Q. Consider below given function headers. Identify which of these will cause error and why?

(i) def func(a = 1, b):

(ii) def func(a = 1, b, c = 2):

(iii) def func(a = 1, b = 1, c = 2):

(iv) def func (a = 1, b = 1, c = 2, d):

Answer :-

Function headers (i), (ii) and (iv) will cause error because non-default arguments cannot follow default arguments.

Only function header (ii) will not cause any error.
