如何从列表的句子中移除@开头或包含https的指定单词？

Got it, let's fix your code to achieve exactly what you need—removing only the unwanted words (not entire sentences) from your list. Here's the complete implementation:

Step-by-Step Code #

First, let's start with your original list and process each sentence individually:

# Your original list of sentences
res = ['Today is a great day', 'lunch @myplace', 'make sure to check this link: https://']

# Process each sentence to filter out unwanted words
cleaned_sentences = []
for sentence in res:
    # Split the sentence into individual words
    words = sentence.split()
    # Keep only words that don't start with @ and don't contain 'https'
    filtered_words = [word for word in words if not word.startswith('@') and 'https' not in word]
    # Join the filtered words back into a proper sentence
    cleaned_sentences.append(' '.join(filtered_words))

# Let's see the result!
print(cleaned_sentences)

Output #

Running this code will give you:

['Today is a great day', 'lunch', 'make sure to check this link:']

One-Liner Version (if you prefer conciseness) #

You can also condense this into a single list comprehension for brevity:

cleaned_sentences = [' '.join([word for word in s.split() if not word.startswith('@') and 'https' not in word]) for s in res]

Bonus: Case-Insensitive HTTPS Check #

If you need to handle cases where 'HTTPS' is in uppercase (like HTTPS://example.com), modify the filter condition to use lowercase for the check:

filtered_words = [word for word in words if not word.startswith('@') and 'https' not in word.lower()]

This way, any variation of 'https' (uppercase, mixed case) will be caught and the corresponding word removed.
