The problem is that I don't understand this code that I
exactly copied from a Web page tutorial. Can you folks point
me to tutorials where I can learn to comprehend this code?
Specifically, the line in question. How is it that one can
code "params[key]" (what does that mean?) and the other
side, what does that mean
I think you are gathering more fans Victor :)
http://docs.python.org/tutorial/datastructures.html#dictionaries
This still isn't telling me what I need to know. Perhaps I'm missing
the point, as in the recent case with putting the "print cookie"
statement in the header. I am assuming (translation: making an a$$
out of you and me) that "params[key] automatically assigns the
fieldStorage key to the newly created params key in the dict of the
same, and assigning the value from the cgi.FieldStorage of that key
to the params value. Is that correct?
TIA,

I may have answered my own question. I have this:
def cgiFieldStorageToDict(fieldStorage):
params = {}
for key in fieldStorage.keys():
params[key] = fieldStorage[key].value
return params
Which is what Recipe 81547 actually says!
dict = cgiFieldStorageToDict(cgi.FieldStorage())
print dict
which gave me this:
{'store': 'products', 'cat': 'prodCat1'}
which looks about right. I would have written the code like this:
keys = []
values = []
for key, value in fieldStorage.iteritems():
keys.append(key)
values.append(value)
params = dict(zip(keys, values))
which obviously isn't as elegant. But that's what I knew. Learned
another trick, I guess ;)
If that works then so should this:
params = dict(fieldStorage.iteritems())
