Telegram Bot Clickable Command with Parameters

I am using python-telegram-bot to create a Telegram bot.

I am trying to insert a command with parameters into bot messages, such that a user could press it?

Here, on telegram core page I found a pic that depics a chat with command + parameters (/dl_)

However I cannot get how this can be done

Check out this closed issue: https://github.com/python-telegram-bot/python-telegram-bot/issues/696

The concept is pretty simple:

/dl_

Quick working solution for you:

#!/usr/bin/python3
from telegram.ext import Updater, MessageHandler, Filters
from telegram.ext import RegexHandler
from string import ascii_lowercase
from string import digits
from random import choice
from sys import exc_info as error

token = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'


def start(bot, update):
username = update.message.from_user.first_name
update.message.reply_text(greeting(username), parse_mode='Markdown')
message = genre_head()

for genre in genres:
message += genre_list(genre['name'], genre['id'])

update.message.reply_text(message, parse_mode='Markdown')

def artist(bot, update):
genre_id = update.message.text.replace('/dl_', '')

for genre in genres:
if genre['id'] == genre_id:
message = artist_head(genre['name'])

for artist in artists:
message += artist_list(artist['id'], artist['name'], genre_id)

message += artist_list_end()
update.message.reply_text(message, parse_mode='Markdown')

def download(bot, update):
file = update.message.text.replace('/dl_', '')
update.message.reply_text(u'U0001F3BCnhttp://music.com/{}.mp3'.format(file),
parse_mode='Markdown')

try:
updater = Updater(token)
dp = updater.dispatcher

dp.add_handler(RegexHandler('/start', start))
dp.add_handler(RegexHandler('^(/dl_[d]+)$', artist))
dp.add_handler(RegexHandler('^(/dl_[d]+[w]+)$', download))
dp.add_handler(MessageHandler(Filters.text, start))

updater.start_polling()
except:
print(error())
updater.stop()
