Assignment Q. 1
Enlist the magic commands for Python.Magic Commands
Magic commands let us perform a bunch of tasks from the jupyter notebook itself which otherwise need to be done in the command prompt/shell.
There are two types of magic commands available with Jupyter Notebook:
1. Line Magic Commands: It applies the command to one line of the Jupyter cell as its name suggests.
2. Cell Magic Commands: It applies the command to the whole cell of the notebook and needs to be kept at the beginning of the cell.Line Magic Commands (Starting with "%")
