Question

我正在尝试创建一个程序，用于搜索我在单独文档中的文章。我无法让我的程序搜索该术语，并允许我查看仅包含搜索词的文档。理想情况下，我希望搜索输入类似于月亮，并允许我访问该文档。完整的文档看起来像这样，我的代码如下。

<NEW DOCUMENT>
Look on the bright 
side of Life.
<NEW DOCUMENT>
look on the very, dark
side of the Moon
<NEW DOCUMENT>
is there life
on the moon



search = input("Enter search words: ")
docs = []
document = []
doc_search = []

for line in file2:
    line = line.strip()
    if line == "<NEW DOCUMENT>":
        # start a new document
        document = []
        docs.append(document)
    else:
        # append to the current one
        document.append(line)
docs = ['\n'.join(document) for document in docs]

for line in docs:
    if line == search:
        doc_search = []
        doc_search.append(docs)

Answer 1

类似的东西：

docs=[]
with open("data1.txt") as f:
    lines=f.read().split("<NEW DOCUMENT>")[1:]
    for x in lines:
        docs.append(x.strip())
    print (docs)
search = input("Enter search words: ")   
for x in docs:
    if search in x:
        print ("{} found in:\t {}".format(search,x))

<强>输出：

['Look on the bright \nside of Life.', 'look on the very, dark\nside of the Moon', 'is there life\non the moon']
Enter search words: dark
dark found in:   look on the very, dark
side of the Moon

文档在python中从外部文件中搜索和检索
