In addition to the concepts from Quiz 1
and Quiz 2,
You should understand and/or be able to use the following Python concepts:
- definite (for) loop
- indefinite (while) loop
- random library functions: randrange(start, stop), choice(list)
- object oriented programming
- graphics objects
- instance of a graphics object
- data and methods of an object
- animation, sleep
- lists and strings as objects
- list and string methods (e.g., strip(), split(), upper(), append(), index())
- python in (and not in) operator used on lists and strings
You should understand how to make instances of the following graphics
objects and how to use their methods:
- GraphWin: setBackground(), getMouse()
- Point: getX(), getY()
- Line: getP1(), getP2()
- Circle: getCenter(), getRadius()
- Rectangle: getP1(), getP2()
- Graphical objects can also: draw(window), undraw(), move(dx, dy), setFill(color)
- also color_rgb(r,g,b)
- Write a program that asks the user for a positive integer, n, and
then calculates and displays the sum of all numbers from 1 to n.
For example, if the user enters 5, the program calculates 1 + 2 + 3 + 4 + 5
- Write a program that reads in student grades from the user
until the user enters a -1. After reading in the -1, the program
should compute and display the average grade:
Please enter your grades below.
Enter a -1 when you are all done...
grade 1: 98
grade 2: 87
grade 3: 65
grade 4: 95
grade 5: 80
grade 6: -1
The average of those 5 grades is 85.000
- Write a program that asks the user for a number (positive integer, n), and then
asks the user to click the mouse n times, anywhere in a graphics window, each time drawing a small
red circle where the user clicked.
- What would be the TYPE of each of these?
p = Point(100,200) type of p?
c = Circle(p, 5) type of c?
x = c.getRadius() type of x?
c2 = c.clone() type of c2?
L = [c, c2] type of L?
m = L type of m?
y = L.getCenter().getY() type of y?
- Given the assignments for S and L, what is the value and type of
L = ["There are", "many", "like it,", "but this one", "is mine."]
S = "abcdefg"
"a" in L
"ABC" in S
