YouTube Manager - Python Terminal Application

A lightweight Python-based YouTube video manager that allows users to track their favorite videos without requiring a database. This application stores video information in a simple text file using JSON format, making it perfect for beginners learning file handling and basic CRUD operations in Python.

Features

• List Videos: View all saved YouTube videos with their names and durations
• Add Videos: Store new YouTube videos with name and duration
• Update Videos: Modify existing video details
• Delete Videos: Remove videos from your collection
• Persistent Storage: Data is saved between sessions using a text file

Code Explanation

1. Data Storage Functions

def load_data():
  try:
      with open('youtube.txt', 'r') as file:
        return json.load(file)
  except FileNotFoundError:
      return []
    
def save_data_helper(videos):
      with open('youtube.txt', 'w') as file:
        json.dump(videos, file)

• load_data(): Reads video data from 'youtube.txt' using JSON format. If the file doesn't exist, returns an empty list.

• save_data_helper(videos): Writes the current video list to 'youtube.txt' in JSON format.

2. Core Operations

def list_all_videos(videos):
    # Displays all videos with numbering

def add_video(videos):
    # Adds a new video with user-provided name and duration

def update_video(videos):
    # Updates an existing video's details

def delete_video(videos):
    # Removes a video from the collection

Each operation calls save_data_helper(videos) to persist changes to the file.

3. Main Application Loop

  def main():
    videos = load_data()
    while True:
        # Display menu options
        # Process user choice with match-case statement

The main function loads existing data and presents a continuous menu until the user chooses to exit.
