You should use .items() to access key-value pairs when iterating through a Python dictionary. The fastest way to access both keys and values when you iterate over a dictionary in Python is to use .items() with tuple unpacking.To get the most out of this tutorial, you should have a ba...
The following example demonstrates how to add to an array using theappend(),extend(), andinsert()methods: importarray# create array objects, of type integerarr1=array.array('i',[1,2,3])arr2=array.array('i',[4,5,6])# print the arraysprint("arr1 is:",arr1)print("arr2 is:",a...
In this tutorial, I will explain how toconcatenate tuples in Python. As a data scientist working on a project for a US-based company, I recently encountered a situation where I needed to combine multiple tuples into a single tuple. After researching and experimenting with various methods, I ...
In this tutorial, you’ll learn how to sort various types of data in different data structures, customize the order, and work with two different ways of sorting in Python. You’ll need a basic understanding of lists and tuples as well as sets. These are the data structures you’ll be ...
Another way to compare tuples in Python is to use the built-in all() function. The all() function takes an iterable (like a tuple) as input and returns True if all elements in the iterable evaluate to True, and False otherwise. To compare two tuples using all(), we can convert ...
3. What is list() in Python? The list() function is a built-in Python function that converts an iterable (like a string, tuple, or set) into a list. This is particularly useful when you need to manipulate individual elements of an iterable or when you want to convert a string into...

Q #3) How do we add elements into an array in Python? Answer: Elements can be added into an array in many ways. The most common way is using the insert(index, element) method, where index indicates the position where we will like to insert and element is the item to insert. However...
insert(0, item) inverted_tuple = tuple(inverted_list) print("Original tuple=",original_tuple) print("Inverted tuple=",inverted_tuple) Output Original tuple= (1, 2, 3, 4, 5) Inverted tuple= (5, 4, 3, 2, 1) Method 4: Using Extended Unpacking Python's capability to allow us to...
Create List of Tuples Tuples are used to store multiple items in one variable, and they are immutable, meaning they can’t be changed. To create the list of tuples that we will use in this tutorial, run the line of code below in yourPython IDE: ...
