Hi there.
I have defined a class called Item with several (about 30 I think)
different attributes (is that the right word in this context?). An
abbreviated example of the code for this is:
class Item(object):
def __init__(self, height, length, function):
params = locals()
del params['self']
self.__dict__.update(params)
def __repr__(self):
all_items = self.__dict__.items()
return '%s,%s,%s' % (self.height, self.length, self.function)
I have a csv file that I use to store and retrieve all the info about
each Item, one item per line.
I have written a little peice of python that lets me search through all
Items (after reading them into a variable called all_items) and will
return matching results:
for item in all_items:
strItem = str(item)
m = re.search(p[i], strItem, flags = re.I)
if m:
height = getattr(item, "height")
length = getattr(item, "length")
function = getattr(item, "function")
print "height is %s, length is %s and function is %s" % height,
length, function
This has the limitation of only working over a single search item. I
want to be able to search over an uncontrollable number of search
strings because I will have people wanting to search over 2, 3 or even
(maybe) as many as 5 different things.
I was thinking that I would try to write a function that created a
sublist of Items if it matched and then run subsequent searches over
the subsequent search strings using this sublist.
I am not entirely sure how to store this subset of Items in such a way
that I can make searches over it. I guess I have to initialize a
variable of type Item, which I can use to add matching Item's to, but
I have no idea how to do that....(If it was just a list I could say
"sublist = []", what do I use for self defined classes? I Am also
usure how to go about creating a function that will accept any number
of parameters.
Any assistance with these two questions will be greatly appreciated!
Thanks!
