🚀 How It Works

User enters a YouTube video URL

User selects a format: MP4 video or MP3 audio

The program fetches available streams using pytube

Selected format is downloaded and saved locally

✅ Improved Python YouTube Downloader Code (MP3 + MP4) from pytubefix import YouTube

Ask user for a YouTube video URL

url = input("Enter the YouTube video link: ").strip()

try: yt = YouTube(url)

# Ask user for download type
choice = input("Enter download type (mp3/mp4): ").strip().lower()

if choice == "mp3":
    audio_stream = yt.streams.filter(only_audio=True).first()
    output_file = audio_stream.download()
    print("\n✅ MP3 Download Complete!")
    print("Saved as:", output_file)

elif choice == "mp4":
    video_stream = yt.streams.get_highest_resolution()
    output_file = video_stream.download()
    print("\n🎥 MP4 Download Complete!")
    print("Saved as:", output_file)

else:
    print("\n❌ Invalid choice! Please enter 'mp3' or 'mp4'.")

except Exception as e: print("\n⚠️ Error occurred:", e)

⭐ Improvements Made

Here’s what I improved in your script:

✔ Dynamic URL input

Let user paste any YouTube link instead of a fixed one.

✔ Better variable naming

yt, audio_stream, video_stream, etc. for clarity.

✔ Clean console messages

Added emojis & clear status messages.

✔ Error handling

Wraps everything in a try-except block to avoid program crashing.
