Python – Programs on Relational Operators

Relational operators:

• Operators are > , < , >= , <= , == , !=
• These operators validate the relation among operands and return a boolean value.
• If relation is valid returns True else False

Program to understand Relational operators:

print(“Relational operations”) print(“5>3 :”, 5>3) print(“5==3 :”, 5==3) print(“5<3 :”, 5<3) print(“5!=3 :”, 5!=3) print(“5>=3 :”, 5>=3) print(“5<=3 :”, 5<=3)

If-else Conditional Statement:

Check the Number is Zero or Not

n = int(input(“Enter number : “)) if(n==0):     print(“Number equals to zero”) else:     print(“Number is not zero”)

Check the Number is Positive or Not

n = int(input(“Enter number : “)) if(n>=0):     print(“Positive Number”) else:     print(“Negative Number”)

Check the 2 numbers equal or not

n1 = int(input(“Enter First num : “)) n2 = int(input(“Enter Second num : “)) if(n1==n2):     print(“Equal numbers”) else:     print(“Not equal Numbers”)

Check the first number greater than second number or not

n1 = int(input(“Enter First num : “)) n2 = int(input(“Enter Second num : “)) if(n1>n2):     print(“First Number is big”) else:     print(“Second Number is big”)

Check the person eligible for vote or not

age = int(input(“Enter age : “)) if(age>=18):     print(“Eligible for vote”) else:     print(“Not eligible for vote”)

Check the number is divisible by 7 or not

num = int(input(“Enter number : “)) if(num%7==0):     print(“Divisible by 7”) else:     print(“Not divisible by 7”)

Check the number is even or not

num = int(input(“Enter number : “)) if(num%2==0):     print(“Even Number”) else:     print(“Not Even”)

Check the last digit of number is zero or not

num = int(input(“Enter number : “)) if(num%10==0):     print(“Last digit is zero”) else:     print(“Last digit is not zero”)

Check the sum of 2 numbers equal to 10 or not

n1 = int(input(“Enter First number : “)) n2 = int(input(“Enter Second number : “)) if(n1+n2==10):     print(“Equal to 10”) else:     print(“Not equal to 10”)

Check last digits of given 2 numbers equal or not

n1 = int(input(“Enter First number : “)) n2 = int(input(“Enter Second number : “)) if(n1%10 == n2%10):     print(“Equal”) else:     print(“Not equal”)

Check the average of 3 numbers greater than 60 or not

print(“Enter 3 numbers :”) n1 = int(input()) n2 = int(input()) n3 = int(input())   if((n1+n2+n3)/3 > 60):     print(“avg Greater than 60”) else:     print(“Not”)

Check the last digit of number is divisible by 3 or not

n = int(input(“Enter num : “)) if((n%10)%3==0):     print(“Last digit divisible by 3”) else:     print(“Not divisible”)
