Does Python need to know the definition of passed, but unused object? -

-

a, b, c , x classes in different modules. want pass object of class x following way: a->b->c

is necessary inculde class x in b, or can pass class x object without knowing definition? (i don't need use methods or anything, return object)

no, not.

about time have from some_module import some_object when going create instances of some_object, or want catch exceptions some_module. if have instances of some_object being passed in use (read, write, or call various attributes, etc.).

(i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
