In Python, you can iterate over a sequence in reverse order using the
reversed() function. The
reversed() function takes a sequence as an argument and returns an iterator that yields the items of the sequence in reverse order. Here's an example:
my_list = [1, 2, 3, 4, 5]
for item in reversed(my_list):
In this example, the
reversed() function is used to create an iterator that yields the items of the
my_list list in reverse order. The
for loop then iterates over this iterator, printing each item to the console. The output of this code would be:
5 4 3 2 1
Note that the
reversed() function returns an iterator, not a list. If you need the reversed sequence as a list, you can convert the iterator to a list using the
my_list = [1, 2, 3, 4, 5] reversed_list = list(reversed(my_list)) print(reversed_list) # Output: [5, 4, 3, 2, 1]
In this example, the
list() function is used to convert the iterator returned by
reversed() to a list. The resulting list is stored in the
reversed_list variable and printed to the console.
