#Program to compare two numbers using if else statement
a = int(input('Enter the first number: '))
b = int(input('Enter the second number: '))
if(a > b):
print('First number is greater than second number')
else:
print('Second number is greater than first number')
On running the above program, we get the following output:
Output
Enter the first number: 12
Enter the second number: 25
Second number is greater than first number
THE if-elif-else STATEMENT
Sometimes, we need to evaluate multiple statements to get a certain result. In such scenarios, we
can use the if-elif-else statements to evaluate multiple scenarios. First, it checks and evaluates the
first condition. If it is true, it will execute the respective statement(s). However, if the condition is
false, it moves to the elif statement and evaluates those conditions. Finally, if none of the conditions
evaluates to true, it executes the else block. The syntax of if-elif-else statement is as follows:
if (conditional expression):
statement(s)
elif (conditional expression):
statement(s)
