Python:如果URL文件中存在特定字符串，则打印一行

Question

我正在用Python编写一个脚本，它应该打印到子配置文件(01.m3u8、02.m3u8、108.m3u8等)的链接。这是我的代码：

#!/usr/bin/env python

from urllib import quote
import requests

input_file = quote(raw_input("Please enter the input file path: "), safe=':''/')

read_file = requests.get(input_file, verify = False)
for line in read_file:
        if "m3u8" in line:
                print line

输入流是HLS清单文件。下面是它的语法：

#EXTM3U
#EXT-X-VERSION:4
#EXT-X-INDEPENDENT-SEGMENTS
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio",NAME="deu_1",DEFAULT=YES,AUTOSELECT=YES,LANGUAGE="deu",URI="06.m3u8"
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio",NAME="deu_2",DEFAULT=NO,AUTOSELECT=YES,LANGUAGE="deu",URI="07.m3u8"
#EXT-X-MEDIA:TYPE=SUBTITLES,GROUP-ID="subs",NAME="DEU_32_149",DEFAULT=NO,AUTOSELECT=YES,LANGUAGE="DEU",URI="108.m3u8"
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=206701,RESOLUTION=320x180,FRAME-RATE=12.500,AUDIO="audio",SUBTITLES="subs"
01.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=681504,RESOLUTION=320x180,FRAME-RATE=25.000,AUDIO="audio",SUBTITLES="subs"
02.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=1243460,RESOLUTION=480x270,FRAME-RATE=25.000,AUDIO="audio",SUBTITLES="subs"
03.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=1917808,RESOLUTION=960x540,FRAME-RATE=25.000,AUDIO="audio",SUBTITLES="subs"
04.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=3532769,RESOLUTION=1280x720,FRAME-RATE=50.000,AUDIO="audio",SUBTITLES="subs"
05.m3u8

当我运行我的脚本时，输出是：

LECT=YES,LANGUAGE="deu",URI="06.m3u8"
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio",NAME="deu_2",DEFAULT=NO,AUTOSELECT=YES,LANGUAGE=
"deu",URI="07.m3u8"
#EXT-X-MEDIA:TYPE=SUBTITLES,GROUP-ID="subs",NAME="DEU_32_149",DEFAULT=NO,AUTOSELECT=YES,LANGUAGE="DEU",URI=
"108.m3u8"
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=206701,RESOLUTION=320x180,FRAME-RATE=12.500,AUDIO="audio",SUBTITLES="subs"

01.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=681504,RESOLUTION=320x180,FRAME-RATE=25.000,AUDIO="audio",SUBTITLES="subs"
0
2.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=1243460,RESOLUTION=480x270,FRAME-RATE=25.000,AUDIO="audio",SUBTITLES="subs"
03
.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=1917808,RESOLUTION=960x540,FRAME-RATE=25.000,AUDIO="audio",SUBTITLES="subs"
04.
m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=3532769,RESOLUTION=1280x720,FRAME-RATE=50.000,AUDIO="audio",SUBTITLES="subs"
05.
m3u8

我知道目前我打印的是整行代码，但是为什么它会报告：

05.
m3u8

而不是05.m3u8

Answer 1

显然，Python语言中有一个m3u8库，它可以做我正在寻找的事情：

#!/usr/bin/env python
from urllib import quote
import m3u8

input_file = quote(raw_input("Please enter the input file path: "), safe=':''/')

m3u8_main = m3u8.load(input_file)
for playlist in m3u8_main.playlists:
        print playlist.uri
