Does anyone know how to add row numbers?

I can open this file directly from the net,and I want to add row numbers to each line based on rules. If you need header row number,then start from number 1, if no need, then start from next line. This is my code, I tried a lot but doesn't work. It looks like picture. Does anyone how to solve this problem? Thanks in advance!
import sys
class Main:
def task1(self):
print('*' * 30, 'Task')
import urllib.request
# url
url = 'http://www.born.nhely.hu/group_list.txt'
# Initiate a request to get a response
while True:
try:
response = urllib.request.urlopen(url)
except Exception as e:
print('An error has occurred, the request is being made again, the error message is as follows：', e)
else:
break
# Print all student information
content = response.read().decode('utf-8')
#add row number
header_row = input("Do you want to know header_row numbers? Y OR N?")
if header_row == 'Y':
for i, line in enumerate(content, start=1):
print(f'{i},{line}')
else:
for i, line in enumerate(content, start=0):
print('{},{}'.format(i, line.strip()))
def start(self):
self.task1()
Main().start()

Have a look at the data you are downloading:
Name;Short name;Email;Country;Other spoken languages
ABOUELHASSAN Shehab Ibrahim Adbelazin;?;dwedar909#gmail.com;?;?
AGHAEI HOSSEIN ABADI Mohammad Mehdi;Matt;mahdiaghaei355#gmail.com;Iran;English
...
Now look at the results you are getting:
1,N
2,a
3,m
4,e
5,;
6,S
7,h
8,o
...
It should be apparent that you are looping character by character; not line by line.
When you have:
for i, line in enumerate(content, start=1):
print(f'{i},{line}')
content is a string -- not a list of lines -- so you will loop over the string character by character with the for loop.
So to fix, do:
for i, line in enumerate(content.splitlines(), start=1):
print(f'{i},{line}')
Or, you can change the method of reading from the server to reading lines instead of characters:
content = response.readlines()

Your absorbing the .txt content in one big string... if you use .readlines() instead of .read(), you can achieve what you want.
You should modify this:
# Print all student information
content = response.read().decode('utf-8')
To this:
# Print all student information
content = response.readlines()
You can use the repr() method to take a look at your data:
print(repr(content))

Also, instead of hard-coding the charset as utf-8, you can use response.headers.get_content_charset()

how to convert google-maps GeoJSON to GPX, retaining location names

I have exported my google-maps Point Of Interests (saved places / locations) via the takeout tool. How can i convert this to GPX, so that i can import it into OSMAnd?
I tried using gpsbabel:
gpsbabel -i geojson -f my-saved-locations.json -o gpx -F my-saved-locations_converted.gpx
But this did not retain the title/name of each point of interest - and instead just used names like WPT001, WPT002, etc.

in the end I solved this by creating a small python script to convert between the formats.
This could be easily adapted for specific needs:
#!/usr/bin/env python3
import argparse
import json
import xml.etree.ElementTree as ET
from xml.dom import minidom
def ingestJson(geoJsonFilepath):
poiList = []
with open(geoJsonFilepath) as fileObj:
data = json.load(fileObj)
for f in data["features"]:
poiList.append({'title': f["properties"]["Title"],
'lon': f["geometry"]["coordinates"][0],
'lat': f["geometry"]["coordinates"][1],
'link': f["properties"].get("Google Maps URL", ''),
'address': f["properties"]["Location"].get("Address", '')})
return poiList
def dumpGpx(gpxFilePath, poiList):
gpx = ET.Element("gpx", version="1.1", creator="", xmlns="http://www.topografix.com/GPX/1/1")
for poi in poiList:
wpt = ET.SubElement(gpx, "wpt", lat=str(poi["lat"]), lon=str(poi["lon"]))
ET.SubElement(wpt, "name").text = poi["title"]
ET.SubElement(wpt, "desc").text = poi["address"]
ET.SubElement(wpt, "link").text = poi["link"]
xmlstr = minidom.parseString(ET.tostring(gpx)).toprettyxml(encoding="utf-8", indent=" ")
with open(gpxFilePath, "wb") as f:
f.write(xmlstr)
def main():
parser = argparse.ArgumentParser()
parser.add_argument('--inputGeoJsonFilepath', required=True)
parser.add_argument('--outputGpxFilepath', required=True)
args = parser.parse_args()
poiList = ingestJson(args.inputGeoJsonFilepath)
dumpGpx(args.outputGpxFilepath, poiList=poiList)
if __name__ == "__main__":
main()
...
it can be called like so:
./convert-googlemaps-geojson-to-gpx.py \
--inputGeoJsonFilepath my-saved-locations.json \
--outputGpxFilepath my-saved-locations_converted.gpx

There is also a NPM script called "togpx":
https://github.com/tyrasd/togpx
I didn't try it, but it claims to keep as much information as possible.

