class IntelligentPersonalAssistant:
    def __init__(self):
        pass
 
    def tell_time(self):
        now = datetime.datetime.now()
        print(f"Current time: {now.strftime('%H:%M:%S')}")
 
    def open_website(self, url):
        webbrowser.open(url)
        print(f"Opened website: {url}")
 
    def demo(self):
        self.tell_time()
        self.open_website('https://www.python.org')
 
if __name__ == "__main__":
    print("Intelligent Personal Assistant Demo")
    assistant = IntelligentPersonalAssistant()
    assistant.demo()
 

import datetime
import webbrowser
 
class IntelligentPersonalAssistant:
    def __init__(self):
        pass
 
    def tell_time(self):
        now = datetime.datetime.now()
        print(f"Current time: {now.strftime('%H:%M:%S')}")
 
    def open_website(self, url):
        webbrowser.open(url)
        print(f"Opened website: {url}")
 
    def demo(self):
        self.tell_time()
        self.open_website('https://www.python.org')
 
if __name__ == "__main__":
    print("Intelligent Personal Assistant Demo")
    assistant = IntelligentPersonalAssistant()
    assistant.demo()
 

Example Usage

python intelligent_personal_assistant.py

python intelligent_personal_assistant.py

Explanation

Key Features

• Voice Recognition: Listens and processes voice commands.
• Task Management: Manages tasks and reminders.
• Error Handling: Validates inputs and manages exceptions.
• CLI Interface: Interactive command-line usage.

Code Breakdown

1. Import Libraries and Setup Assistant

import speech_recognition as sr
import pyttsx3
import schedule
import time

import speech_recognition as sr
import pyttsx3
import schedule
import time

2. Voice Recognition and Task Management Functions

def listen_command():
    r = sr.Recognizer()
    with sr.Microphone() as source:
        print("Listening...")
        audio = r.listen(source)
    try:
        command = r.recognize_google(audio)
        return command
    except Exception as e:
        print(f"Error: {e}")
        return ""
 
def speak(text):
    engine = pyttsx3.init()
    engine.say(text)
    engine.runAndWait()
 
def add_task(task):
    print(f"Task added: {task}")

def listen_command():
    r = sr.Recognizer()
    with sr.Microphone() as source:
        print("Listening...")
        audio = r.listen(source)
    try:
        command = r.recognize_google(audio)
        return command
    except Exception as e:
        print(f"Error: {e}")
        return ""
 
def speak(text):
    engine = pyttsx3.init()
    engine.say(text)
    engine.runAndWait()
 
def add_task(task):
    print(f"Task added: {task}")

3. CLI Interface and Error Handling

def main():
    print("Intelligent Personal Assistant")
    while True:
        cmd = input('> ')
        if cmd == 'listen':
            command = listen_command()
            speak(f"You said: {command}")
        elif cmd == 'add':
            task = input("Task: ")
            add_task(task)
        elif cmd == 'exit':
            break
        else:
            print("Unknown command. Type 'listen', 'add', or 'exit'.")
 
if __name__ == "__main__":
    main()

def main():
    print("Intelligent Personal Assistant")
    while True:
        cmd = input('> ')
        if cmd == 'listen':
            command = listen_command()
            speak(f"You said: {command}")
        elif cmd == 'add':
            task = input("Task: ")
            add_task(task)
        elif cmd == 'exit':
            break
        else:
            print("Unknown command. Type 'listen', 'add', or 'exit'.")
 
if __name__ == "__main__":
    main()
