In this example a is equal to b, so the first condition is not true, but the elif condition is true, so we print to screen that "a and b are equal". It is used to test different conditions and execute code accordingly. so the first condition is not true, also the elif condition is not true, Print "Hello World if a is greater than b. if statements. b, AND if c Next Page An else statement can be combined with an if statement. The conditional if..elif..else statement is used in the Python programming language for decision making. we know that 200 is greater than 33, and so we print to screen that "b is greater than a". Python If-Else - Hackerrank solution.Given an integer, , perform the following conditional actions: If is odd, print Weird If is even and in the inclusive range of to , print Not Weird If is even and in the inclusive range of to , print Weird If is even and greater than , print Not Weird elif: If you have only one statement to execute, you can put it on the same line as the if statement. Python relies on indentation (whitespace at the beginning of a line) to define scope in the code. The … filter_none Lately I like atom + script plugin a lot because of the minimalist appearance, it helps me to focus on the code and has a good UI. This is not how programs in the real world operate. You can also have an else without the Python if Statement. Expressions.
