In Python, it's concise, easy and faster to swap 2 variables compared in other Programming languages: Python: x, y = y, x Other programming languages: temp = x x = y y = temp Actually, we can also use the second method just like the other programming…
1. Variables (1) Three ways to define variables: 1) val refers to define an immutable variable; scala> val x = x: Int = scala> x*x res4: Int = scala> res4 + # use result as a value res6: Int = scala> res4 + res6 res7: Int = scala> x = # x i…
1)Suppose a Scanner object is created as follows: Scanner input = new Scanner(System.in); What method do you use to read an int value? A) input.nextInteger(); B) input.integer(); C) input.nextInt(); D) input.int(); 2)The following code fragment reads…

15.1 User-defined typesWe have used many of Python’s built-in types; now we are going to define a new type. As an example, we will create a type called Point that represents a point in two-dimensional space.In mathematical notation, points are often…
A Complete Tutorial to Learn Data Science with Python from Scratch Introduction It happened few years back. After working on SAS for more than 5 years, I decided to move out of my comfort zone. Being a data scientist, my hunt for other useful tools w…
This article explores Python modules and Python packages, two mechanisms that facilitate modular programming. Modular programming refers to the process of breaking a large, unwieldy programming task into separate, smaller, more manageable subtasks or…
