Q. Carefully go through the following sample code and identify various parts of functions.

(a)
def sub1(a, b):
    print (b, "-", a, " = ", b - a)

(b)
def cube2(x):
    x*x*x
    return x*x*x-x

(c)
def cube1(x):
    return x*x*x

(d)
def greeting():
    print("Welcome to Python")

Answer :-

(a)

 



 
	 
Function Name
 
	 
sub1
