python - Python 2 中的字符串替换和匹配

Question

我有一些用户帖子，我想将其与预定的模式列表相匹配(参见示例)。如果帖子与模式匹配，我想将帖子和模式写入文件。做这个的最好方式是什么？到目前为止，我只想到用 4 个 for 循环对其进行暴力破解，然后进行一些比较。我已经列出了我需要的所有数据，下面只是一些非常简单的示例，可以让您了解我正在寻找的内容。

示例

帖子:

posts =['When I ate at McDonald\'s, I felt sick.',
'I like eating at Burger King.',
'Wendy\'s made me feel happy.']

模式:

patterns = ['When I ate at [RESTAURANT]',
'I like eating at [RESTAURANT]',
'[RESTAURANT] made me feel [FEELING]',
'I felt [FEELING]']

列表:

restaurant_names = ['McDonald\'s', 'Burger King', 'Wendy\'s']

feelings = ['happy', 'sick', 'tired']

输出文件:

当我在[RESTAURANT]吃饭时，当我在麦当劳吃饭时，我感到恶心。

我感觉[FEELING]，当我在麦当劳吃饭时，我感到恶心。

[RESTAURANT]让我感到[FEELING]，Wendy's让我感到快乐。

我喜欢在[RESTAURANT]吃饭，我喜欢在汉堡王吃饭。

Answer 1

像这样怎么样:

>>> sentences = ["When I ate at McDonald's, I felt sick.", 'I like eating at Burger King.', 
    "Wendy's made me feel happy."]
>>> patterns = {"McDonald's": "[RESTAURANT]", "Burger King": "[RESTAURANT]", 
    "Wendy's": "[RESTAURANT]", "happy": "[FEELING]", "sick": "[FEELING]", 
    "tired": "[FEELING]"}

然后你就可以了

>>> for sentence in sentences:
...     replaced = sentence
...     for pattern in patterns:
...         if pattern in sentence:
...             replaced = replaced.replace(pattern, patterns[pattern])
...     print sentence
...     print replaced
...
When I ate at McDonald's, I felt sick.
When I ate at [RESTAURANT], I felt [FEELING].
I like eating at Burger King.
I like eating at [RESTAURANT].
Wendy's made me feel happy.
[RESTAURANT] made me feel [FEELING].

这仍然需要一些工作(例如，现在，单词 carsick 将变为 car[FEELING])，并且您可能希望避免所有重复通过创建另一个可以通过索引引用的替换文本列表来设置 patterns 值，但这也许足以让您开始？
