When you compare two values, the expression is evaluated and Python returns the Boolean answer: ExampleGet your own Python Server print(10>9) print(10==9) print(10<9) Try it Yourself » When you run a condition in an if statement, Python returnsTrueorFalse: ...
number, object, array, boolean or null. In JavaScript, array values can be all of the above, plus any other valid JavaScript expression, including functions, dates, and undefined. JavaScript Arrays You can create a JavaScript array from a literal: Example myArray = ["Ford", "BMW", "Fiat...
In this example, we have used the boolean indexing to select only the odd numbers from thearray1array. Here, the expressionnumbers % 2 != 0is a boolean mask. If the elements ofarray1meet the condition specified in the boolean mask, it replaces the element (odd numbers) withTrue, and ...
Example 2: Input: expression = "|(f,t)" Output: true Example 3: Input: expression = "&(t,f)" Output: false Example 4: Input: expression = "|(&(t,f,t),!(t))" Output: false Constraints: 1 <= expression.length <= 20000 ...
03:58Let’s now see an example that demonstrates howTrueandFalsebehave whenthey’re integers. If you go ahead and typecastTrueas an integer,you’re going to get1. And then if you do the same thing forFalse,you’re going to get the integer0. So that means, for example,if you were ...
