Python：如果URL文件中存在特定字符串，则打印一行
[英]Python: print a line if a specific string exists in the URL file
问题描述
I am writing a script in Python which should print the link to the sub-profile (01.m3u8, 02.m3u8, 108.m3u8, etc.). 
我正在用Python编写脚本，该脚本应将链接打印到子配置文件（01.m3u8、02.m3u8、108.m3u8等）。 This is my code: 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
The input stream is an HLS manifest file. 输入流是HLS清单文件。 This is the syntax of it: 这是它的语法：
#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
And when I run my script the output is: 当我运行脚本时，输出为：
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
I know that currently I am printing the whole line, but why then it reports: 我知道目前我正在打印整行，但是为什么会报告：
05.
m3u8
and not 05.m3u8 而不是05.m3u8

Apparently there is a m3u8 library in Python which can do exactly what I am looking for: 显然在Python中有一个m3u8库可以完全满足我的需求：
#!/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
