program code optimization usually includes: Reduce the size of the code, improve the efficiency of the Code. This allows the program to run faster. Here's a concrete discussion of Python code optimization techniques. Improved algorithm, select appropriate data structure
. Dictionary and list) The hash table is used in the Python dictionary, so the complexity of the query operation is O (1), while the list is actually an array. in the list, the query needs to traverse the entire list, the complexity is O (n), so the operation dictionaries such as searching and accessing members are faster than list. Listing 1. Code dict. py from time import time t = time() list = ['a','b

Procedures for the execution of Python programsAs we all know, the C language needs to compile the source code into an executable binary before executing it, that is, translating the source code into machine code, which, once generated, can be used for execution. But is python

Josh Triplett began his speech at Pycon 2015 with a "laugh point": porting Python without operating system: He and his Intel colleagues let the interpreter run on the Grub boot, BIOS, or EFI system. He has a lot of interesting things to say, and a lot of demos that are open to the eyes of the audience.The original idea of Python running on boot loader was the ability to test hardware, like BIOS, Extensible

Regardless of the language, we need to pay attention to performance optimization problems, improve execution efficiency. Choosing a scripting language will endure its speed, which in some way illustrates the inadequacy of Python as a scripting language, which is that execution efficiency and performance are not bright enough. Although Python has never been as fast as C and Java, many
