我认为这是足够简单和将做!

list = [",",",","!",";",":"] #the list goes on.....

theString = "dlkaj;lkdjf'adklfaj;lsd'fa'dfj;alkdjf" #is an example string;
newString="" #the unwanted character free string
for i in range(len(TheString)):
    if theString[i] in list:
        newString += "" #concatenate an empty string.
    else:
        newString += theString[i]

这是一种方法。但是如果你厌倦了保留一个你想要删除的字符列表，你实际上可以通过使用你迭代的字符串的顺序号来做到这一点。订单号是该字符的ASCII值。0作为字符的ASCII码是48，小写z的ASCII码是122，所以:

theString = "lkdsjf;alkd8a'asdjf;lkaheoialkdjf;ad"
newString = ""
for i in range(len(theString)):
     if ord(theString[i]) < 48 or ord(theString[i]) > 122: #ord() => ascii num.
         newString += ""
     else:
        newString += theString[i]

在Python 3.8中，这适用于我:

s.translate(s.maketrans(dict.fromkeys(',!.;', '')))

也许有一种更现代、更实用的方式来实现你的愿望:

>>> subj = 'A.B!C?'
>>> list = set([',', '!', '.', ';', '?'])
>>> filter(lambda x: x not in list, subj)
'ABC'

请注意，对于这个特定的目的，它是相当夸张的，但一旦您需要更复杂的条件，过滤器就会派上用场

Python 3，单行列表综合实现。

from string import ascii_lowercase # 'abcdefghijklmnopqrstuvwxyz'
def remove_chars(input_string, removable):
  return ''.join([_ for _ in input_string if _ not in removable])

print(remove_chars(input_string="Stack Overflow", removable=ascii_lowercase))
>>> 'S O'

如果您正在使用python3并寻找翻译解决方案-函数已更改，现在接受1个参数而不是2个参数。

该参数是一个表(可以是字典)，其中每个键都是要查找的字符的Unicode序数(int)，值是替换值(可以是要将键映射到的Unicode序数或字符串)。

下面是一个用法示例:

>>> list = [',', '!', '.', ';']
>>> s = "This is, my! str,ing."
>>> s.translate({ord(x): '' for x in list})
'This is my string'
