Python matplotlib example: inline helper

"""Helper module that reassigns `matplotlib.pyplot.ioff` to use
in Jupyter/Ipython notebooks and assigns `matplotlib.pyplot.inline`
to use inline mode in notebooks. It allows notebooks to be exported
to scripts easily, as it doesn't use magic.

In notebooks:
import matplotlib.pyplot as plt
import inline_helper

#Turn inline on, this is interactive
#Equivalent to %matplotlib inline
plt.inline()

# Turn inline off and interactive off
# Equivalent to:
# %matplotlib
# plt.ioff()  #original function
plt.ioff()

#Turn interactive on
plt.ion()
"""
