如何从python文件中读取下一行或下一行的单词?(How to read next word or words till next line from file in python?)

我想在匹配单词后从一行读取单词:

确切地说 - 我有一个文件如下:

-- Host: localhost
-- Generation Time: Nov 15, 2006 at 09:58 AM
-- Server version: 5.0.21
-- PHP Version: 5.1.2

我想搜索一下,如果该文件包含'服务器版本:'子字符串,如果然后读取'服务器版本:'之后的下一个字符直到下一行,在这种情况下为'5.0.21'。

我尝试了以下代码,但它给出了下一行( - PHP版本:5.1.2)而不是下一个单词(5.0.21)。

with open('/root/Desktop/test.txt', 'r+') as f:
    for line in f:
        if 'Server version:' in line:
            print f.next()

i'm trying to read words from a line after matching words :

To be exact - I have a file with below texts:

-- Host: localhost
-- Generation Time: Nov 15, 2006 at 09:58 AM
-- Server version: 5.0.21
-- PHP Version: 5.1.2

I want to search that, if that file contains 'Server version:' sub string, if do then read next characters after 'Server version:' till next line, in this case '5.0.21'.

I tried the following code, but it gives the next line(-- PHP Version: 5.1.2) instead of next word (5.0.21).

with open('/root/Desktop/test.txt', 'r+') as f:
    for line in f:
        if 'Server version:' in line:
            print f.next()

最满意答案

在映射之前,只需使用选择器在两个表中选中复选框:

var boxes  = $('input:checkbox:checked', '#MainContent_CBLFYSubjects, #MainContent_CBLSYSubjects'),
    subjes = $.map(boxes, function(el){
        return el.value;
    });

Just use a selector that selects checkboxes in both tables before you map them :

var boxes  = $('input:checkbox:checked', '#MainContent_CBLFYSubjects, #MainContent_CBLSYSubjects'),
    subjes = $.map(boxes, function(el){
        return el.value;
    });
