WebThe hashCode() method returns the hash code of a string. The hash code for a String object is computed like this: s[0]*31^(n-1) + s[1]*31^(n-2) + ... + s[n-1] where s[i] is the ith character of the string, n is the length of the string, and ^ indicates exponentiation. Syntax public int hashCode() Parameter Values. WebJan 21, 2024 · Hash functions like SipHash24 have a costly initialization and finalization code that can dominate speed of the algorithm for very short strings. On the other hand, Python calculates the hash value of short strings quite often. A simple and fast function for especially for hashing of small strings can make a measurable impact on performance.
