python:字符串中提取特定的数据

在日志文件中有一大堆，格式相同的文本，需要提取出接口耗时的时间

>>> 运单号:71742507538566,快递100接口耗时:8,返回结果:[{"lengthPre":14,"comCode":"huitongkuaidi","noPre":"717425","noCount":59622}] >>> 运单号:71679940955921,快递100接口耗时:7,返回结果:[{"lengthPre":14,"comCode":"huitongkuaidi","noPre":"716799","noCount":65664},{"lengthPre":14,"comCode":"shentong","noPre":"716799","noCount":1}] >>> 运单号:4601476769218,快递100接口耗时:10,返回结果:[{"lengthPre":13,"comCode":"yunda","noPre":"460147","noCount":284021}] >>> 运单号:4601470516612,快递100接口耗时:9,返回结果:[{"lengthPre":13,"comCode":"yunda","noPre":"460147","noCount":284021}] >>> 运单号:71716941576703,快递100接口耗时:8,返回结果:[{"lengthPre":14,"comCode":"huitongkuaidi","noPre":"717169","noCount":175244}] >>> 运单号:75308510292636,快递100接口耗时:11,返回结果:[{"lengthPre":14,"comCode":"zhongtong","noPre":"753085","noCount":630547}] >>> 运单号:75308440358906,快递100接口耗时:8,返回结果:[{"lengthPre":14,"comCode":"zhongtong","noPre":"753084","noCount":812745}] >>> 运单号:75308594459656,快递100接口耗时:7,返回结果:[{"lengthPre":14,"comCode":"zhongtong","noPre":"753085","noCount":630547}] >>> 运单号:777004640509373,快递100接口耗时:10,返回结果:[{"lengthPre":15,"comCode":"shentong","noPre":"777004","noCount":497868}] >>> 运单号:4301913501825,快递100接口耗时:8,返回结果:[{"lengthPre":13,"comCode":"yunda","noPre":"430191","noCount":848444}] >>> 运单号:70095194774559,快递100接口耗时:7,返回结果:[{"lengthPre":14,"comCode":"huitongkuaidi","noPre":"700951","noCount":18888}] >>> 运单号:777004084932865,快递100接口耗时:7,返回结果:[{"lengthPre":15,"comCode":"shentong","noPre":"777004","noCount":497868}] >>> 运单号:773011564374916,快递100接口耗时:7,返回结果:[{"lengthPre":15,"comCode":"shentong","noPre":"773011","noCount":8552066},{"lengthPre":15,"comCode":"pfcexpress","noPre":"773011","noCount":8028}] >>> 运单号:75308509589096,快递100接口耗时:7,返回结果:[{"lengthPre":14,"comCode":"zhongtong","noPre":"753085","noCount":630547}] >>> 运单号:4301909414706,快递100接口耗时:7,返回结果:[{"lengthPre":13,"comCode":"yunda","noPre":"430190","noCount":1322407},{"lengthPre":13,"comCode":"tcxbthai","noPre":"430190","noCount":3}]
