TypeError: Food.init() missing 1 required positional argument: 'snake_segments'

Checklist

• snake_game_py/food.py

Add the snake_segments argument to the __init__ method of the Food class and update the generate method to use it.

	## Implementation approach
	To create a state-of-the-art Snake game using pygame, we'll focus on the following:
	1. **Modularity**: Break down the game into components like the game loop, snake object, food object, and UI elements.
	2. **Performance**: Ensure that the game runs smoothly by optimizing the game loop and reducing unnecessary computations.
	3. **User Experience**: Implement intuitive controls, clear visuals, and responsive feedback.
	4. **Progressive Difficulty**: Introduce algorithms to increase the speed of the snake as the score increases.
	5. **Sound Integration**: Use pygame's mixer module to add sound effects.
	6. **Testing**: Use pytest for unit testing to ensure each component works as expected.

Step 2: 🧐 Snippet Analysis

From looking through the relevant snippets, I decided to make the following modifications:

File Path	Proposed Changes
snake_game_py/food.py	Add the snake_segments argument to the __init__ method of the Food class and update the generate method to use it.

---

Step 3: 📝 Planning

I have created a plan for writing the pull request. I am now working my plan and coding the required changes to address this issue. Here is the planned pull request:

Fix missing argument in Food class constructor
sweep/fix-missing-argument

Description

This PR fixes the issue where the Food class in snake_game_py/food.py was missing a required positional argument snake_segments in its __init__ method.

Summary of Changes

• Added the snake_segments argument to the __init__ method of the Food class.
• Updated the generate method of the Food class to use the snake_segments argument.

---

Step 4: ⌨️ Coding

File	Instructions	Progress
snake_game_py/food.py	Add the snake_segments argument to the __init__ method of the Food class and update the generate method to use it.	✅ Commit 10f7c13
