Question

我想通过检查文本文件中的行数在Text前面的每一行中写入时间，因为我想将此文本文件转换为此链接后的.srt文件。 https://unix.stackexchange.com/questions/111024/how-to-convert-a-txt-subtitle-file-to-srt-format

每行是1秒。（第一行从00:00:00开始：）我的文件有很多行（500-1000行）来自

.......Text......... (first line)
.......Text......... (second line)
.......Text......... (third line)
    .
    .
    .
.......Text......... (60 line)
.......Text......... (61 line)
    .
    .
.................... (3600 line)

对此

00:00:01:.......Text......... (first line)
00:00:02:.......Text......... (second line)
00:00:03:.......Text......... (third line)
    .
    .
    .
00:01:00:.......Text......... (60 line)
00:01:01:.......Text......... (61 line)
    .
    .
01:00:00:.................... (3600 line)

我想检查行号并在每行前面写上文字，但是我的代码中存在逻辑错误，无法检查行号并在该行打开文件写入文本。我不知道如何编写循环并比较行数。我不是这个菜。

def numberline(fname):
    with open(fname) as f:
           for i, l in enumerate(f):
                  pass
    return i + 1
numberline("/home/pi/gtest.txt")) 

dataFile = open("/home/pi/gtest.txt", "w")
    for line in range(numberline("/home/pi/gtest.txt")):
dataFile.write("00:00:%02d:\n" % line)
    dataFile.close()

尝试一下（假设a.txt是一个包含多行的文本文件）

import datetime


def make_time(num_of_seconds):
    hours = 0 if num_of_seconds < 3600 else num_of_seconds / 3600
    minutes = 0 if num_of_seconds < 60 else (num_of_seconds - hours * 3600) / 60
    seconds = num_of_seconds - (minutes * 60) - (hours * 3600)
    t = datetime.time(hours,minutes,seconds)
    return t.strftime("%H:%M:%S")


new_lines = []
with open('a.txt', 'r') as f_in:
    lines = f_in.readlines()
for idx, line in enumerate(lines):
    new_lines.append('{}:{}'.format(make_time(idx), line))
for l in new_lines:
    print(l.strip())

如何在给定文件中的给定行号上附加时间？
