An operator is used to perform some sort of operation on variables and values. For example- a = 4 b = 7 c = a + b print(c) Output 11 Python has the following type of operators     Arithmetic operators Assignment operators Comparison operators Logical Operators Membership Operators Identity […]

Conditional Statements or decision-making is a practice to allow or disallow the execution of code according to certain conditions. Have a look at this piece of code- num = 4 if num < 10: print(“The number is less than 10”) Output The number is less than 10. But if you

A list in Python is a datatype that is used to store multiple values. A list can be formed by assigning different values inside square brackets and separated by commas. Example mylist = ["India", "France", "Australia", "Nepal"] print(mylist) Output: [“India”, “France”, “Australia”, “Nepal”] Items in list are ordered, indexed, and

Like lists, tuples are also used to store multiple values in a single variable. It is a collection that is ordered and unchangeable. Unlike lists, Tuples are written with round brackets. Example sample_tuple = ("east", "west", "north", "south") print(sample_tuple) Output: (“east”, “west”, “north”, “south”) Tuples are ordered Tuples are ordered,

Just like the lists or tuples, a set in python is also one of the collection types. A set is unordered, unindexed, and unchangeable. It is written using curly braces. Example of a set: cities = {'Delhi', 'Mumbai', 'Hyderabad', 'Bhopal'} print(cities) Output: {‘Delhi’, ‘Mumbai’, ‘Hyderabad’, ‘Bhopal’} Set items are unordered

In Python, a dictionary is a collection type that is used to store data in the form of key-value pairs. A dictionary is ordered, changeable, and does not allow duplicate values. The factor that makes a dictionary different from lists, tuples or sets is that in a dictionary each value

According to Google – “In computer programming, a loop is a sequence of instructions that is continuously repeated until a certain condition is reached.” Now try to understand this. Why Loops are so important? Imagine this: You are asked to print “Hello World” 4 times in Python. You might write:

A function is a block of code that can be written once and used as many times as one wants. Once defined, a function can be used by calling it wherever and whenever required. What is the need for functions? Imagine you need to write a chunk of code to get

A lambda function in Python is an anonymous function that can take any number of arguments but can return only one expression. A lambda function is defined by using the ‘lambda’ keyword. Syntax lambda arguments: expression In the syntax: arguments are any value passed expression is the returned value Example:

Python does not have built-in support for arrays like other programming languages like C, C++ etc. But it has many data types like lists that can be used as arrays. Except for one thing, in a typical array, all elements should be of the same type, but in lists, this
