删除一大串特殊字符

Question

我要从文档中删除以下每个特殊字符：

symbols = {`,~,!,@,#,$,%,^,&,*,(,),_,-,+,=,{,[,],},|,\,:,;,",<,,,>,.,?,/}

我之所以不这么做是因为：

document = re.sub(r'([^\s\w]|_)+', '', document)

如果文件是用波兰语等语言编写的，我也会用这种方式删除许多（重音/特殊）字母

如何在一个表达式中删除上面的每个特殊字符？你知道吗

Answer 1

您可以通过使用^{}在不使用正则表达式的情况下解决此问题：

symbols = {"`", "~", "!", "@", "#", "$", "%", "^", "&", "*", "(", ")", "_", "-", "+", "=", "{", "[", "]", "}", "|", "\\", ":", ";", "\"", "<", ",", ">", ".", "?", "/"}

for c in symbols:
    document = document.replace(c, "")

Answer 2

symbols = ['a', 'b', '|']
document = document.translate({ord(c):None for c in symbols})

Answer 3

如果您想逐字删除每个字符，可以使用str.replace和string模块：

a = '345l,we.gm34mf,]-='

for char in string.punctuation:
    a = a.replace(char, '')
a

'345lwegm34mf'

如果需要更多的符号来替换（string.punctuation等于'!"#$%&\'()*+,-./:;<=>?@[\\]^_{|}~'), you can add them to ain`string。你知道吗
