如果您只是尝试提取整个“ Training Objectives”（训练目标）块，请寻找关键字并保持追加行，直到您击中空白行（或其他合适的标记，例如下一个标题）。

（已编辑以处理多个文件和关键字）

const regex = /^\/search\/((?:\d{4}))(?:\/((?:\d|1[012]|0[1-9])))?(?:\/((?:[0-3]\d)))/
const testLink = [
  '/search/2017/02/03/category/gun/','/search/2017/01/category/gun/','/search/2017/category/gun/','/search/2017/02/03/category/gun/','/search/2018/?category=gun&type%5B%5D=sendo'

]

testLink.forEach((value,i) => {
  console.log(value.replace(regex,''))
  console.log('-------------------')
})

这假定每个文件中只需要1个块。如果您要从每个文件中提取多个块，它将变得更加复杂。

如果您确实总是且每次都需要5行，那么您可以执行类似的操作，但添加一个计数器来计数5行。

尝试一下：

with open('test.txt') as f:
    content = f.readlines()
index = [x for x in range(len(content)) if 'training objectives' in content[x].lower()]
for num in index:
    for lines in content[num:num+5]:
        print (lines)

如果您只有几个字（只是为了获取索引）：

index = []
for i,line in enumerate(content):
    if 'hello' in line or 'there' in line:     //add your or + word here
        index.append(i)
print(index)

如果您有很多（只是为了获取索引）：

list = ["hello","there","blink"]    //insert your words here
index = []
for i,line in enumerate(content):
    for items in list:
        if items in line:
            index.append(i)
print(index)

这取决于您所处的位置，但是我将正则表达式放在一起可能有助于举例说明我的文本在变量st中的显示方式：

In [254]: st
