Q. Create a list L containing first 10 even numbers. Write statements (one statement per task) for the following:

 


 
	 
(a)
 
	 
Change elements from index 4 to 9 to first 5 odd numbers in single statement.
 
	 
 
 
 
	 
(b)
 
	 
Add the replaced even numbers to the end of the list.
 
	 
 
 
 
	 
(c)
 
	 
Remove the middle element of the list. If two elements are at the middle of a list, delete the second one.
 
	 
 
 
 
	 
(d)
 
	 
Sort the list in reverse order.
 
	 
 
 

Answer :-

Let, a = [2, 4, 6, 8, 10, 12, 14, 16, 18, 20]

list, b = a + [10, 12, 14, 16, 18, 20]

 
 
	 
(a)
 
	 
Change elements from index 4 to 9 to first 5 odd numbers in single statement.
 
	 
a [4:10] = [1, 3, 5, 7, 9]
 
 
 
	 
(b)
 
	 
Add the replaced even numbers to the end of the list.
 
	 
b = a + [10, 12, 14, 16, 18, 20]
 
 
 
	 
(c)
 
	 
Remove the middle element of the list. If two elements are at the middle of a list, delete the second one.
 
	 
b.pop(int(len(b)/2))
 
 
 
	 
(d)
 
	 
Sort the list in reverse order.
 
	 
b.sort(reverse = True)
OR
>>> b.sort()
>>> b.reverse()
