python - 属性错误: 'str' object has no attribute 'remove' ,如何修复？

Question

我创建了一个返回以下错误的函数:

original_alphabet.remove(value)
AttributeError: 'str' object has no attribute 'remove'

我不知道如何修复该错误，感谢任何帮助。这是我的代码:

def keyword_cipher_alphabet(keyword):
 original_alphabet = "abcdefghijklmnopqrstuvwxyz"

 for value in original_alphabet:
  if value in keyword:
   original_alphabet.remove(value)

 keyword_alphabet = ""
 for value in original_alphabet:
  keyword_alphabet += value 

 user_keyword = ""
 for value in keyword:
  user_keyword += value

 result = user_keyword + keyword_alphabet

 return result.upper()

Answer 1

导致该错误的原因是字符串没有方法remove。您可以尝试替换:

$> my_str = 'abc'
$> my_str = my_str.replace('b', '')
$> my_str
'ac'
