在python中，有没有一种方法可以从两个端点之间的日志文件打印数据

Question

我有一个日志文件，正在尝试打印两个日期之间的数据

2020-01-31T20:12:38.1234Z, asdasdasdasdasdasd,...\n
2020-01-31T20:12:39.1234Z, abcdef,...\n
2020-01-31T20:12:40.1234Z, ghikjl,...\n
2020-01-31T20:12:41.1234Z, mnopqrstuv,...\n
2020-01-31T20:12:42.1234Z, wxyzdsasad,...\n

这是示例日志文件，我想打印2020-01-31T20:12:39到2020-01-31T20:12:41之间的行

到目前为止，我已经设法找到并打印了开始日期行。我已经过了开始日期

with open("logfile.log") as myFile:
    for line in myFile:
        linenum += 1
        if line.find(start) != -1:
            print("Line " + str(linenum) + ": " + line.rstrip('\n'))

但是我怎么能一直打印到截止日期呢

Answer 1

答案不是python，而是bash

sed -n '/2020-01-31T20:12:38.1234Z/,/2020-01-31T20:12:41.1234Z/p' file.log

输出：

2020-01-31T20:12:38.1234Z, asdasdasdasdasdasd,...\n
2020-01-31T20:12:39.1234Z, abcdef,...\n
2020-01-31T20:12:40.1234Z, ghikjl,...\n
2020-01-31T20:12:41.1234Z, mnopqrstuv,...\n
