How do I fix this code?

Question

I want the program to detect at least 1 out of 2 possible elements in a sentence so it can determine that it is a question, before it shoots out an appropriate answer.

import re, random

questions = ['do you', 'did you']
question_sign = ['?']
yes_no = ['yes', 'no']
confused = ["I don't know what you mean!"]

pattern1 = re.compile('|'.join(r'(\b' + question + r'\b)' for question in questions))
pattern2 = re.compile('|'.join(r'(\b' + questionsign + r'\b)' for questionsign in question_sign))

if pattern1.search(input().lower() in questions) or pattern2.search(input().lower()) in question_sign:
print (random.choice(yes_no))

else:
print(random.choice(confused))

Answer 1

No need to go for regexp here, python has nice builtin functions to deal with this.

sentence = input().lower()
is_question = any(sentence.endswith(s) for s in question_sign) or any(sentence.startswith(s) for s in questions)

You need to save the input once in a variable, otherwise the program will expect a new input every time you compare.
