Any standard shell command can be used directly in IPython by prefixing it with the ! character. For example, the ls , pwd , and echo commands can be run as follows: In [1]: !ls
There's more to learn about the ipython shell and Python programming in general. But there's not much point in knowing Python if you can't communicate it to your computer. In this brief lesson, we've learned two ways to do it: Using the ipython shell, and executing code line-by-line; Using the python command-line interpreter
Mar 29, 2021 · Jupyter notebooks take the IPython shell to the next level. First of all, they're browser-based, not terminal-based. To get started, install jupyter. If you're using a virtual environment, install it with pip in the environment: pip install jupyter. To install it system-wide, you can use apt on Debian, Ubuntu, or Raspberry Pi:
