![]() There are two categories of magic: line magics and cell magics. We will start with a few basics before moving on to more interesting cases. There exist far more magics than it would make sense to cover here, but it’s worth highlighting a variety of examples. Although they often resemble unix commands, under the hood they are all implemented in Python. Magics are handy commands built into the IPython kernel that make it easier to perform particular tasks. However, IPython magics offer a solution. Note that the shell in which ! commands are executed is discarded after execution completes, so commands like cd will have no effect. It is also possible to use Python variables in your shell commands by prepending a $ symbol consistent with bash style variable names. As a simple illustration: !echo Hello World!! This can be useful when dealing with datasets or other files, and managing your Python packages. ![]() Any line in a code cell that you begin with an exclamation mark will be executed as a shell command. Now we’re ready to become Jupyter wizards! Shell CommandsĮvery user will benefit at least from time-to-time from the ability to interact directly with the operating system from within their notebook. Fortunately, awesome alternatives are already cropping up on GitHub. If you’re a JupyterLab fan, you’ll be pleased to hear that 99% of this is still applicable and the only difference is that some Jupyter Notebook extensions aren’t compatible with JuputerLab.
