iterate reverse list python code example

Example 1: python reverse range

my_list = [1, 2, 3]
my_list.reverse()           # my_list is modified
print(my_list)              # '[3, 2, 1]'
my_revert = my_list[::-1]   # my_list stays [3, 2, 1]
print(my_revert)            # '[1, 2, 3]'
# Item by item reverse with range(<start>, <end>, <step>)
for i in range(len(my_list), 0, -1):		# my_list is [3, 2, 1]
    print(my_list[i-1])		# '1' '2' '3'
for i in reversed(range(len(my_list))):
    print(my_list[i])       # '1' '2' '3'

Example 2: how to reverse a list in python using for loop

a = ['a', 'b', '4', '5', 'd'] #reverse the List
for i in reversed(a):
    print(i)

Example 3: iterate backwards through a list python

a = ["foo","bar","baz"]
for i in range(len(a)-1,-1,-1):
  print(a[i])

Example 4: python iterate list reverse

for item in my_list[::-1]:
    print item
