对于Python 3 str或Python 2 unicode值，str.translate（）只使用字典；在该映射中查找代码点（整数），并删除映射到None的任何内容。

要删除（某些？）标点符号，请使用：

import string

remove_punct_map = dict.fromkeys(map(ord, string.punctuation))
s.translate(remove_punct_map)

dict.fromkeys（）类方法使创建映射变得简单，根据键的顺序将所有值设置为None。

要删除所有标点符号，而不仅仅是ASCII标点符号，您的表需要稍微大一点；参见J.F.Sebastian的答案（Python 3版本）：

import unicodedata
import sys

remove_punct_map = dict.fromkeys(i for i in range(sys.maxunicode)
                                 if unicodedata.category(chr(i)).startswith('P'))

with open('one.txt','r')as myFile:

    str1=myFile.read()

    print(str1)


    punctuation = ['(', ')', '?', ':', ';', ',', '.', '!', '/', '"', "'"] 

for i in punctuation:

        str1 = str1.replace(i," ") 
        myList=[]
        myList.extend(str1.split(" "))
print (str1) 
for i in myList:

    print(i,end='\n')
    print ("____________")

myString.translate(None, string.punctuation)

在不太严格的情况下，单行线可能会有所帮助：

''.join([c for c in s if c.isalnum() or c.isspace()])

您也可以这样做：

import string
' '.join(word.strip(string.punctuation) for word in 'text'.split())

显然，我无法对所选答案进行编辑，所以这里有一个适用于Python3的更新。在进行非平凡转换时，转换方法仍然是最有效的选择。
