Variables & Comments

 Hello Buddies 😍

             I think you already installed python in your devices. Let's start our topic is variables and comments. It's a simple and easy topic. Already you know the hello world code. Before the topic start we will learn fact. 

What is Syntax in Python? 

            For example English language have its own grammar and Telugu also have  grammar but those two not same. In grammar we follow some set of instruction to build a sentence. In python we have Syntax. We need to follow some instruction to write a code.


Variables In Python

                    Variables is like allocating names to a data and also storing values. like containers, Pen drives etc.,


         Here i created a variable (Container) name called Blog and i store a value is PythonGeeksCommunity. F5 is used to run our code. When i call Blog it will show me a output.



Rules TO Write Variables

         Variables are not start with numbers and special characters. You can write starting with capital, small, and underscore like below example.


   If you observer above code there is a syntax error. It means grammatical errors is there in our code. we need to solve them.

Comments

          Comments are like google calendar remainders. It will remember our events. Like comments is used to understanding code better way and after some moths we opened our code. we forgot which logic applied on code. So if we used comments in our code it well helped defiantly.  

Two types of Comments are there 

1) Single Line Comments ( Denoted By #)

2) Multi line Comments ( Denoted By ''' ''' Or """ """ )





         Hope You Like This Blog. If Any Mistakes or Any Topics I Will Not Cover Please Mentioned In Comment. If You Want Video Lecture Below I Mentioned My Channel Video.

Data Types - 1 (Numeric, & Boolean)

 Hello Buddies 😍                                    Data Types is an important concept in any programming language. Our daily life is connected with data. I will tell you a examples  1) Pics, Video & Documents 2) Stock Market  3) Students Marks Report etc.,  Now let's start our topic data types. In python data is classified into these types. 1) Numeric Type:-             INTEGERS :-      + ∞ to -  ∞ between these numbers are called integers           COMPLEX NUMBER      Complex number is a containing of imaginary values is called Complex Number.           Float Numbers    Decimal numbers are called Float Numbers. Ex: - 2.6,0.3 etc.., BOOLEAN TYPE In this data type we have only two values. They are True or False I will explain remaining...

Python Coding Interview Questions Part 7 video explanation

 Hello Buddies,                     This blog is about python interview questions How to solve with step by step process i will explain. So please read it carefully try to understand coding logic. let's start. Question : Write a code to sum of squares of n natural numbers?                         Before dive in to the code explanation 1st look at what is natural number and what is sum of square n natural number. Natural number is positive integers they start from +1 to +infinity. and it denoted by N = {1,2,3,4,.........}. Sum of squares of n natural numbers are 1^2 +2^2+3^2......... So we need to find sum of n natural number like ex : if we take 4 we need to do 1^2+2^2+3^2+4^2 = 30. So this is sum of squares of n natural numbers. Let's look at code part Code :  First take n input and sm = 0 it store sum value. and for i in range we all know it chec...

Why We Need To Learn Programming?

 Hello!😃 Buddies How Are You. 😍          I will tell you a million-dollar answer to why we need to learn any programming language. Before starting our answer, we must know what is programming language right. Programming is used to interact with our machines, we humans have different languages based on different locations right. Let's assume a situation you and your friend went to China you don't know Chinese but your friend know Chinese very well So he will help to explain everything right. Humans have different languages like that machines have their own language is called Binary language. Is written in 0's and 1's.          I will explain with an example, take a simple word like Hello so here if we want write Hello we need alphabets and we need to arrange a format right. It is easy and we can read that word. now we translate our Hello word into Binary language. After converting it will look like this " 010000010101100011000...
