What are Jupyter magic commands and how do I use them?

Jupyter magic commands are special commands in Jupyter notebooks that start with % for line magics and %% for cell magics. They help streamline tasks like timing code execution, running scripts, and more.

Can you give me some examples of line magic commands?

Sure! Some common line magic commands include %time for timing a single execution, %pwd to print the current working directory, and %lsmagic to list all available magic commands.

What about cell magic commands?

Cell magic commands, which start with %% , apply to the entire cell. For example, %%timeit can be used to time the execution of the entire cell, and %%writefile allows you to write the contents of the cell to a file.

How do I create my own custom magic command?

You can create custom magic commands by defining a function and using the @magics_class and @magic decorators from the IPython library. This allows you to extend the functionality of Jupyter.
