将文本中的变量名替换为该变量的值

Question

我有一个模板，它使用占位符来填充不同的内容。假设模板具有：

"This article was written by AUTHOR, who is solely responsible for its content."

作者的名字存储在变量author中。在

所以我当然会：

^{pr2}$

问题是我有10个自命名的变量，如果我可以这样做会更经济，为了简洁起见只使用4个：

def(self-replace):
    ...
    return

wholeThing = wholeThing.self-replace('AUTHOR', 'ADDR', 'PUBDATE', 'MF_LINK')

Answer 1

如果您可以控制模板，我将使用str.format和包含变量的dict：

>>> template = "This {publication} was written by {author}, who is solely responsible for its content."
>>> variables = {"publication": "article", "author": "Me"}
template.format(**variables)
'This article was written by Me, who is solely responsible for its content.'

很容易将其扩展到字符串列表：

^{pr2}$
