The above mentioned logic can be applied through if-else statement. The if-else statement requires
three things:
Evaluation statement: Condition or expression that is being checked.
Execution statement: Operations which will be performed if the condition appears to be true.
Else execution block: Operation which will be performed only if the evaluation statement is false.
ELSE-IF Statement
Suppose you need to compare two numbers a, b and check if a is greater than b or they are equal.
To implement this, you need to check two conditions.
In python, the keyword elif, is used for checking another statement in case the previous statement
is false. In python, elif is short for else-if.
Code:
a=23
b=23
if a>b:
print (“a is greater than b”)
elif a==b:
print (“a is equal to b”)
else:
print (“a is less than b”)
Explanation: In this, you are comparing the values of two variables by using a comparison operator.
n the first statement it chec s i a is greater than i this condition is true then it print a is
greater than b”), and if the condition is false, then “elif” block will execute and checks if a is equal
to b, if it is true, then it prints (“a is equal to b”) and if it is false then it print (“a is less than b”).
Alan Turing, the father of modern computer science was famous for developing
the first modern computer.
