preamble.py

#This is my preamble.py file to set things at the beginning for a Jupyter Notebook.
#
#Include this preamble in Notebook at the begining with "import preamble" for easiness of use and to ensure consistency across all notebooks.

# This line configures matplotlib to show figures embedded in the notebook, 
# instead of opening a new window for each figure. More about that later. 
# If you are using an old version of IPython, try using '%pylab inline' instead.
