Built-in magic commands
Note
To Jupyter users: Magics are specific to and provided by the IPython kernel. Whether magics are available on a kernel is a decision that is made by the kernel developer on a per-kernel basis. To work properly, Magics must use a syntax element which is not valid in the underlying language. For example, the IPython kernel uses the % syntax element for magics as % is not a valid unary operator in Python. While, the syntax element has meaning in other languages.
Here is the help auto generated from the docstrings of all the available magics function that IPython ships with.
You can create an register your own magics with IPython. You can find many user defined magics on PyPI. Feel free to publish your own and use the Framework :: IPython trove classifier.
