How to properly split a string?

Question

Python

There is such a code. Let's say the user sent us "choose 1 or 2". Everything works, the bot selects one option, but as soon as the user increases the number of words in the option, the bot does not work correctly (selects the word "or" or only part of the option). How to properly split a string? If we make the word "or" as a separator, then how to exclude the word "choose" from the first option so that the bot does not send us "I choose choose 1"

If it is impossible, then how to replace it?

text = event.obj['text'].split(' ')
                   if text[0] == "Выбери" or text[0] == "выбери":
                       list = [text[1], text[3]]
                       change = random.choice(list)
                       vk.method("messages.send",
                                 {
                                     "chat_id": event.object.peer_id - 2000000000,
                                     "message": "Я выбираю " + f'{change}',
                                     "random_id": random.randint(1, 2147483647)
                                 })

Answer 1

I thought a little and shared. If anyone needs

text_1 = event.obj['text'].split(' ', maxsplit=1)
                   if text_1[0] == "Выбери" or text_1[0] == "выбери":
                       text_2 = text_1[1].split('или')
                       list = [text_2[0], text_2[1]]
                       change = random.choice(list)
                       vk.method("messages.send",
                                 {
                                     "chat_id": event.object.peer_id - 2000000000,
                                     "message": "Я выбираю " + f'{change}',
                                     "random_id": random.randint(1, 2147483647)
                                 })

Answer 2

No way.
Threat only require a more or less strict input format from the user.

Answer 3

Use regular expressions as an option:

import re
import random

if "выбери" in event.obj['text'].lower():
    variants_list = re.findall('\d+', event.obj['text'])
    if 'или' in event.obj['text'].lower():
         change = random.choice(variants_list)
         
...

Answer 4

>>> stop_words = ['выбери', 'или']
>>> input_text_list = input_text.split()
>>> target_words_list = [word for word in input_text_list if word.lower() not in stop_words]

PS

list =

You should not use Python built-in names ( see dir(__builtins__) ) as your variable names.

if text[0] == "Choose" or text[0] == "choose":

When comparing in the context of upper/lower cases, simply cast the corresponding objects to the same case, for example:
if text[0].lower() == "выбери":

Answer 5

You can split a string using the work method.
WITH strings In particular, the split method Designed to work with lists.
having a list
xx = ['1;2;3;4']
text.split(';')
text = list.
split() method
';' character between lines.
