Python has nothing built-in which does that, but there are plenty of 
add-on modules which do those sorts of things.  One popular one is 
statsmodels (http://statsmodels.sourceforge.net/)

Please tell us more about the environment you're working in.  I'm 
guessing from the fact that you're calling plt.plot(), that you've 
already got some add-on modules loaded.  Pandas, maybe?
