I am experiencing a problem when i am creating AI assistant

When i am writing code-

It is showing unknown value error.
I am unable to understand what is the problem

It should take command but showing error, I am learning python by making basic Assistant that takes command and execute it.

import speech_recognition as sr
import os


def say(text):
   os.system(f"say {text}")

def takecommand():
   mic=sr.Recognizer()
   with sr.Microphone() as source:
       mic.pause_threshold = 1
       audio=mic.listen(source)
       query=mic.recognize_google(audio, language="eng-in")
       print(f"User said {query}")
       return query


if __name__== '__main__':
   print("VS CODE")
   say("Hii My Name is JARVIS A.I.")
   print("Listening...")
   text=takecommand()
   say(text)
