Object Integer mapping
Need help on python version 3.1.x. I can't seem to know what going on
a bit. The code that I check that the hash is different every time. Is
there a way to make the hash the same? I using as to check the class
is the same variables but if it different variable in the class that
it add to the array and return the index.
# Generic Object->Integer mapping
# the object must be usable as a dictionary key
class ObjMap:
def __init__(self):
self.dict = {}
self.next = 0
def get(self, obj):
if obj in self.dict:
return self.dict[obj]
else:
id = self.next
self.next = self.next + 1
self.dict[obj] = id
return id
def items(self):
getval = operator.itemgetter(0)
getkey = operator.itemgetter(1)
return map(getval, sorted(self.dict.items(), key=getkey))
class Point:
def __init__(self):
self.x = 0
self.y = 0
self.z = 0
points = ObjMap()
Testme = Point()
Testme.x = 0
print(points.get(Testme))
Testme2 = Point()
Testme2.y = 1
print(points.get(Testme2))
Testme3 = Point()
Testme3.y = 1
print(points.get(Testme3))
Ttestme4 = Point()
Ttestme4.y = 1
print( points.get(Ttestme4))
It keep adding new array from this but doesn't match hash. Need help
on how to fix this class code.

I am not sure how to use struct package.
Here an example for the input:

socket policy flash help
I need help on the policy to able to let access to user to the server

example, but I got no luck. Using python version 3.1.
Here the code I tested but it not working.
if str(buff) == str("b\'\\x00\'"):
print ('policy FOUND >>> sending...')

I try that method and flash socket is not getting the policy.
b = b''
self.sockfd.send(b);
server = socket.socket( socket.AF_INET, socket.SOCK_STREAM)
When it able to read the policy it send it but it fail to send to
flash some reason and send it again and then d/c.
