现在我们的hash table变成: 【概念4: load factor (载荷因子) 】λ=number_of_keys/table_size. 在上述例子中,我们存放了6个items, hash table的长度为11, 则其对应的载荷因子为6/11。 当我们想要查找一个key的时候,我们只需要利用hash function算出相应的存储位置(slot name) ,查看该位置是否存储了key。这...
A string object in Python is represented internally by the structure PyStringObject.“ob_shash” is the hash of the string if calculated. “ob_sval” contains the string of size “ob_size”. The string is null terminated. The initial size of “ob_sval” is 1 byte and ob_sval[0] = ...

return x as the hash If you run hash(‘a’) in Python, it will execute string_hash() and return 12416037344. Here we assume we are using a 64-bit machine. If an array of size x is used to store the key/value pairs then we use a mask equal to x-1 to calculate...
I had an interesting realization tonight: I'm terrified of hash tables. Specifically, my work on JRuby (and even more directly, my work optimizing JRuby) has made me terrified to ever consider using a hash table in the hot path of any program or piece of
The purpose of the importlib package is two-fold. One is to provide the implementation of the import statement (and thus, by extension, the __import__() function) in Python source code. This provides an implementation of import which is portable to any Python interpreter. This also provides...

libgit2is used in a variety of places, from GUI clients to hosting providers ("forges") and countless utilities and applications in between. Because it's written in C, it can be made available to any other programming language through "bindings", so you can use it inRuby,.NET,Python,...
This advantage can be used (1) to extract bits from fingerprints and use these bits for indexing or improving the time complexity of operations (2) because the fingerprints are allocated in a bucket, the two single hash functions of the filter can be used to determine beforehand which ...
