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...

Loop Statements

Loop STATEMENTS The Loop statements allow a set of instructions to be performed repeatedly until a certain condition is fulfilled. The iteration statements are also called loops or looping statements. THE FOR LOOP The for loop is the easiest to understand of the python loops. Syntax: For I in range(lowerlimit,upperlimit): Loop Body The program will run until I value becomes equal to upperlimit – 1. Example: For I in range(1,5): Print(“Hello”) This program will print Hello 4 times, ie from 1 to 4 (upper limit-1)  I value will start as 1 then loop body will get executed and I value will be incremented. This keeps on taking place until I ==upper limit-1 . After that the program comes out of loop body. THE WHILE LOOP The second loop available in python is the while loop. The while loop is an entry controlled loop. The syntax of a while loop is while (expression): Loop-body Where loop body keep on getting executed until the expression becomes false. When the expression becomes false, th...

Learning Python Basics

                           Python Basics What is VARIABLES in Python? As the name implies the meaning, a variable is something which can be change. A variable is a way of referring to a memory location used by a computer program. A variable is a symbolic name for this physical location. This memory location contains values, like numbers,text or more complicated types. Variables can be treated as a container which can store some value in it. In any other languages for example C++, This is how you write a variable int a = 20 Where int is data type of the variable. Int stands for integer. String refers to text or collection of characters. It is represented in single quotes or double quotes. Float refers to decimal point numbers. In Programming languages like C++ you have to specify the data type of a variable. But in python you don’t have to worry about data type. Whatever value  you give the variable, py...
