python Programming Glossary: perturbOverriding Python's Hashing Function in Dictionary http://stackoverflow.com/questions/13514716/overriding-pythons-hashing-function-in-dictionary slot 14 and it's not the integer 45 then the slot value is perturbed until an empty slot is found or the same key is found instead... key is found instead. Perturbing is done with the formula perturb slot hash while slot_is_full and item_in_slot_is_not_equal_to_key.. and item_in_slot_is_not_equal_to_key slot 5 slot 1 perturb perturb 5 So when there is a collision another slot is picked..
How is the return value of __hash__ used? http://stackoverflow.com/questions/14493204/how-is-the-return-value-of-hash-used hashvalue 0 hashvalue hashvalue i hashvalue mask yield i perturb hashvalue while True i 5 i perturb 1 0xFFFFFFFFFFFFFFFF yield.. hashvalue mask yield i perturb hashvalue while True i 5 i perturb 1 0xFFFFFFFFFFFFFFFF yield i mask perturb PERTURB_SHIFT For.. while True i 5 i perturb 1 0xFFFFFFFFFFFFFFFF yield i mask perturb PERTURB_SHIFT For example the dictionary d 'timmy' 'red' 'barry'..
Why is early return slower than else? http://stackoverflow.com/questions/8271139/why-is-early-return-slower-than-else To resolve this Python calculates Starting with j hash 32 perturb hash Repeat this until we find a free slot j 5 j 1 perturb perturb.. perturb hash Repeat this until we find a free slot j 5 j 1 perturb perturb 5 use j 2 i as the next table index which gives it 17.. hash Repeat this until we find a free slot j 5 j 1 perturb perturb 5 use j 2 i as the next table index which gives it 17 to use..
