The [::-1] syntax in the above code tells Python to slice the entire string and step backward by -1, which effectively reverses the string. Reversing a String Using the reversed() Function Another way to reverse a string in Python is by using the reversed() function. The reversed() fun...
The reversed string(using loops) is : skeegrofskeeG Explanation :In above code, we call a function to reverse a string, which iterates to every element and intelligentlyjoin each character in the beginningso as to obtain the reversed string. Using recursion # Python code to reverse a string...
Thereversed()function in Python is an iterator that yields elements in reverse order without modifying the original list. Because it creates an iterator rather than a new list,reversed()is memory-efficient, making it a good choice when working with large datasets. ...
To reverse a string in python, we can use the slice syntax by passing the step of -1 and leaving beginning and end positions. Here is an example. mystring = "python" reversed_string = mystring [::-1] print(reversed_string) Output: nohtyp Similarly, we can also use the join() fun...
1. NumPy reverse array using np.flip() function Thenp.flip() functionis one of the most straightforward ways NumPy reserve array in Python. It reverses the order of elements in an array along the specified axis. If the axis is not specified, it reverses the array along all axes. ...
You can use the basic slicing method to reverse a NumPy array. Use this syntax[::-1]as the index of the array to reverse it, and will return a new NumPy array object which holds items in a reversed order. Note: Before applying the NumPy function we need to import the numpy module ...
