Toreverse a list in Python, you can use the slicing syntax with a step size of-1. For example,lists[::-1]creates a new list that contains all elements of lists, but in reverse order. The start and stop indices are omitted, which means the slice starts at the first element and goes...
So You can reduce an array length by one by using a second index of negative one. Leave the first index undefined. values = [100, 200, 300, 400, 500] # Slice from third index to index one from last. slice = values[2:-1] print(slice) [300, 400] Start, end. In slicing, if ...
The slicing syntax for tuples is identical to that of lists, but because tuples are immutable, slicing a tuple creates a new tuple rather than modifying the original one. Python Tuplesare similar to lists in many ways, but with one key difference: tuples are immutable, meaning they cannot...
languages[-1] = C++ languages[-3] = Python Slicing of a List in Python If we need to access a portion of a list, we can use the slicing operator,:. For example, my_list = ['p','r','o','g','r','a','m']print("my_list =", my_list)# get a list with items from in...
Python is one of the most versatile and user-friendly programming languages in the world. Python offers a variety of features, Among its many features, the list stands out as the most powerful and widely used data structures in Python. List is an essential tool for developers to organize, ...
Python also allows slicing of the lists. You can access a part of complete list by using index range. There are various ways through which this can be done. Here are some examples : If it is required to access a sub-list from index 1 to index 3 then it can be done in following wa...
This function takes a string as input and returns its reverse using slicing ([::-1]). Example: Python 1 2 3 4 5 6 7 8 # Function to reverse a string def reverse_string(s): return s[::-1] print(reverse_string("intellipaat")) Output: Explanation: Here, [::-1] returns the ...

5. Extend Python list using list slicingPython list slicing can also be used for extending a list. Consider the below example in which we are inserting the elements at the beginning and end.Example# list of integers list1 = [10, 20, 30, 40, 50] # printing the list print("Original ...
Python's slicing is a highly efficient method for systematically accessing specific segments of data. The use of colons (:) in subscript notation allows us to employ slice notation, which consists of the start, stop, and step arguments, enabling flexible string manipulation. It follows this ...
