替换python

Question

我有txt文件，每行包含一个单词（ library.txt ），如：

Word1
Word2

第二个txt 文件如下所示：

I have got many words. 
I know Word1 is very interesting.
ButWord2 is awful because its connected with another word.
I think there is no Word3 at all.

我需要在第二个txt 文件中的 library.txt 中搜索这些字词并替换它们，以便它们看起来像这样：

I have got many words. 
For example <font=yellow>Word1</font> is very interesting.
But<font=yellow>Word2</font> is awful because its connected with another word.
I think there is no Word3 at all.

我有这样的代码，但它不起作用：

rules =[]
with open(library, 'r') as libraryfile:
    for line in libraryfile:
        rules.append(line.rstrip())

with open(second', 'r') as secondfile:
    with open(third', 'w') as thirdfile:
        for line in secondfile:
            if all(rule in line for rule in rules):
                thirdfile.write(line.replace(rule, '<font color=yellow>'+rule+'</font>'))
            else:
                thirdfile.write(line)

Answer 1

首先，您必须使用any而不是all。因为您希望其中至少有一个人在rules进行更改。 然后rule未在if之外定义，另外您可能会在rules中添加line中的多个单词，因此最好迭代rules需要时更换。这给出了：

with open(second, 'r') as secondfile:
    with open(third, 'w') as thirdfile:
        for line in secondfile:
            if any(rule in line for rule in rules):
                for r in rules:
                    line = line.replace(r, '<font color=yellow>'+r+'</font>')
            thirdfile.write(line)

Answer 2

您希望any代替all，因为rules中的一个单词就足以显示在一行中。
