Assignment

Algorithm代做 | tkinter | 代写Python | assignment – 这是一个Algorithm面向对象设计的practice, 考察python基本语法和Algorithm的理解, 涵盖了Algorithm/tkinter/Python等程序代做方面, 这是值得参考的assignment代写的题目，偏基础的python练习题目

Objectives:

• Learn how to use the advanced data structures (such as: list, tuple, string, and dictionary)
• Learn and practice how to use if-elif-else statements.
• Learn and practice how to use loops.
• Learn and practice how to use functions.
• Appreciate the importance of data validations.
• Provide appropriate documentation and good programming style.

####### random Generate pseudo-random numbers

random.random()

Return the next random floating point number in the range [0.0, 1.0).

Functions for integers

random.randrange(stop)

random.randrange(start, stop[, step])

• Return a randomly selected element from range(start, stop, step).

This is equivalent to choice(range(start, stop, step)), but doesnt

actually build a range object.

• The positional argument pattern matches that of range(). Keyword

arguments should not be used because the function may use them in

unexpected ways.

• Changed in version 3.2: randrange() is more sophisticated about

producing equally distributed values. Formerly it used a style like

int(random()*n) which could produce slightly uneven distributions.

random.randint(a, b)

• Return a random integer N such that a <= N <= b.
• Alias for randrange(a, b+1).

Python 3 – tkinter Button

The Button widget is used to add buttons in a Python application. These

buttons can display text or images that convey the purpose of the

buttons. You can attach a function or a method to a button which is

called automatically when you click the button.

Syntax

Here is the simple syntax to create this widget

w = Button ( master, option = value, … )

Parameters

• master This represents the parent window.
• options Here is the list of most commonly used options for this

widget. These options can be used as key-value pairs separated by

commas.

S.No. Option & Description

######## 4

bg

Normal background color.

######## 5

command

Function or method to be called when the button is

clicked.

######## 6

fg

Normal foreground (text) color.

######## 7

font

Text font to be used for the button’s label.

######## 8

height

Height of the button in text lines (for textual buttons) or

pixels (for images).

######## 10

image

Image to be displayed on the button (instead of text).

######## 11

justify

How to show multiple text lines: LEFT to left-justify each

line; CENTER to center them; or RIGHT to right-justify.

######## 12

padx

Additional padding left and right of the text.

13 pady

######## 14

relief

Relief specifies the type of the border. Some of the

values are SUNKEN, RAISED, GROOVE, and RIDGE.

######## 15

state

Set this option to DISABLED to gray out the button and

make it unresponsive. Has the value ACTIVE when the

mouse is over it. Default is NORMAL.

######## 17

width

Width of the button in letters (if displaying text) or pixels

(if displaying an image).

######## 18

wraplength

If this value is set to a positive number, the text lines will

be wrapped to fit within this length.

Example

Try the following example yourself

!/usr/bin/python

from tkinter import *

from tkinter import messagebox

top = Tk() top.geometry(“100×100”) def helloCallBack(): msg = messagebox.showinfo( “Hello Python”, “Hello World”)

B = Button(top, text = “Hello”, command = helloCallBack) B.place(x = 50 ,y = 50 ) top.mainloop()

Result

When the above code is executed, it produces the following result

Example:

!/usr/bin/python

from tkinter import * import random

from tkinter import messagebox

top = Tk() top.geometry(“100×100”)

def helloCallBack(): msg = messagebox.showinfo( “Hello Python”, “Hello World”)

v1 = random.randrange(1, 10,1)

s1 = str(v1) B = Button(top, text = s1, command = helloCallBack) B.place(x = 50,y = 50)

s2 = random.randrange(1, 10,1) B = Button(top, text = s2, command = helloCallBack) B.place(x = 100,y = 50)

top.mainloop()

Python Programming

Description of the problem:

Write a simple menu-driven program called Game of Cards. Each card has

thirteen different numbers. The thirteen possible numbers are: 1 to 1 3. This game has

two cards.

In this game, the maximum bet amount is $ 200 and the minimum bet amount is

$ 5. The amount of the winning prize is directly proportional to the number of matched

cards after the two cards have been generated for each game.

Rules for this game: Initial cash for this game is specified by player. Maximum bet for each game is $ 200. Minimum bet for each game is $ 5. Two cards are used per game. Player can place his or her bet amount for each game. The winning prize is based on how many matched cards have been found: If one matched cards have been found, then the prize is 2 x. If two matched cards have been found, then the prize is 4 x. If no matched card has been found, then the player loses his or her bet for this game-session.

Example of a menu could look like the following:

Optional: The menu-screen could be graphical, instead of text based screen.

Items to be handed in:

• An Algorithm for this program.
• A printed copy of your program Python source code and a printout of at least one sample run.
• All pages must be stapled together. No loose pages are accepted. The disk (USB memory stick) that you hand-in should contain all the related files in a folder called ####assign 4 o where: #### is the last four digit of your student number.

Game of cards
**************************************

1. Help (display rules for this game)
2. Enter the total amount of money you bring in the casino for gambling
3. Roll the cards and then place your bet here (Max. is $50, Min. is $ 1 )
4. Generate the random numbers for the three cards
5. Display your gambling results:
   • current cash on hand
   • number of winnings
   • total number of games played so far
6. Quit

Grading Scheme:

Note:

• Deduct 5% for each missing feature.
• Deduct 5% for any incorrect file name or folder name.
• Deduct 5% for any loose pages.
• Penalty for late submission of assignments is 5% for the first day, and an additional 10% for each day thereafter.

Your  assignment will be graded according to the following scheme:

Correctness, completeness, and no missing features / 3

General, flexible, and efficient / 2

Documentation, style of code, and sample run / 2

User interface, ingenuity, and overall evaluation / 3

Total: / 10
