敏感词文本文件 filtered_words.txt，里面的内容 和 0011题一样，当用户输入敏感词语，则用 星号 * 替换，例如当用户输入「北京是个好城市」，则变成「**是个好城市

代码:

def filtered_words(path=‘filtered_words.txt‘):
    words = []
    with open(path, ‘r‘, encoding=‘utf-8‘, newline=‘‘)  as f:
        for line in f:
            words.append(line.strip())
    return words

def main():
    words = filtered_words()
    while True:
        #注意 python3中input相当于python2中raw_input
        text = input(‘content: ‘).strip()

        for word in words:
            if word in text:
                replace_str = ‘*‘ * len(word)
                text = text.replace(word,replace_str)
        print(text)
