N/2 list swap (Problem 29) - InfyTQ Solution in Python

N/2 list swap (Problem 29)

InfyTQ Solution in Python

PROBLEM STATEMENT

Given a list of numbers, write a python function to exchange the first n/2 elements of a list with the last n/2 elements. The function should return the new list.

n represents the number of elements in the list. Assume that it will always be even.

Sample Input	Expected Output
[1,2,3,4,5,6,7,8,9,10]	[10,9,8,7,6,1,2,3,4,5]

SOLUTION

#PF-Prac-29 def exchange_list(number_list): #start writing your code here l=len(number_list) firsthalf=number_list[0:l//2] secondhalf=number_list[l//2:] secondhalf.reverse() number_list=[] for i in secondhalf: number_list.append(i) for i in firsthalf: number_list.append(i) return number_list number_list=[1,2,3,4,5,6] print(exchange_list(number_list))
