  # Python Errors
  - error_type: ImportError
    language: python
    severity: high
    what_happened: Python couldn't find and import a module or attribute.
    why_happened: The module you're trying to import doesn't exist, isn't installed, or the attribute doesn't exist in that module. This commonly happens with typos, missing dependencies, or incorrect import paths.
    how_to_fix:
      - Check that the package is installed: pip list | grep package-name
      - Install the package if missing: pip install package-name
      - Verify the import statement matches the package's documentation
      - Check for typos in the module or attribute name
      - If using a virtual environment, ensure it's activated

  - error_type: ValueError
    language: python
    severity: medium
    what_happened: A function received an argument with the right type but inappropriate value.
    why_happened: The value passed to the function doesn't meet the expected constraints or is outside the valid range.
    how_to_fix:
      - Check the function's documentation for valid input ranges
      - Add validation before passing the value
      - Look at the error message for specific constraints
      - Use try/except to catch invalid inputs
    code_snippets:
      - description: Safe conversion
        code: |
          try:
              num = int(user_input)
          except ValueError:
              print("Please enter a valid number")
        language: python

  - error_type: TypeError
    language: python
    severity: high
    what_happened: An operation was performed on an object of inappropriate type.
    why_happened: Python doesn't support the operation between the types you're using, like adding a string to an integer.
    how_to_fix:
      - Check the types of your variables using type()
      - Convert values to the correct type explicitly
      - Use isinstance() to check types before operations
      - Review the function's expected parameter types
    code_snippets:
      - description: Type conversion
        code: |
          num = int("42")  # Convert string to int
          text = str(42)   # Convert int to string
        language: python

  - error_type: SyntaxError
    language: python
    severity: critical
    what_happened: Python encountered invalid syntax in your code.
    why_happened: The code doesn't follow Python's syntax rules. This could be missing colons, parentheses, quotes, or incorrect indentation.
    how_to_fix:
      - Check the line number mentioned in the error
      - Look for missing or extra parentheses, brackets, or quotes
      - Ensure colon after function/class definitions and control flow
      - Check for incorrect indentation
      - Ensure strings have matching quotes
    code_snippets:
      - description: Common fix
        code: |
          # Wrong: if x > 5 print("big")
          # Correct:
          if x > 5:
              print("big")
        language: python

  - error_type: KeyError
    language: python
    severity: medium
    what_happened: A dictionary key was not found in the dictionary.
    why_happened: You tried to access a dictionary key that doesn't exist.
    how_to_fix:
      - Use dict.get(key) to return None instead of raising an error
      - Use dict.setdefault(key, default) to set a default value
      - Check if key exists first: if key in dict
      - Use try/except to handle the missing key
    code_snippets:
      - description: Safe access
        code: |
          value = my_dict.get("missing_key", "default")
        language: python

  - error_type: IndexError
    language: python
    severity: medium
    what_happened: A sequence subscript was out of range.
    why_happened: You tried to access an index that doesn't exist in the list or tuple.
    how_to_fix:
      - Remember Python uses 0-based indexing
      - Check the length before accessing: len(list)
      - Use negative indices to access from the end
      - Remember last index is len(list) - 1
    code_snippets:
      - description: Safe indexing
        code: |
          if index < len(my_list):
              value = my_list[index]
        language: python

  - error_type: AttributeError
    language: python
    severity: high
    what_happened: An object doesn't have the attribute you're trying to access.
    why_happened: The object type doesn't have the method or attribute you're calling. This often happens with typos or incorrect object types.
    how_to_fix:
      - Check the object's type using type()
      - Verify the attribute name matches the documentation
      - Use hasattr() to check if attribute exists
      - Check if you need to call a method with ()
    code_snippets:
      - description: Safe attribute access
        code: |
          if hasattr(obj, 'attribute'):
              value = obj.attribute
        language: python

  - error_type: FileNotFoundError
    language: python
    severity: high
    what_happened: The file or directory you specified doesn't exist.
    why_happened: You're trying to open a file that doesn't exist at the specified path.
    how_to_fix:
      - Check the file path for typos
      - Use absolute paths to avoid confusion
      - Check if you're in the correct working directory
      - Use os.path.exists() to check before opening
    code_snippets:
      - description: Check file exists
        code: |
          import os
          if os.path.exists("file.txt"):
              with open("file.txt") as f:
                  content = f.read()
        language: python

  # JavaScript Errors
  - error_type: ReferenceError
    language: javascript
    severity: high
    what_happened: A variable or function that doesn't exist was referenced.
    why_happened: You're trying to use something that hasn't been declared or is out of scope.
    how_to_fix:
      - Check for typos in variable/function names
      - Ensure variables are declared before use
