mystring.translate(string.maketrans(","),string.punctuation)不与Unicode字符串(发现辛苦) marcmaxson @工作:myString.translate(str.maketrans("","", string.punctuation))是Unicode字符串在Python 3。虽然只在string.punctuation包括ASCII标点。点击链接在我以前的评论。它显示如何删除所有标点(包括Unicode One)。
import string print(string.digits) 执行结果: 0123456789 #punctuation:生成所有标点符号。 import string print(string.punctuation) 执行结果: !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~ 13.openpyxl 13.1 读Excel from openpyxl import load_workbook wb = load_workbook("files/p1.xlsx") sheet = wb...
Return a Unicode string of one character with ordinal i; 0 <= i <= 0x10ffff. 返回Unicode码位对应的字符的字符串格式。码位范围是 0~1114111(16 进制表示是 0x10FFFF),超过这个范围,会触发 ValueError 异常。该函数是 ord() 的逆函数。 chr(97) 'a' ord('a') 97 chr(1114111) '\U0010ffff' ...
Unicode vs UTF-8 It didn’t take long for people to realize that all of the world’s characters could not be packed into one byte each. It’s evident from this that modern, more comprehensive encodings would need to use multiple bytes to encode some characters. You also saw above that ...
美国人制定了一套编码,用于描述英语中的字符和这 8 位二进制数的对应关系,这被称为 ASCII 码。 ASCII 码一共定义了 128 个字符 128 个字符只使用了 8 位二进制数中的后面 7 位,最前面的一位统一规定为 0 万国码Unicode:规定了世界上所有的字符都对应一个唯一的编号 ...
python3默认的字符编码是unicode,默认的文件编码是utf-8。 在python2里,将string处理为原生的bytes类型。 python3把字符串的编码改成了unicode, 还把str和bytes做了明确区分, str就是unicode格式的字符,bytes是单纯二进制。 print语句没有了,取而代之的是print()函数。 在python 2.x中/除法整数相除的结果是一个...
