Python provides multiple ways to iterate over a string array (or list of strings) in reverse order. Below are the most common and efficient methods:
Using reversed()
The reversed() function creates an iterator that traverses the array in reverse without modifying the original array.
string_array = ["apple", "banana", "cherry"]for item in reversed(string_array):print(item)Copied!✕CopyOutput:
cherrybananaappleCopied!✕CopyUsing Slicing ([::-1])
Slicing with [::-1] creates a new reversed copy of the array, which can then be iterated.
string_array = ["apple", "banana", "cherry"]for item in string_array[::-1]:print(item)Copied!✕CopyOutput:
cherrybananaappleCopied!✕CopyUsing a for Loop with range()
This method gives more control over indices and is useful when you need to access both the index and value.
string_array = ["apple", "banana", "cherry"]for i in range(len(string_array) - 1, -1, -1):print(string_array[i])Copied!✕CopyOutput:
cherrybananaappleCopied!✕CopyBest Practices
