Python:如何实现获取最新位置

目标:- 我需要用下面的输入解析一个文件，并在状态被批准并且构建日期是最新的时获取最新的(构建日期时间戳应该是最新的)位置。我提供了示例输入和输出，我有 perl 中的代码，新的python，请建议如何在python中实现这一点

INPUT:- 
Build:          M1234BAAAANAAW9321.1 
Location:       \\dreyers\builds468\INTEGRATION\M1234BAAAANAA9321.1

OUTPUT:-\\freeze\builds427\INTEGRATION\M1234BAAAANAA9321.3 

以下是实现的perl代码，我是python新手，请指教如何python化这段代码

$ echo 'Build:          M1234BAAAANAAW9321.1 
Location:       \\dreyers\builds468\INTEGRATION\M1234BAAAANAAW9321.1 
Comments:       Build completed, labeled, and marked for retention.

' | perl -e' 
 
local $/ = ""; 
my ( $build_date, $location ); 
while ( <> ) { 
next unless /status:\s+approved/i; 
my $date = sprintf "%04d%02d%02d%02d%02d%02d", ( /builddate:\s+(\d 
++)\D+(\d+)\D+(\d+)\D+(\d+)\D+(\d+)\D+(\d+)/i )[ 2, 0, 1, 3, 4, 5 ]; 
if ( !defined $build_date || $build_date lt $date ) { 
    ( $build_date, $location ) = ( $date, /location:\s+(.+)/i ); 
    }                                                            
}     

打印“$位置\n”； ' \freeze\builds427\集成\M1234BAAAANAAW9321.3

我尝试用 python 编写以下内容，似乎没有用，我想知道是否有更好的实现来实现目标..请建议

for line_info in lines: 
 
    line_info.find('Location') 
 
    if line_info.find('Location') == 0: 
        # Build Location 
        print "  Found Build location" 
        logString += "  Found Build location\n" 
        location = line_info.split(" ") 
        location1 = location[len(location)-1] 
    elif line_info.find('Status') == 0: 
        # Status 
        print "  Found Status" 
        logString += "  Found Status\n" 
        status = line_info.split(" ") 
        removeEmpty(status) 
        status1 = status[1].strip() 
        if status1 != "Approved" 
        goto .start 
    elif line_info.find('BuildDate') == 0: 
        # Main Make 
        print "  Found BuildDate" 
        logString += "  Found BuildDate\n" 
        builddate1 = line_info.split(" ") 
        removeEmpty(builddate1) 
        builddate1 = builddate1[1] 
        #if builddate1 >  

请您参考如下方法:

试试这段代码:

lastLocation = None 
lastTime = None 
skip = False 
 
bestLocation = None 
bestTime = None 
 
for line in text.split('\n'):     
    line.find('Location') 
    if line.find('Location') == 0: 
        # Build Location 
        skip = False 
        print "  Found Build location" 
        lastLocation = line.split(":")[1].lstrip()        
    elif line.find('Status') == 0: 
        # Status 
        print "  Found Status" 
        status = line.split(":") 
        status1 = status[1].strip() 
        if status1 != "Approved": 
            skip = True 
    elif line.find('BuildDate') == 0 and not skip: 
        # Main Make 
        print "  Found BuildDate" 
        timeStr = line.split(":", 1)[1].lstrip() 
        lastTime = datetime.datetime.strptime(timeStr, "%m/%d/%Y %H:%M:%S") 
        if bestTime == None or bestTime < lastTime: 
            bestTime = lastTime 
            bestLocation = lastLocation 
print lastLocation
