Python learning-encoding conversion, python encoding conversionUnicode Note: Unicode is only a collection of symbols. It specifies the binary code of the symbols, but does not specify how to store the binary code. The Unicode encoding method refers to the Unicode Binary Code directly stored in the symbol.UTF-8 UTF-8 is the most widely used Unicode implementation method on the Internet. UTF-8 is a variable-length encoding method, which uses 1-4 bytes t

IP address acquisition and conversion, IP address acquisition and conversionIP address acquisition and conversion 1. Preface Converting an IP address to an integer storage is a major trend in database optimization. String indexes consume a lot of resources than integer indexes, especially when the data volume in a table is large, and query the data of an ip segment. The IP address mentioned in this article

Conversion and relationship between ArrayList and array, and arraylist array Conversion The main differences between arrays and ArrayList are efficiency, type recognition, and primitive type.Array ([]): the most efficient, but its capacity is fixed and cannot be changed dynamically;ArrayList: The capacity can be dynamically increased, but the efficiency is sacrificed;Suggestion:The array is used first. It

Java introduction (6) -- mutual conversion of set, basic data type, and reference data type, and mutual conversion of data type Set: 　　1. HashMap ----> class Overview: you can find the value through the key, the key is the key, and the values is the value. Feature: unordered values can be duplicate keys. Duplicate keys are not allowed. If duplicate keys are repeated, the values will be overwritten. Review:

How does MySQL select an appropriate engine and engine conversion ., Mysql engine Conversion How can we choose a suitable engine? Here is a simple sentence:"Unless some features not available in InnoDB are used and there is no other way to replace them, the InnoDB engine should be preferred." Unless you have to, we do not recommend that you use multiple storage engines together. Otherwise, a series of compl

P1032 String Conversion and p1032 String ConversionDescription It is known that there are two strings A, B and A set of string conversion rules (up to 6 Rules ): A1-> B1 A2-> B2 The meaning of the rule is: the sub-string A1 in A $ can be changed to B1, A2 can be changed to B2 .... For example, A = 'abc' B = 'xyz' The conversion rules are as follows: 'Abc'-> 'xu '
