Magic commands are of two kinds: line magics, which are prefixed by a single % character and accomplish on a single line of input, and cell magics, which are associated with the double %% prefix and accomplish on assorted lines of input. Magic functions are callable after having to type the antecedent % if set to 1.

Let’s look at some of them that might be useful in common data assay tasks:

• % pastebin

Consider a python script file.py with the afterward content:

• %matplotlib notebook

The %matplotlib inline function is used to render the static matplotlib plots within the Jupyter notebook. Try replacing the inline part with notebook to get zoom-able & resize-able plots, easily. Make sure the action is called before importing the matplotlib library.

• %run

The %run function runs a python script inside a notebook.

• %%latex

The %%latex action renders the cell capacity as LaTeX. It is useful for autograph algebraic formulae and equations in a cell.

• Yellow Alert Box: Warning

Red Alert Box: Danger

A archetypal way of active a python script from the command line is: python hello.py. However, if you add an additional -i while active the same script e.g python -i hello.py it offers more advantages. Let’s see how.

• Firstly, once the end of the affairs is reached, python doesn’t exit the interpreter. As such we can check the values of the variables and the definiteness of the functions authentic in our program.

• Secondly, we can easily invoke a python debugger since we are still in the analyst by:

This will bring us to the position where the barring has occurred and we can then work upon the code.
