The search speed of the list decreases as the element increases.However, dict search speed is not without cost,dict The disadvantage is that the memory is large,

Dict Python has a built-in dictionary: dict support, Dict full name dictionary, also known as a map in other languages, using key-value (Key-value) storage, with extremely fast lookup speed. For example, suppose you want to find the corresponding results according to your classmates ' names, and if you use list, you need two list: names = [' Michael ',

For the questions raised in the previous article, this time answer:As can be seen from the rehash process, ht[0] and ht[1] have entries in the rehash process, i.e. all entries in the dictionary are distributed in Ht[0] and ht[1],And then the trouble came out. The main problems are as follows: (now how to solve the problem)1. How to find key.2. How to insert a new key.3. How to delete a key.4. How to ensure that the rehash process constantly inserts, deletes entries, and rehash no errors.5. How t

Redis's memory storage structure is a large dictionary storage, which is also known as a hash table. Redis can store tens of thousands of records of CACHE and tens of millions or even hundreds of millions of records (depending on the memory), which fully demonstrates Redis's powerful buffer. The core data structure of Redis is the dictionary (dict). During the process of increasing data volume, dict will en
