Consider a function with following header: def info(object, spacing = 10, collapse = 1):

Q. Consider a function with following header:

def info(object, spacing = 10, collapse = 1):

Here are some function calls given below. Find out which of these are correct and which of these are incorrect stating reasons:

a. info( obj1)
b. info(spacing= 20)
c. info( obj2, 12)
d. info( obj11, object = obj12)
e. info( obj3, collapse = 0)
f. info()
g. info(collapse = 0, obj3)
h. info( spacing= 15, object = obj4)

Answer :-

 

 
	 
(a)
 
	 
Correct
 
	 
obj1 is for positional parameter object; spacing gets its default value of 10 and collapse gets its default value of 1.
 
 
 
	 
(b)
 
	 
Incorrect
 
	 
Required positional argument (object) missing; required arguments cannot be missed.
 
 
 
	 
(c)
 
	 
Correct
 
	 
Required parameter object gets its value as obj2; spacing gets value 12 and for skipped argument collapse, default value 1 is taken.
 
 
 
	 
(d)
 
	 
Incorrect
 
	 
Same parameter object is given multiple values one through positional argument and one through keyword(named) argument.
 
 
 
	 
(e)
 
	 
Correct
 
	 
Required parameter object gets its value as obj3; collapse gets value 0 and for skipped argument spacing, default value 10 is taken.
 
 
 
	 
(f)
 
	 
Incorrect
 
	 
Required parameter object's value cannot be skipped.
 
 
 
	 
(g)
 
	 
Incorrect
 
	 
Positional arguments should be before keyword arguments.
 
 
 
	 
(h)
 
	 
Correct
 
	 
Required argument object gets its value through a keyword argument.
