Current Date Python code to import the datetime module to access current date output (Note-it will show the current date and time, at the time of execution of code on your machine)…

PYTHON POLYMORPHISM Polymorphism is one of the OOP(object-oriented programming) concepts. Polymorphism in Python is the ability of an object to take many forms. The word “polymorphism” means “many forms”, and in programming, it refers to methods/functions/operators with the same name that can be executed on many objects or classes. Function Polymorphism in Python In Python…

PYTHON MODULE Module is a file or library of codes or set of methods, that can be included in our Application. HOW TO CREATE A MODULE? Creating Module- Module can be created by saving the code in a file with the file extension .py. Python Code- Save below code in file named mymodule.py Using Module-…

PYTHON ITERATORS An Iterator is an object that contains a countable no. of values or elements that can be traversed. An iterator allows a programmer to traverse through all the elements of a collection or iterable objects. An iterator is an object which implements the iterator protocol, which consist of the methods __iter__() and __next__(). WHAT…

PYTHON INHERITANCE Inheritance is a mechanism of object-oriented programming for deriving new classes (sub classes) from existing ones such as super class or base class. It allows us to define a class that inherits all the methods and properties from another class. Parent class or base class, is the class being inherited from. Child class…

PYTHON CONSTRUCTOR- A constructor is a special type of method or function that is used to initialize the instance members of the class. Constructor definition is automatically executed when we create the object of the class. Constructors also verify that there are enough resources for the object to perform any start-up task. The _init_() method simulates…

DEFINITION OF PYTHON CLASS AND OBJECT Python Class The Class is a logical entity that has some attributes and methods, in other words, we can also say that the class is like an object constructor or a “blueprint” for creating objects. Python Objects The Object is an entity that has a state and behavior. HOW…

Syntax of Lambda Functions in Python Examples of Python Lambda Functions Lambda function with single argument Code Output Lambda function with multiple arguments Lambda functions can take any number of arguments Code output

WHAT IS A FUNCTION IN PYTHON? A function is a named sequence of statements or a block of code that only runs when it is called by its name. We can pass data, known as parameters, into a function. On calling a function it will execute the block of code and can return data as…

A For loop is used to execute a set of statements, once for each item in a list, tuple, set, dictionary, string, or any iterable object, etc. As shown in below example it will print each fruit available in the list output The break Statement The break statement is used to stop the loop before…

The while Loop While loop is used to execute a set of statements as long as the provided condition is true, as shown in below example that i will be printed as long as i is less than 5 output The break Statement The break statement is used to stop the loop even if the…

Using the if keyword in the Python Syntax- if <Logical_Condition>: <if_block> When <Logical_Condition> returns True value then the code given in <if_block> will execute as shown in below example- Output Using the Elif keyword in the Python The Elif keyword is used to provide another Logical Condition in case the previously provided condition is not…

LIST DEFINITION- A LIST is basically a data structure consisting of a collection of any datatype ordered, changeable, and indexed elements or items, created by enclosing elements in square brackets or by using List() constructor. List items allow duplicate values and its first item has index [0]. Properties of List items- Ordered– List items have…

SETS DEFINITION- A set is basically a data structure consisting of a collection of any datatype unordered, unique, unchangeable, and unindexed elements, created by enclosing elements in curly braces or a set constructor.Note-Set items are unchangeable, but you can remove and/or add items HOW TO CREATE A SET IN PYTHON? By using curly braces Python…

DICTIONARIES A dictionary is a mapping of keys to values. It’s also sometimes called a hash table or associative array. The keys serve as indices for accessing values. Dictionaries are written with curly brackets as shown in the below examples. Dictionaries in python are used to store data values in key: value pairs each pair…

TUPLE A Tuple is an ordered and unchangeable collection of python objects, each object is separated by a comma and the whole set is enclosed by parenthesis. Tuples allow duplicate values. PROPERTIES OF TUPLE Tuple items or objects are ordered, unchangeable, and allow duplicate values. Tuple items are indexed, the first item has an index [0], the…
