reverse List in python code example

Example 1: python how to invert an array

revArray = array[::-1]

Example 2: reverse list python

>>> the_list = [1,2,3]
>>> reversed_list = the_list.reverse()
>>> list(reversed_list)
[3,2,1]

OR

>>> the_list = [1,2,3]
>>> the_list[::-1]
[3,2,1]

Example 3: python reverse list

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):
    print(my_list[i-1])		# '1' '2' '3'
for i in reversed(range(len(my_list))):
    print(my_list[i])       # '1' '2' '3'

Example 4: how to reverse a list in python

mylist
[1, 2, 3, 4, 5]

mylist[::-1]
[5, 4, 3, 2, 1]

Example 5: how to reverse a list in python

my_list = [1, 2, 3, 4, 5]
my_list.reverse()

Example 6: print array in reverse python

>>> lst = [1, 2, 3, 4, 5]
>>> lst[::-1]
[5, 4, 3, 2, 1]
