首先将参数1,2,3打包,打包前1,2,3明显属于python数据类型中的integer,pack后就变成了C结构的二进制串,转成 python的string类型来显示就是 '\x01\x00\x00\x00\x02\x00\x03'。由于本机是小端('little- endian',关于大端和小端的区别请参照这里,故而高位放在低地址段。i 代表C struct中的int类型,故而本机...
For the end user, a tuple or struct_time is of no use. You can use the asctime() function to convert a time tuple or struct_time to a string in a human-readable format. Let’s use the previous example to display UTC time in a human-readable format: import time current_time_tuple...

Using Python Objects The dict option is a great way to emulate pointers in Python, but sometimes it gets tedious to remember the key name you used. This is especially true if you’re using the dictionary in various parts of your application. This is where a custom Python class can really...
Here is my fast implementation of a reverse complement function in C: https://gist.github.com/alexpreynolds/4f75cab4350e9d937f4a You might be able to use this directly in Python via thesubprocesslibrary. Outsourcing the reverse complement step to a utility writ...
Python 2.7 is planned to be the last of the 2.x releases, so we worked on making it a good release for the long term. To help with porting to Python 3, several new features from the Python 3.x series have been included in 2.7....
A notable limitation of the Python 3.5 implementation is that it was not possible to use await and yield in the same function body. In Python 3.6 this restriction has been lifted, making it possible to define asynchronous generators: async def ticker(delay, to): """Yield numbers from 0 to...
The core MicroPython includes implementation of several standard Python 3.4 libraries, which consists of an array, binascii, builtins, cmath, collections, errno, gc, hashlib, heapq, io, json, math, os, random, re, select, socket, ssl, struct, sys, time, uasyncio, zlib, and _thread. Oth...
