One thing we might want to know, given an input to a chatbot, is if the input is a question.
We are going to use a very simple heuristic to check this: we will consider any input that has a question mark ('?') in it to be a question.
To do so, write a function called is_question.
This function should have the following inputs, outputs, and internal procedures:
Input(s): input_string - string
Output(s): output - boolean
Procedure(s): if there is a '?' in input_string, set output to True
otherwise, set output to False.
return output

Following are the code to this question:

def is_question(input_string): # defining method is_question  

   output = '?' in input_string # checking question mark symbol in value

   return output #return value

input_string = input('Enter any string value: ') # defining variable input_string to input value

print (is_question(input_string)) # call method and print return value

Output:

Enter any string value: what is your name?

True

Explanation:

In the given python program code, a method "is_question" is declared, which accepts an "input_string" value in its parameter.

this is false i think

if it is a true or false question
