Scipy:

We have the min and max temperatures in a city In India for each months of the year. We would like to find a function to describe this and show it graphically, the dataset given below.

Task is

1. fitting it to the periodic function

2. plot the fit

Data

Max = 39, 41, 43, 47, 49, 51, 45, 38, 37, 29, 27, 25

Min = 21, 23, 27, 28, 32, 35, 31, 28, 21, 19, 17, 18

Solution:Max = 39, 41, 43, 47, 49, 51, 45, 38, 37, 29, 27, 25

Min = 21, 23, 27, 28, 32, 35, 31, 28, 21, 19, 17, 18

months = np.arange(12)

from scipy import optimize

def func(times, avg, ampl, time_offset):

return (avg

+ ampl * np.cos((times + time_offset) * 2 * np.pi / times.max()))

res_max, cov_max = optimize.curve_fit(func, months,

Max, [20, 10, 0])

res_min, cov_min = optimize.curve_fit(func, months,

Min, [-40, 20, 0])

days = np.linspace(0, 12, num=365)

plt.figure()

plt.plot(months,Max, 'ro')

plt.plot(days, func(days, *res_max), 'r-')

plt.plot(months, Min, 'bo')

plt.plot(days, func(days, *res_min), 'b-')

plt.xlabel('Months')

plt.ylabel('Temperature')

plt.show()

My question is shall u explain the solution code??
