为什么不利用这个简单的函数:

def remove_characters(str, chars_list):
    for char in chars_list:
        str = str.replace(char, '')
  
    return str

使用功能:

print(remove_characters('A.B!C?', ['.', '!', '?']))

输出:

ABC

''.join(c for c in myString if not c in badTokens)

最近我在钻研scheme，现在我觉得我擅长递归和求值。哈哈哈。分享一些新的方法:

首先，求值

print eval('string%s' % (''.join(['.replace("%s","")'%i for i in replace_list])))

第二，递归

def repn(string,replace_list):
    if replace_list==[]:
        return string
    else:
        return repn(string.replace(replace_list.pop(),""),replace_list)

print repn(string,replace_list)

嘿，别投反对票。我只是想分享一些新的想法。

删除* % @ !从下面的字符串:

s = "this is my string,  and i will * remove * these ** %% "
new_string = s.translate(s.maketrans('','','*%,&@!'))
print(new_string)

# output: this is my string  and i will  remove  these  

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'

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]
