How can I create and use custom magic commands in Jupyter?

You can create custom magic commands in Jupyter by defining a function and using the @magics_class decorator from the IPython library.

Can you show me a simple example of a custom magic command?

Sure! Here's a basic example:

from IPython.core.magic import register_line_magic

@register_line_magic
def mymagic(line):
    print(f'You entered: {line}')

You can then use %mymagic your_input in a Jupyter cell.

What if I want to create a cell magic command instead?

For cell magic, you can use the @register_cell_magic decorator. Here's an example:

from IPython.core.magic import register_cell_magic

@register_cell_magic
def mycellmagic(line, cell):
    print(f'Line: {line}')
    print(f'Cell content:
{cell}')

You can use it with %%mycellmagic at the start of a cell.

Are there any limitations to custom magic commands?

Yes, custom magic commands can only be used within Jupyter notebooks and may have limitations based on the IPython environment.
