ASCII码(American Standard Code for Information Interchange)是一种用于在计算机和电信设备中使用的字符编码标准。它使用7位或8位二进制数来表示字符,共计128个字符,包括英文字母、数字、标点符号和一些控制字符。 在Python中,我们可以使用内置的ord()函数将一个字符转换为对应的ASCII码值,也可以使用
在计算机编程中,ASCII(American Standard Code for Information Interchange)码是一种用来表示文本字符的编码标准。每个字符都被赋予一个唯一的ASCII码值,从0到127。在Python中,我们可以通过内置的ord()函数将一个字符转换为其对应的ASCII码值,也可以通过chr()函数将一个ASCII码值转换为对应的字符。 ASCII码的基本原...
在CPython3.3之后,字符串对象发生了根本性的变法,本篇我们来讨论一下字符串对象,在Include/unicodeobject.h,在整个源代码的官方文档可以归纳出几点。在CPython3.3+之后,Unicode字符串分为有4种 紧凑型ASCII(Compact ASCII) 紧凑型ASCII也称为ASCII限定字符串(ASCII only String).其对应PyASCIIObject结构体,该对象使用...
我尽量写得通俗易懂,希望能对其他朋友有用。毕竟,字符编码是计算机技术的基石,想要熟练使用计算机,就必须懂得一点字符编码的知识。 一、ASCII 码 我们知道,计算机内部,所有信息最终都是一个二进制值。每一个二进制位(bit)有0和1两种状态,因此八个二进制位就可以组合出256种状态,这被称为一个字节(byte)。也就是...
ASCII stands for the "American Standard Code for Information Interchange". It was designed in the early 60's, as a standard character set for computers and electronic devices. ASCII is a 7-bit character set containing 128 characters.
用Python 2.x会经常碰到一个错误: UnicodeEncodeError: 'ascii' codec can't encode character ... : ordinal not in range(128) 搞清这个问题之前要先理解三个知识点: UTF-8 vs Unicode Encoding vs Decoding Python 2.7里的 str 和 unicode 1. UTF-8 vs Unicode ...

ensure_ascii表示的意思是将python数据类型解析为json格式时是否需要转为ASCII码,如果打开(默认打开即为True),那么python数据类型转为json字符串后的中文会变成ASCII编码; 如果将其设置为False,则python数据类型解析为json时,不会变为ASCII编码,而是保持其默认显示即中文格式。
