The easiest way to reverse a list in Python isusing slicing([::-1]), which creates a new reversed list without modifying the original: numbers=[1,2,3,4,5]reversed_numbers=numbers[::-1]print(reversed_numbers)# Output: [5, 4, 3, 2, 1] ...
There are 3 ways to reverse a list in Python. Using the reversed() built-in function Using the reverse() built-in function Using the list slicing Method 1 – Using thereversed()built-in function reversed()is a built-in function in Python. In this method, we neither modify the original...
1. Using list slicing The easiest and simplest approach for traversing a Python list is that - You can use list slicing. Use negative indexing i.e.,::-1. The statementlist[::-1]will return the list in reverse order. Example # Traverse a Python list in reverse order# Using list slicin...
Python also provides a slicing operator that can be used to reverse a list. The slicing operator[::-1]returns a new list that is a reversed copy of the original list. Here’s an example: # List of planetsplanets = ['Mercury','Venus','Earth','Mars']print('Original List:', planets)...
for i in reversed(l): print(i) Output: As we discussed earlier, reversing a list is not only done by using functions reverse() and reversed(), but also we can use slicing for reversing the given list. In Python, slicing is used for reversing the list, which this works as to whereas...
9. Is there an alternative way to reverse a list in Python list method?Yes, a list can be reversed using slicing with the [::-1] syntax or the reversed() function for creating an iterator.10. What is the time complexity of the Python reverse() method?
# Reverse an array using list slicing # Initialize the array arr = [1, 3, 6, 9, 12] print("Given array is:", arr) rev_arr = arr[::-1] print( "After reversing an array:", rev_arr) Yields the below output. 1.2 Reverse an Array using the For Loop in Python ...
1. Using List Slicing to Reverse an Array in Python We can reverse a list array using slicing methods. In this way, we actually create a new list in the reverse order as that of the original one. Let us see how: #The original array arr = [11, 22, 33, 44, 55] print("Array is...
2. Using sorted() to Order List in Reverse Thesorted() functionwithreverse=Truein Python is used to sort a sequence (such as a list, tuple) in reverse order. The function returns a new sorted list, leaving the original sequence unchanged. ...
2. Using extended slicing The[::-1]slice makes a copy of the list in reverse order, which can be used in the for-loop to print items in reverse order. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 if__name__=='__main__': ...
