the information includes the character's name, its category, the numeric value if applicable (for characters representing numeric concepts such as the Roman numerals, fractions such as one-third and four-fifths, etc.). There are also display-related properties, such as how to use the code poin...
Handling Unicode characters is a critical aspect of modern programming, especially in a globalized environment where software applications need to support multiple languages and character sets. Python, being a widely-used language, provides several methods to handle and display Unicode characters. This ar...

先说一下python中的字符串类型,在python中有两种字符串类型,分别是str和unicode,他们都是basestring的派生类;str类型是一个包含Characters represent (at least) 8-bit bytes的序列;unicode的每个unit是一个unicode obj;所以: len(u'中国')的值是2;len('ab')的值也是2; ...
首先我们来了解正则表达式的精确匹配和模糊匹配,其中模糊匹配又包括匹配符号(Matching Characters)和特殊序列(Special Sequence)。 精确匹配 精确匹配很好理解,即明文给出我们想要匹配的模式,比如上面讲到的在思科24口的2960交换机里查找up的端口,我们就在管道符号|后面明文给出模式'up',又比如我们想在下面的交换机日志...
我还在 YouTube 上发布了一个73 秒的视频,这样你就可以看到它们运行时 macOS Finder 窗口显示保存的标志。这些脚本正在从fluentpython.com下载图片,该网站位于 CDN 后面,因此在第一次运行时可能会看到较慢的结果。示例 20-1 中的结果是在多次运行后获得的,因此 CDN 缓存已经热了。
First, when you want to display Unicode characters in Windows console, you have to select a font able to display them. Similarly, if you want to enter Unicode characters, you have to have you keyboard properly configured. This has nothing to do with Python, but is included here for complet...

comments — although the standard library only uses ASCII characters for identifiers, a convention that any portable code should follow. To display all these characters properly, your editor must recognize that the file is UTF-8, and it must use a font that supports all the characters in the ...
