  • Chapter 2 Core Basics
    Chapter 2 Core Basics In this chapter we introduce some of the basic concepts that are important for understanding what is to follow. We also introduce a few of the fundamental operations that are involved in the vast majority of useful programs. 2.1 Literals and Types Section 1.3 introduced the string literal. A string literal is a collection of characters enclosed in quotes. In general, a literal is code that exactly represents a value. In addition to a string literal, there are numeric literals. There are actually a few different types of numeric values in Python. There are integer values which correspond to whole numbers (i.e., the countable numbers that lack a fractional part). In Python, an integer is known as an int. A number that can have a fractional part is called a float (a float corresponds to a real number). For example, 42 is an int while 3.14 is a float. The presence of the decimal point makes a number a float—it doesn’t matter if the fractional part is zero. For example, the literal 3.0, or even just 3., are also floats1 despite the fact that these numbers have fractional parts of zero.2 There are some important differences between how computers work with ints and floats. For example, ints are stored exactly in the computer while, in general, floats are only stored approximately. This is a consequence of the fact that we are entering numbers as decimal numbers, i.e., numbers in the base 10 counting system, but the computer stores these numbers internally as a finite number of binary (base 2) digits.

  • Unary Operator
    Introduction to Python Operations and Variables 1 Topics 1) Arithmetic Operations 2) Floor Division vs True Division 3) Modulo Operator 4) Operator Precedence 5) String Concatenation 6) Augmented Assignment 2 Arithmetic Operations 3 Mixing Types Any expression that two floats produce a float. x = 17.0 – 10.0 print(x) # 7.0 When an expression’s operands are an int and a float, Python automatically converts the int to a float. x = 17.0 – 10 print(x) # 7.0 y = 17 – 10.0 print(y) # 7.0 4 True Division vs Floor Division The operator / is true division and the operator // returns floor division(round down after true divide). True divide / always gives the answer as a float. print(23 // 7) # 3 print(3 // 9) # 0 print(-4 // 3) # -2 print(6 / 5) # 1.2 print(6 / 3) # 2.0 NOT 2! 5 Remainder with % The % operator computes the remainder after floor division. • 14 % 4 is 2 • 218 % 5 is 3 3 43 4 ) 14 5 ) 218 12 20 2 18 15 3 Applications of % operator: • Obtain last digit of a number: 230857 % 10 is 7 • Obtain last 4 digits: 658236489 % 10000 is 6489 • See whether a number is odd: 7 % 2 is 1, 42 % 2 is 0 6 Modulo Operator The operator % returns the modulus which is the remainder after floor division. print(18 % 5) # 3 print(2 % 9) # 2, if first number is smaller, it's the answer print(125 % 10) # 5 print(0 % 10) # 0 print(10 % 0) # ZeroDivisionError 7 Why floor/modulo division is useful Floor division allows us to extract the integer part of the division while the modulo operator extracts the remainder part of the division.

OuterEnvir.subject := subject Our solution is given below. First we need procedures OuterEnvir.object := object analogous to the procedure used for modeling string scanning. OuterEnvir.s_pos := s_pos In addition to a subject, there’s now an “object”, which is the OuterEnvir.o_pos := o_pos result of string synthesis. There now also are two positions, subject := InnerEnvir.subject one in the subject and one in the object. The global identifiers object := InnerEnvir.object subject, object, s_pos, and o_pos are used for these four s_pos := InnerEnvir.s_pos “state variables” in the procedures that follow. (In a real o_pos := InnerEnvir.o_pos implementation, these would be keywords.) fail The string synthesis control structure is modeled as end expr1 ? expr2 → Eform(Bform(expr1),expr2) Most of the procedures specified in the last issue of the are straightforward. Care must be taken, however, The procedures Bform() and Eform() are very similar Analyst to assure that values assigned to the positions are in range — to Bscan() and Escan() used in the last issue of the Analyst this is done automatically for the keyword &pos, but it must for modeling string scanning.

  • 2.13 Augmented Assignment Operators
    Chapter 2 Elementary Programming 2.1 Introduction • You will learn elementary programming using Java primitive data types and related subjects, such as variables, constants, operators, expressions, and input and output. 2.2 Writing Simple Programs • Writing a program involves designing algorithms and data structures, as well as translating algorithms into programming code. • An Algorithm describes how a problem is solved in terms of the actions to be executed, and it specifies the order in which the actions should be executed. • Computing an area of a circle. The algorithm for this program can be described as follows: 1. Read in the Radius 2. Compute the area using the following formula: Area = radius * radius * ∏ 3. Display the area. • Java provides data types for representing integers, floating-point numbers, characters, and Boolean types. These types are known as primitive data types. • When you code, you translate an algorithm into a programming language understood by the computer. • The outline of the program is: public class ComputeArea { public static void main(String[] args) { double radius; // Declare radius double area; // Declare area // Assign a radius radius = 20; // New value is radius // Compute area area = radius * radius * 3.14159; // Display results System.out.println("The area for the circle of radius " + radius + " is " + area); } } CMPS161 Class Notes (Chap 02) Page 1 / 21 Dr. Kuo-pao Yang • The program needs to declare a symbol called a variable that will represent the radius. Variables are used to store data and computational results in the program. • Use descriptive names rather than x and y. Use radius for radius, and area for area.

Johann Wolfgang von Goethe This chapter is not intended as an introduction to programming in general or to program- ming with Python. A tutorial on the Python programming language can be found in the online supplement to this book; if you’re still learning what variables, loops, and functions are, we recommend you go to our tutorial (see Appendix A) before proceeding with the rest of this chapter. You might also want to have a look at the (official) Python Tutorial at www.python.org. Another introduction to Python, with nice material on visualization, is Ref. [41]. Programming, like most other activities, is something you learn by doing. Thus, you should always try out programming-related material as you read it: there is no royal road to programming. Even if you have solid programming skills but no familiarity with Python, we recommend you work your way through one of the above resources, to famil- iarize yourself with the basic syntax. In what follows, we will take it for granted that you have worked through our tutorial and have modified the different examples to carry out further tasks. This includes solving many of the programming problems we pose there. What this chapter does provide is a quick summary of Python features, with an emphasis on those which the reader is more likely not to have encountered in the past.
