extensibility - I'm using "protected" instead of "private", because someday I could need to extend my classes, is that bad? -

-

i have noticed pattern in code. choose protected, rather private, default access label "hidden" methods , fields in classes. because hides details class functioning users of class, while still leaving space extension in future. there drawback in coding "policy"?

thank you

generally speaking never make because day might having implement or yadayada (it makes life complicated , miserable imho..). if have method should used within class, make private. if ever have extend inheritance reconsider functions might have accessed bellow. anyway abstract methods superclass anyway have thinking of needed when , where..

a reason why ignore said private methods, if want test internal functions i.e. in unit test. in c# can allow project see protected methods externally can write tests against them.

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,
