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...
To reverse an array uselist slicing. Slicing is a technique using which you can select a particular portion of an array. In this example,arr[::-1]is used to create a new array with reversed elements which is a copy of the originalarray. The-1step value indicates slicing starts from the...
To reverse an array in Python using NumPy, various methods such as np.flip(), array slicing, and np.ndarray.flatten() can be employed. np.flip() reverses elements along a specified axis, array slicing offers a simple syntax for reversing, while flipud() and fliplr() flip arrays vertically...
Using a concept of array slicing. Using a flipud() method of numpy module. Print array in reverse order Let’s see the example first. Example: 1 2 3 4 Input : [10 20 30 40 50 60] Output : [60 50 40 30 20 10] As we know, Python language has not come up with an array da...

The string slicing can be used to perform this particular task, by using “-1” as the third argument in slicing we can make function perform the slicing from rear end hence proving to be a simple solution. # Python3 code to demonstrate working of ...
In Python 3, strings are stored as an array of 16-bit Unicode bytes, encoded in UTF-8 by default. When implementing your custom string-reversing method, you likely need to access the individual characters in the string. You can use square brackets "[]" to access string characters by ...
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. ...
Python List Reverse Copy There are two ways to copy a list and reverse the order of its elements: Use slicinglist[::-1], or Call thereversed(list)method and convert the result to a list using thelist(...)constructor. Here are both in action: ...
