![]() #PYTHON ELSE IF CODE#If it is true, then the code in code block will be executed. The elif is short for else if and is useful to avoid excessive indentation. When Python sees an if-statement, it will determine if the associated logical expression is true. In this case the x > y is false, then the control goes to the body of else block, so the program will execute the code inside else block. In the above code, the if stat evaluate the expression is true or false. Thus, the else clause ensures that a sequence of statements is executed. At your school, the front gate is locked at night for safety. If all the conditions are False, the body of else is executed. If the condition for if is False, it checks the condition of the next elif block and so on. It allows us to check for multiple expressions. In this task, you will implement a check using the if else structure you learned earlier.You are required to create a program that uses this conditional. Python if.elif.else Statement The elif is short for else if. The else statement is to specify a block of code to be executed, if the condition in the if statement is false. Checking whether a statement is true or false allows the code to make intelligent decisions. If the condition is false then the control goes outside the if block. In this case the x > y is true because x=20 and y=10, then the control goes to the body of if block and print the message "X is bigger". In next line, the if statement evaluate the expression (x>y) is true or false. x is assigned as the value 20 and y is 10. In this program we have two variables x and y. If test expression is evaluated to false (0), statements inside the body of if is skipped. If test expression is evaluated to true (nonzero), statements inside the body of if is executed. If the result is True, then the code block following the expression. In Python, if statement evaluates the test expression inside parenthesis. A Python if else statement takes action irrespective of what the value of the expression is. Python programming language provides following types of decision making statements. Here is how we would implement the code sample using the longer form syntax. If the condition is met, the number 20 gets returned, otherwise the else statement returns 0. The nested ternary checks if the variable stores a value of less than 100. It require that the developer specify one or more conditions to be evaluated or tested by the program, along with a statement or statements to be executed if the condition is determined to be true, and optionally, other statements to be executed if the condition is determined to be false. The role of the nested ternary is very similar to the role of an elif/else statement. Specifically, let’s say that you want to include another discount group the ‘Junior Discount’ group for people who are below the age of 18. Decision making is one of the most important concepts of computer programming. ![]()
