Telegram bots commands regex handler (python)

telegram_bots_commands_regex

##Regex
`regex_patern = r'^\/(command)+(\@username_of_bot\w*(_\w+)*)?([ \f\n\r\t\v\u00A0\u2028\u2029].*)?$'`
Commands like that will handle
/command
/command arg1 arg2 ...
/command@username_of_bot
/command@username_of_bot arg1 arg2 ...

but
/command@other_bot
/command@other_bot arg1 arg2 ...
won't handle

###Function with regex

```
def commands(*args, bot_username='username_of_bot'):
    """Returns regex based commands' parser for telegram"""
    return '|'.join([i for i in [
        rf'^\/({i})+(\@{bot_username}\w*(_\w+)*)?([ \f\n\r\t\v\u00A0\u2028\u2029].*)?$' for i in args
    ]])
```

###Telethon example
```
@client.on(events.NewMessage(pattern=commands("start", "help"))
async def start(event):
	print(evet)
```

###Pyrogram example
```
@app.on_message(filters.regex(commands("start", "help")))
async def start(client, message):
	print(message)
```
