在python2默认编码是ASCII, python3里默认是unicode,转为其他的就用encode; encode,在转码的同时还会把string 变成bytes类型,decode在解码的同时还会把bytes变回string msg = "我爱北京天安门" msg_gb2312 = msg.encode("gb2312") #默认就是unicode,不用再decode,喜大普奔 gb2312_to_unicode = msg_gb2312.de...
chinese_characters=re.findall(r'[\u4e00-\u9fa5]+',text) 1. 解释一下这行代码: 正则表达式r'[\u4e00-\u9fa5]+'表示匹配一个或多个连续的汉字。 [\u4e00-\u9fa5]是一个Unicode字符范围,包含了所有的汉字。 现在,我们已经学习了如何从字符串中提取数字和汉字。让我们用一个饼状图来展示提取结果。 5...
说明'中文'.isalnum返回True,显然是因为'中文'.isalpha返回了True。而之所以.isalpha会返回True,是因为它判断的不仅仅是英文字母,而是所有Unicode里面,类别为letter的字符: str.isalpha[2] Return True if all characters in the string are alphabetic and there is at least one character, False otherwise. Alphabe...

Wanna get the unicode of chinese or vietnamese's han-nom and japanese characters I've tried these code text = "𬖰"; br = text.encode("unicode-escape"); print(br); and got b'\U0002c5b0' But what should I do when I want to have something like U+2C5B0 or U2C5B0 ? Wanna ge...
Unicode ordinals, strings, or None. The table must implement lookup/indexing via __getitem__, for instance a dictionary or list. If this operation raises LookupError, the character is left untouched. Characters mapped to None are deleted. ...
(2)、find()方法 作用:在字符串中查找子串,如果查找的子串在字符串之中,返回索引值,如果不在返回-1. 代码语言:javascript 复制 格式:str.find(‘查找的子串’,起点,终点) 其中的起点和终点可以不定义 举例: #不设置起点和终点进行查询 代码语言:javascript ...
(``str``, ``unicode``, ``int``, ``long``, ``float``, ``bool``, ``None``) will be skipped instead of raising a ``TypeError``. If ``ensure_ascii`` is true (the default), all non-ASCII characters in the output are escaped with ``\uXXXX`` sequences, and the result is...
<int> = ord(<str>) # Converts Unicode character to int.Use 'unicodedata.normalize("NFC", <str>)' on strings like 'Motörhead' before comparing them to other strings, because 'ö' can be stored as one or two characters. 'NFC' converts such characters to a single character, while ...
