IPython / Jupyter

Cell Timers

In your jupyter notebook, you can print the time it takes to execute a cell

%%time

You can also time the exceution many times and print the average time. This is great for measuring code performance as your developing code

%%timeit

Embed IPython in a function

You can embed an IPython in your function or script

from IPython import embed; embed()

def this_function():
    print("welcome to this function. I have an IPython interpreter for you...")
    a = 5
    b = 10
    c = a + b
    from IPython import embed; embed()

This can be useful for debugging your function. When you run a Python script, if your function has the embeded IPython, then it will let you explor the values in that function.

Auto reload imports

Put this at the top of your notebook to automatically reload imports

%load_ext autoreload
%autoreload 2
