READ FILES using Python! (.txt, .json, .csv) 🔍

The video tutorial demonstrates how to read different types of files using Python, specifically focusing on plain text, JSON, and CSV files. Here are the key points covered:

• File Paths: The tutorial explains how to create a file path using either a relative or absolute path. It emphasizes the use of escape sequences for special characters in file paths.
• Reading Plain Text Files:
  • Uses the open function with a mode set to 'R' (read).
  • Wraps the file reading code in a with statement to ensure the file is properly closed after reading.
  • Reads the content of the file using the read method and assigns it to a variable.
  • Demonstrates error handling for file-related exceptions, such as FileNotFoundError and PermissionError, using try and except blocks.
• Reading JSON Files:
  • Introduces the JSON module to handle JSON files.
  • Shows how to load JSON data using the load method and access specific values using keys.
• Reading CSV Files:
  • Introduces the CSV module for reading CSV files.
  • Explains how to read the CSV file line by line using a for loop, and how to access specific columns by their index.
• Error Handling: The tutorial emphasizes the importance of handling exceptions that may occur during file operations to prevent program interruptions.
