Python offers the 'in' operator to verify that a value is present in a tuple. This operator is very useful when you are looking for items in a collection without requiring loops or complex logic. In this article, we will discuss the 'in' operator and how it works on tuples in Python. Before moving on, we will first discuss tuples. Tuples in Python are an immutable sequence, and they are created by placing a sequence of values separated by a 'comma', with or without the use of parentheses for data grouping. Tuples can have any number of elements and any ... Read More

Tuples in Python are immutable, which means once we create them, we can not change their items. In this article, we will discuss why tuples are immutable before moving on, and we will understand tuples in detail. Tuples in Python Tuples are a data type that belongs to the sequence data type category. They are similar to lists in Python, but they have the property of being immutable. We can't change the elements of a tuple, but we can perform operations suchas counting the number of elements, accessing elements using an index, retrieving the type of the elements, etc. Tuples ...

Python offers many built-in data structures like lists, tuples, sets, and dictionaries, which are used to store and manage data easily. In this article, we will discuss the difference between a Python tuple and a dictionary. Tuple Tuples are a data type that belongs to the sequence data type category. They are similar to lists in Python, but they are immutable. We can't change the elements of a tuple, but we can execute a variety of actions on them, such as count, index, type, etc. Tuples are created in Python by placing a sequence of values separated by a 'comma', with or ...

In this article we are going to discuss about the difference between Python list and array. As you may know both of these are ways to store a collection of items like a bunch of numbers or words but they are not exactly the same. So understanding how they are different will help you select the right one when you are writing your program. List Lists are one of the four most commonly used data structures provided by Python. A list is a data structure in python that is mutable and has an ordered sequence of elements. Lists also support ... Read More

Python variable is a name that you give to something in your program. It basically helps you keep track of objects, which are things like numbers, words or any other data. When you assign an object to a variable, you can use that name to refer to that object later. The data, on the other hand, is still contained within the object. For example, a is assigned the value 100. Here 'a' is a variable. a = 100 This assignment creates an integer object with the value 100 and assigns the variable a to point to that object. In ...

In this article, we will see the differences between two common ways of adding elements to lists in Python: the append method and the "+" operator.   The append() method is used to add elements to the list by utilizing a mutator() method. The '+' operator is used to create a new list with the capacity for one more element. Behaviour of "+" with Python Lists Python accesses each element of the first list by using the '+' operator. When the '+' symbol is used, a new list with the capacity for one more element is produced. The old ... Read More

Sequence Data Types are used to store data in containers in the Python programming language. The different types of containers used to store the data are List, Tuple, and String. Lists are mutable and can hold data of any type, whereas Strings are immutable and can only store data of the str type. Tuples are immutable data types that can store any sort of value. So let's discuss these data types one by one in the coming section - List The sequential data-type class includes the list data type. The list is the only mutable data type in the sequential ...

Lists are one of the four most commonly used data structures provided by Python. A list is a data structure in Python that is mutable and has an ordered sequence of elements. In Python, a list is like a box in which you can keep many things like numbers, names, or your favorite fruits. Let us say you have a list like this: fruits = ["apple", "banana", "mango"] Here, each fruit has a position in the list. But in Python, we start counting from 0, not 1. So here is the indexing of apple, banana, and mango - ... Read More

We are accustomed to using the * symbol to represent multiplication, but when the operand on the left side of the * is a list, it becomes the repetition operator. The repetition operator makes multiple copies of a list and joins them all together. Lists can be created using the repetition operator, *. For example, Examplenumbers = [0] * 5 print numbersOutputThis will give the output −[0, 0, 0, 0, 0][0] is a list with one element, 0.  The repetition operator makes 5 copies of this list and joins them all together into a single list. Another example using multiple ... Read More

The in operator in Python In Python, the in operator determines whether a given value is a constituent element of a sequence such as a string, array, list, or tuple. When used in a condition, the statement returns a Boolean result of True or False. The statement returns True if the specified value is found within the sequence. When it is not found, we get a False. In Python, a list is an ordered sequence that can hold several object types such as integer, character, or float. In other programming languages, a list is equivalent to an array. Square brackets ... Read More
