How to interchange first half of the array with second half of array in python?

Following are the code to this question:

l= []#defining an empty list

n=int(input("Enter total element you want to insert: "))#defining variable to input total element

for i in range(0,n):# defining loop to input value in list

   insert=int(input())#defining variable insert to input value

   l.append(insert) # adding the elemenents into the list

x=n//2#calculating midpoint  

l1 =l[:x]#using slicing to hold first-half value in l1 list

l2 =l[x:]#using slicing to hold second-half value in l2 list

print("Before interchange: ")#print message

print ("list : ",l)#print input list

l3=l2 + l1#add value in l3

print("After interchange: ")#print message

#print(l3)  #print list l3

print (str(l3)[1:-1])#print list l3
