Writing first python program

  We are here to write our first program,it will  be an easy program just printing the entered word or value. The syntax of python language is very simple and easy and you dont have to confuse your mind with any complexity. So here is our first program print ( "Hello my name is abc" ) print command is used to display the output written in brackets with inverted commas. As we have typed the sentence "Hello my name is abc". So this command will simply print this sentence as show above in the picture.  

Conditional Statements

Conditional STATEMENTS Normally, the statements are executed sequentially as written in the program (i.e. Top to bottom). This is known as the normal flow of control. But sometimes the operational flow of control has to be altered depending upon a condition. The statements that allow to do so, are known as selection statements. Most important selection statement that python offers is the If statement. Selection statements are also known as conditional statements or decision statements. THE IF STATEMENT An if statement tests a particular condition; if the condition evaluates to true, a course of action is followed i.e. a statement of a set of statements is executed. If the condition is false the course of action is ignored. The syntax of if statement is as shown below: if (expression) : Statement THE ELIF STATEMENT In some cases the program requires you to write multiple if statements. This results in many condition evaluations thus slowing up the program. So to avoid th...

Using input command in python

Today i will show you that how can you use input command in python language, so we will write a simple program that will ask for any name or value and then print that name or value. So here is our simple program. a= input ( "Enter your name" ) print (a) as you can see we have declared "a" a variable that will ask for input "Enter your name" and then print command will print the variable "a". So anything we will type will be printed. As show in the picture below. But here you have to remember, if you are working with integers for some mathematical work than you have to declare input type as integer because then python will take input type as integer and not as word. As show in the picture below. As you can see the syntax that how can we declaring the input type,,int, we have to write int then in brackets we have to enter the input command, int stands for integer and it will declare our input as integer, we have and in print command we have instruc...
