Chapter 2: Creating the J.A.R.V.I.S. Core – The Heart of Your Assistant
Now that your tools are ready and you've said your first “Hello, world,” it’s time to build the brain of your assistant—the core loop that listens to your commands and acts accordingly.

2.1 What Is a Command Loop?
Think of it like a conversation.
You say something → J.A.R.V.I.S. listens → Processes it → Responds or executes a task.
In Python, this is done with a while loop that keeps running unless you tell it to stop.
---
2.2 Let's Code It
Open your terminal and edit your script:
nano jarvis.py
Clear everything and enter this:
import time
print("Initializing J.A.R.V.I.S....")
time.sleep(1)
print("Hello, I am J.A.R.V.I.S. Online and ready.")
# Start command loop
while True:
command = input("You: ").lower()
if "time" in command:
current_time = time.strftime("%I:%M %p")
print("J.A.R.V.I.S.: The time is", current_time)
elif "exit" in command or "bye" in command:
print("J.A.R.V.I.S.: Going offline. Goodbye, sir.")
break
else:
print("J.A.R.V.I.S.: Sorry, I didn't understand that.")

2.3 What This Does
Greets the user
Waits for input with input("You: ")
Responds to keywords like "time" or "bye"
Keeps running unless “exit” or “bye” is entered
---
2.4 Try It Out
Run your script:
python jarvis.py
Try saying:
What is the time?
Exit
Hello

2.5 Your First Custom Commands
Let’s add a few more responses:
elif "hello" in command:
print("J.A.R.V.I.S.: Hello sir, how can I assist you today?")
elif "who are you" in command:
print("J.A.R.V.I.S.: I am your virtual assistant. Just like the one Tony Stark built.")
Now it feels more personal—just like talking to your own digital companion.