How to add SYLT(synced lyrics) tag on ID3v2 mp3 file using python?

I want to add synced lyrics from vtt on my mp3 file using python. I tried using the mutagen module but it didn't work as intended.
from mutagen.id3 import ID3, USLT, SLT
import sys
import webvtt
lyrics = webvtt.read(sys.argv[2])
lyri = []
lyr = []
for lyric in lyrics:
times = [int(x) for x in lyric.start.replace(".", ":").split(":")]
ms = times[-1]+1000*times[-2]+1000*60*times[-3]+1000*60*60*times[-4]
lyri.append((lyric.text,ms))
lyr.append(lyric.text)
fil = ID3(sys.argv[1])
tag = USLT(encoding=3, lang='kor', text="\n".join(lyr)) # this is unsynced lyrics
#tag = SLT(encoding=3, lang='kor', format=2, type=1, text=lyri) --- not working
print(tag)
fil.add(tag)
fil.save(v1=0)
How can I solve this problem?

I use mutagen to parse an mp3 file that already has SYLT data, and found the usage of SYLT:
from mutagen.id3 import ID3, SYLT, Encoding
tag = ID3(mp3path)
sync_lrc = [("Do you know what's worth fighting for", 17640),
("When it's not worth dying for?", 23640), ...] # [(lrc, millisecond), ]
tag.setall("SYLT", [SYLT(encoding=Encoding.UTF8, lang='eng', format=2, type=1, text=sync_lrc)])
tag.save(v2_version=3)
But I can't figure out format=2, type=1 means.

check
https://id3.org/id3v2.3.0#Synchronised_lyrics.2Ftext
format 1: Absolute time, 32 bit sized, using MPEG frames as unit
format 2: Absolute time, 32 bit sized, using milliseconds as unit
type 0: is other
type 1: is lyrics
type 2 : is text transcription
type 3 : is movement/part name (e.g. "Adagio")
type 4 : is events (e.g. "Don Quijote enters the stage")
type 5 : is chord (e.g. "Bb F Fsus")
type 6 : is trivia/'pop up' information

Python configparser reads comments in values

ConfigParser also reads comments. Why? Shouldn't this be a default thing to "ignore" inline comments?
I reproduce my problem with the following script:
import configparser
config = configparser.ConfigParser()
config.read("C:\\_SVN\\BMO\\Source\\Server\\PythonExecutor\\Resources\\visionapplication.ini")
for section in config.sections():
for item in config.items(section):
print("{}={}".format(section, item))
The ini file looks as follows:
[LPI]
reference_size_mm_width = 30 ;mm
reference_size_mm_height = 40 ;mm
print_pixel_pitch_mm = 0.03525 ; mm
eye_cascade = "TBD\haarcascade_eye.xml" #
The output:
C:\_Temp>python read.py
LPI=('reference_size_mm_width', '30 ;mm')
LPI=('reference_size_mm_height', '40 ;mm')
LPI=('print_pixel_pitch_mm', '0.03525 ; mm')
LPI=('eye_cascade', '"TBD\\haarcascade_eye.xml" #')
I don't want to read 30 ;mm but I want to read just the number '30'.
What am I doing wrong?
PS: Python3.7

hi use inline_comment_prefixes while creating configparser object check example below
config = configparser.ConfigParser(inline_comment_prefixes = (";",))
Here is detailed documentation.

The link of the page I am scraping contains the third character, but when I copy it becomes the link above.
I am not sure about the encoding.
import re
html = 'source of page'
matches = re.findall('ls_main = \[\[.*?;', html)[0]
matches = matches.decode('unknown encoding').encode('utf-8')
How can I put the original character in the string of the link ?
I use Python 2.7.

%XX encoding can be done using urllib.qutoe:
>>> import urllib
>>> urllib.quote('英冠')
'%E8%8B%B1%E5%86%A0'
>>> urllib.quote(u'英冠'.encode('utf-8')) # with explicit utf-8 encoding.
'%E8%8B%B1%E5%86%A0'
To get back the original string, use urllib.unquote:
>>> urllib.unquote('%E8%8B%B1%E5%86%A0')
'\xe8\x8b\xb1\xe5\x86\xa0'
>>> print(urllib.unquote('%E8%8B%B1%E5%86%A0'))
英冠
In Python 3.x, use urllib.parse.quote, urllib.parse.unquote:
>>> import urllib.parse
>>> urllib.parse.quote('英冠', encoding='utf-8')
'%E8%8B%B1%E5%86%A0'
>>> urllib.parse.unquote('%E8%8B%B1%E5%86%A0', encoding='utf-8')
'英冠'
