Kaggle Notebook Rules

Kaggle Notebook Format Rules

Cell Separators

• Code cells: # %% [code]
• Markdown cells: # %% [markdown]

Markdown Cell Formatting

CRITICAL RULES:

1. Every line must start with # (hash + space)
2. NEVER use triple quotes (""" or ''') for markdown cells
3. NO empty lines with only # - they create extra whitespace in rendered notebook

Correct markdown cell:

# %% [markdown]
# # Title
# Content line 1
# Content line 2
# - Bullet point 1
# - Bullet point 2

Code Cell Conventions

• Printed output in English
• File extension: .py (not .ipynb)
• Dataset paths: /kaggle/input/dataset-name/

Package Installation

• Only install packages NOT pre-installed on Kaggle
• Use %pip install -q package-name (not !pip install)
• Common libraries (pandas, numpy, scipy, scikit-learn, torch, torchvision) are already available

Common Mistakes to Avoid

1. Triple quotes in markdown cells → Use # prefix on every line
2. Empty # lines → Remove them
3. Missing # prefix → Every line must start with #
4. Using ## Title → Use # Title only
5. Using !pip → Use %pip
