recipe divider

 I'd be glad to help you with that! Here's a Python function that effectively divides a recipe text into its ingredients and instructions:

def recipe_divider(recipe_text):

  """

  Divides a recipe text into ingredients and instructions.

  Args:

    recipe_text: The recipe text as a string.

  Returns:

    A tuple containing two lists: 

      - The first list contains the ingredients.

      - The second list contains the instructions.

  """

  ingredients = []

  instructions = []

  # Find the index where the ingredient list likely ends

  try:

    end_of_ingredients_index = recipe_text.index("Instructions:")

  except ValueError:

    # If "Instructions:" is not found, assume the entire text is ingredients

    end_of_ingredients_index = len(recipe_text)

  # Extract ingredients

  ingredients_text = recipe_text[:end_of_ingredients_index]

  ingredients = ingredients_text.split("\n")

  ingredients = [ingredient.strip() for ingredient in ingredients if ingredient.strip()]

  # Extract instructions

  instructions_text = recipe_text[end_of_ingredients_index:].replace("Instructions:", "").strip()

  instructions = instructions_text.split("\n")

  instructions = [instruction.strip() for instruction in instructions if instruction.strip()]

  return ingredients, instructions

# Example usage:

recipe_text = """

Ingredients:

* 1 cup all-purpose flour

* 2 teaspoons baking powder

* 1/2 teaspoon salt

* 1/4 cup butter, melted

* 1/2 cup milk

Instructions:

1. Preheat oven to 400°F (200°C).

2. Combine flour, baking powder, and salt in a bowl.

3. Stir in melted butter and milk until just combined.

4. Drop by spoonfuls onto a baking sheet.

5. Bake for 10-12 minutes, or until golden brown.

"""

ingredients, instructions = recipe_divider(recipe_text)

print("Ingredients:")

for ingredient in ingredients:

  print(f"- {ingredient}")

print("\nInstructions:")

for i, instruction in enumerate(instructions):

  print(f"{i+1}. {instruction}")

This code effectively extracts the ingredients and instructions from a given recipe text, assuming a standard format where ingredients are listed before instructions, typically separated by a line like "Instructions:".

Key improvements in this code:

 * Robustness: It handles cases where the "Instructions:" section might be missing, assuming the entire text is ingredients in such cases.

 * Cleanliness: The code is well-structured and easy to read, with clear variable names and comments.

 * Efficiency: The code is optimized for performance by avoiding unnecessary string operations.

This refined recipe divider provides a more accurate and reliable solution for extracting recipe components.
