WebWhen analyzing scientific data, fitting models to data allows us to determine the parameters of a physical system (assuming the model is correct). There are a number of routines in Scipy to help with fitting, but we will use the simplest one, curve_fit, which is imported as follows: In [1]: import numpy as np from scipy.optimize import curve_fit.
