Relational Operator

Relational operators works with nearly all DATA TYPES IN PYTHON such as numbers stings, lists, tuples, etc. There are six types of relational operators, that python provides. 

Here in the term RELATIONAL OPERATOR, relation refers to the relationship of value in an expression, thus these operator determines the relationship among different operands

In python programing, there are six relational operators for comparing value. These operators are also called comparison operators.

If the comparison is true, the relational expression results into the Boolean value TRUE otherwise the result comes Boolean value FALSE.

IMPORTANT PRINCIPALS 

Relational operator works on the following principles,

1.For numeric type

1. 4 and 4.0 will be treated as equal because of removing trailing from 4.0, it becomes equal to 4 only.
2. Strings are compared on the basis of lexicographical ordering (ordering of dictionary) i.e., alphabetical order
3. Two lists or tuple are equal if they have same elements in the same order

1. Boolean true is equivalent to / and Boolean false to 0 for comparison purpose.

 

For instance, consider the following relational operations given 

a = 3, b = 13, p = 3.0

c = ‘n’, d = ‘g’, e = ‘N’,

f = ‘god’, g = ‘God’, h =‘god’, j = ‘God’, k = “Godhouse”,

L = [1,2,3], M = [2,4,6], N = [1,2,3]

O =(1,2,3), P = (2,4,6), Q = (1,2,3)

Why Relational Operators in Python?

In this tutorial, we have learnt about Relational Operators in python for cbse class 11 & 12 and its related concepts according to CBSE syllabus.  This topic is very important to start learning python programing language for beginners of class 11th and 12th.This tutorial is also useful for Central Board of secondary education (CBSE) student of class 11^{th and} 12^th  , who opted computer science (Code 083) as an optional subject.
