How does restarting the kernel and running all cells help in Jupyter Notebook?

Restarting the kernel and running all cells ensures your notebook runs from a clean state without hidden errors or leftover variables. It confirms your code works from start to finish.

Why should you avoid using absolute file paths in your Jupyter Notebook?

Absolute paths can break when sharing notebooks because they depend on your computer's folder structure. Using relative paths or environment variables makes your notebook portable and easier to share.

What is the purpose of using version control (like Git) with Jupyter Notebooks?

Version control helps you track changes, collaborate with others, and revert to previous versions if needed. It keeps your work safe and organized over time.

What is a good practice for organizing code in Jupyter Notebook?

A Write all code in one long cell

B Keep cells short and focused

C Avoid comments and explanations

D Use absolute file paths everywhere

Short and focused cells improve readability and debugging.

Why add markdown cells in your notebook?

A To store data

B To run code faster

C To explain code and add titles

D To hide errors

Markdown cells help explain your work and make it easier to follow.

What does restarting the kernel and running all cells do?

A Runs only markdown cells

B Deletes your notebook

C Saves the notebook automatically

D Clears memory and runs code fresh

It ensures the notebook runs cleanly without leftover variables.

Which file path type is best for sharing notebooks?

A Relative paths

B Absolute paths

C Random paths

D No paths at all

Relative paths work across different computers and folders.

What is the main benefit of using version control with notebooks?

A Track changes and collaborate

B Make notebooks run faster

C Hide code from others

D Automatically fix errors

Version control helps manage changes and teamwork.

Describe three best practices to make your Jupyter Notebook easy to understand and share.

Think about how to organize code, add notes, and manage files.

Explain why restarting the kernel and running all cells is important before sharing your notebook.

Consider what happens if you run code out of order or with old data.
