As long as you follow the simple rules of variable naming, and avoid reserved words, you have a lot of choice when you name your variables. In the beginning, this choice can be confusing both when you read a program and when you write your own programs. For example, the following three programs are 4.13. WRITE CODE QUESTIONS 2. . Activity: 4.13.6 ActiveCode (cndtnl-wc-pay2q) Question. Answer. Write the code to calculate and print the cost of a 14 mile cab ride. If the distance traveled is less than or equal to 12 miles the cost is $2.00 a mile, and if the distance traveled is more than 12 miles the cost is $1.50 a mile. Assign the final cost to the variable total. 5.14. MULTIPLE CHOICE QUESTIONS a, b; It will print the value of a and b.-3, b; It will print -3 and the value of b. a, 5; It will print the value of a and 5.-3, 5; It looks like it will print this, but it will actually print the values with a space between them. 9.3. TRAVERSING A LIST The most common way to traverse the elements of a list is with a for loop. The syntax is the same as for strings: Activity: 9.3.1 Using a for loop to traverse a list. (listCheese) This works well if you only need to read the elements of the list. But if you want to write or update the elements, you need the indices.

7.2. TRAVERSING ARRAYS WITH FOR LOOPS 7.2.2. For Loop to Traverse Arrays¶. We can use iteration with a for loop to visit each element of an array. This is called traversing the array. Just start the index at 0 and loop while the index is less than the length of the array. Note that the variable i (short for index) is often used in loops as the loop counter variable and is used here to access each element of an array with its index. 9.3. TRAVERSING A LIST The most common way to traverse the elements of a list is with a for loop. The syntax is the same as for strings: Activity: 9.3.1 Using a for loop to traverse a list. (listCheese) This works well if you only need to read the elements of the list. But if you want to write or update the elements, you need the indices. 7.3. PRECEDENCE OF OPERATORS 7.3. Precedence of Operators ¶. We have now added a number of additional operators to those we learned in the previous chapters. It is important to understand how these operators relate to the others with respect to operator precedence. Python will always evaluate the arithmetic operators first (** is highest, then multiplication/division 6.5. MUTATOR METHODS 6.5. Mutator Methods¶. Corresponding to each get method, programmers also provide a public set method to change the value of a private instance variable in a class. These are called mutator methods (or settters or set or modifier methods). They are void methods meaning that they do not return a value, but they do take a parameter, the new value for the instance variable. 7.14. MULTIPLE CHOICE QUESTIONS 7.14. Multiple Choice Questions — Python for Everybody - Interactive. 7.14. Multiple Choice Questions ¶. csp-11-1-1: What is printed by the following statements?

Tkinter has four basic ways to group widgets. These are described in the following table. They are often referred to as “container” widgets because in the widget hierarchy of a GUI program they are the 9.16. LOOPING AND COUNTING Activity: 9.16.1 ActiveCode (chp08_fun2) The function count takes a string as its parameter. The for statement iterates through each character in the string and checks to see if the character is equal to the value of aChar. If so, the counting variable, lettercount, is incremented by one. When all characters have been processed, the

lettercount

5.25. FUNCTIONS AND LISTS WRITE CODE QUESTIONS Create a function called remove_indices_after_first_max_value that takes in a parameter num_list and returns a new_num_list with values up to the max value of the list. 5.18. FUNCTIONS WRITE CODE QUESTIONS Fix the 5 errors in following code for the function remainder so that it takes in two numbers as parameters (x and y), where x is required but y is optional and defaults to 4. The function should return the remainder of x divided by y. 5.23. FUNCTIONS AND CONDITIONALS MIXED-UP CODE QUESTIONS Create a function called get_letter_grade that takes in a parameter percentage and returns a string variable called letter_grade. If the percentage is greater than 100, return “You can’t get over

100.”.

5.21. FUNCTION AND STRING MIXED-UP CODE QUESTIONS Reorder the given code to create a function perimeterRectange, that takes two variable x and y and prints the perimeter of the rectangle in the form - “The perimeter of the given rectangle with height 10

and width 5

2.12. CHOOSING MNEMONIC VARIABLE NAMES 2.12. Choosing mnemonic variable names ¶. As long as you follow the simple rules of variable naming, and avoid reserved words, you have a lot of choice when you name your variables. In the beginning, this choice can be confusing both when you read a program and when you write your own programs. For example, the following three programs are 3.5. USING A STACK IN C++ 3.5. Using a Stack in C++ ¶. Now that we have clearly defined the stack as an abstract data type we will turn our attention to using a stack with the help of the Standard Template Library (STL) in C++. Recall that when we give an abstract data type a physical implementation we refer to 8.9. EASY MULTIPLE CHOICE QUESTIONS 8.9. Easy Multiple Choice Questions — AP CSA Java Review - Obsolete. This book is now obsolete Please use CSAwesome instead. 8.9. Easy Multiple Choice Questions ¶. These problems are easier than most of those that you will usually see on the AP CS A exam.

A shortcut way to get to this course is to type in the url: course.csawesome.org This course is adapted from the Runestone Java Review course to follow the 2019 College Board unit ordering and learning objectives. 7.10. CODE PRACTICE WITH ARRAYLISTS Activity: 7.10.15 ActiveCode (ch8Ex8q) Remove the first element of list and save it to a new variable of type Integer. Because of the nature of remove, everything else in the ArrayList will shift left accordingly. The only thing left to do after that is add this value to the back of the ArrayList.

15.9. HIDDEN WORD

The HiddenWord class will be used to represent the hidden word in the game. The hidden word is passed to the constructor. The class contains a method, getHint that takes a guess and produces a hint. For example, suppose the variable puzzle is declared as follows. RUNESTONE INTERACTIVELOGINTAKE A TOURPYTHONREGISTERAP CSA JAVA

1.4. EXECUTING PYTHON IN THIS BOOK The examples in this book use a mixture of the standard Python interpreter, source code, activecode, and codelens. You will be able to tell which is which by looking for either the Python prompt in the case of a shell mode program, the run button for the activecode, or the forward/backward buttons for codelens.. Check your understanding 9.3. TRAVERSING A LIST The most common way to traverse the elements of a list is with a for loop. The syntax is the same as for strings: Activity: 9.3.1 Using a for loop to traverse a list. (listCheese) This works well if you only need to read the elements of the list. But if you want to write or update the elements, you need the indices. C++ FOR PYTHON PROGRAMMERS Many thanks also to Berea College’s Labor Program for making it possible for students to undergraduate students to receive funding to contribute. Some sections of this book were originally written by Dr. Brad Miller as Java for Python Programmers. These were translated to the C++ language by Dr. Jan Pearce and a team of excellent students 15.16. WIDGET GROUPINGS 15.16. Widget Groupings ¶.

9.12. TRAVERSAL AND THE WHILE LOOP 9.12. Traversal and the while Loop¶. The while loop can also control the generation of the index values. Remember that the programmer is responsible for setting up the initial condition, making sure that the condition is correct, and making sure that something changes inside the body to guarantee that the condition will eventually fail. 5.18. FUNCTIONS WRITE CODE QUESTIONS Fix the 5 errors in following code for the function remainder so that it takes in two numbers as parameters (x and y), where x is required but y is optional and defaults to 4. The function should return the remainder of x divided by y. 5.23.

This project is Open Source, but it does take time and resources. Especially as our popularity has grown we have server costs. We were also able to make great progress during the Summer of 2013 thanks to a generous grant from ACM-SIGCSE that supported one of our undergraduate students. It would be great if we could have a student working on this

all the time.
