterday - I now can't vote again. The reason I want to vote again is that I have changed my mind! Now I want to _poll down_ "Python Method" and add a new alternative "ZPython Method" or add some points to "Python Script" or "ZPY".
