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
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 ;)
Thanks all.
