#Let us do an exercise to find how to use it

my_name = 'Shaf'
my_age = 25
my_height = 78
my_eyes = 'Blue'
print("My name is %s " % my_name)#remember  to use %s for string
print("My age is %d" % my_age)#remember  to use %d for numeric
print("If I add %d and %d I get %d" % ( my_age, my_height,  my_age + my_height))
print("My name is %r, %r" % (my_name, my_age)) # print my name and my age which are of different datatypes. %r prints no motter what the data type is
