我正在努力理解以下列表理解

Question

可以请某人用简单的 for 循环和语句编写以下列表理解。

new_words = ' '.join([word for word in line.split() if not 
any([phrase in word for phrase in char_list])])

我在下面的代码中写了上面的列表理解，但它不起作用。

new_list = []
for line in in_list:
  for word in line.split():
    for phrase in char_list:  
        if not phrase in word:
          new_list.append(word)
return new_list

谢谢

Answer 1

new_words = ' '.join(
    [
        word for word in line.split() 
        if not any(
            [phrase in word for phrase in char_list]
        )
    ]
)

或多或少相当于：

new_list = []
for word in line.split():
    phrases_in_word = []
    for phrase in char_list:
        # (phrase in word) returns a boolean True or False
        phrases_in_word.append(phrase in word)  
     
    if not any(phrases_in_word):
        new_list.append(word)

new_words = ' '.join(new_list)

Answer 2

new_words = ' '.join([word for word in line.split() 
                      if not any([phrase in word for phrase in char_list])])

相当于：

lst = []
for word in line.split(): 
    for phrase in char_list: 
        if phrase in word:
            break
    else:  # word not in ANY phrase
        lst.append(word)
new_words = ' '.join(lst)
