with open("forbidden_words.txt", "r", encoding="utf-8") as stop, open(f'{input()}', 'r', encoding='utf-8') as file:
    stop_words = stop.readline().split(" ")
    text_file = file.readline()
    for i in stop_words:
        text_file = re.sub(i, '*'*len(i), text_file, flags=re.IGNORECASE)
    print(text_file)

我有以下问题：我的代码没有替换所有需要替换的东西，我应该在我的代码中替换什么来修复它？

Answer 1

with open("forbidden_words.txt", encoding="utf-8") as file, open(input()) as infile:
    text = infile.read()
    for f in file.read().strip("\n").split():
        pos = text.lower().find(f)
        while pos > -1:
            text = text[:pos] + "*" * len(f) + text[pos+len(f):]
            pos = text.lower().find(f)
print(text)

Answer 2

当你需要使用 readlines 推荐时，你使用了 readline 命令。

另外，我建议你尝试使用更有意义的名称，这是最佳实践（阅读这篇文章以了解为什么https://towardsdatascience.com/data-scientists-your-variable-names-are-awful-heres-how-to-fix-them-89053d2855be）

例如，您的代码应该看起来更像这样：

with open("forbidden_words.txt", "r", encoding="utf-8") as forbidden_file, open(f'{input()}', 'r', encoding='utf-8') as input_file:
    forbidden_words = forbidden_file.readline().split(" ")
    text_file = input_file.readline()
    for forbidden_word in forbidden_words:
        text_file = re.sub(forbidden_word, '*'*len(i), text_file, flags=re.IGNORECASE)
    print(text_file)
