Problem with hash function: hash(1) == hash(1.0)
- by mtasic
I have an instance of dict with ints, floats, strings as keys, but the problem is when there are a as int and b as float, and float(a) == b, then their hash values are the same, and thats what I do NOT want to get because I need unique hash vales for this cases in order to get corresponding values.
Example:
d = {1:'1', 1.0:'1.0', '1':1, '1.0':1.0}
d[1] == '1.0'
d[1.0] == '1.0'
d['1'] == 1
d['1.0'] == 1.0
What I need is:
d = {1:'1', 1.0:'1.0', '1':1, '1.0':1.0}
d[1] == '1'
d[1.0] == '1.0'
d['1'] == 1
d['1.0'] == 1.0
