The following code shows an example to Reverse List Elements in Python. To begin with, create a list with initial values. Further, you can display list elements using a for loop. After that create a for loop. The len() function finds the total number of elements in the list. Hence, iterate through the loop for all elements in the list. In order to reverse the list, swap the first element with the last one. Likewise, swap the second element with the second last element. Once you reach in the middle of the list exit from the loop. In this manner, the list is reversed.

mylist=[7, 12, 90, 11, 55, 84, 5, 0, 377, 121, 69, 39, 29]
sum=0
print('list elements: ')
for i in range(len(mylist)):
   print(mylist[i])


print('Reversing the list...')
for i in range(len(mylist)):
   t=mylist[i]
   mylist[i]=mylist[len(mylist)-(i+1)]
   mylist[len(mylist)-(i+1)]=t
   x=(len(mylist)-1)/2
   if i==x:
      break
   
print('list elements: ')
for i in range(len(mylist)):
   print(mylist[i])
