I have rather simple 'Address' object that contains streetname,
number, my own status and x,y coordinates for it. I have two lists
both containing approximately 30000 addresses.
I've defined __eq__ method in my class like this:
def __eq__(self, other):
return self.xcoord == other.xcoord and \
self.ycoord == other.ycoord and \
self.streetname == other.streetname and \
self.streetno == other.streetno
But it turns out to be very, very slow.
Then I setup two lists:
list_external = getexternal()
list_internal = getinternal()
Now I need get all all addresses from 'list_external' that are not in
'list_internal', and mark them as "new".
I did it like this:
for addr in list_external:
if addr not in list_internal:
addr.status = 1 # New address
But in my case running that loop takes about 10 minutes. What I am
doing wrong?
