1. Tkinter

What is GUI

Graphical User Interface (GUI for short) Also known as graphical user interface) refers to a computer operation user interface displayed graphically. A graphical user interface is an interface display format for human-computer communication that allows users to use input devices such as a mouse to manipulate icons or menu options on the screen to select commands, call files, start programs, or perform other daily tasks. Graphical user interfaces have many advantages over character interfaces that use the keyboard to enter text or character commands to complete routine tasks.

The graphical user interface consists of windows, drop-down menus, dialog boxes and their corresponding control mechanisms. They are standardized in various new applications, that is, the same operations are always completed in the same way. In the graphical user interface, what users see and operate are graphical objects, and computer graphics technology is applied.

GUI programming is similar to "building blocks", placing components (Widgets) into the window. The following is the drawing software in windows, which is a typical GUI program:

Commonly used GUI libraries

1. Tkinter

tkinter (Tk interface) is Python's standard GUI library, supporting cross-platform GUI program development. tkinter is suitable for writing small GUI programs, and is especially suitable for beginners to learn GUI programming. This time we will focus on tkinter.

2. wxPython

wxPython is a popular GUI library, suitable for large-scale application development, with stronger functions than tkinter, and the overall design framework is similar to MFC (Microsoft Foundation Classes).

3. PyQT

Qt is an open source GUI library suitable for the development of large-scale GUI programs. PyQT is the standard Python implementation of the Qt toolkit. We can also use the Qt Desginer interface designer to quickly develop GUI applications.

A simplest Tkinter program should contain at least the following four parts:

##Import the tkinter module
Create the main window, also called the root window (that is, the root window)
Add human-computer interaction controls and write the corresponding event functions
Display the main window through the main loop

2. Final effect

Let’s first take a look at the final effect of this project:

Using Python and Tkinter to implement a garbage classification answering application

After the project is run, the program will randomly select 10 questions from the question bank to test. When you answer correctly or incorrectly, there will be a pop-up window prompt. Each correct answer will get 10 points. When all the questions are answered, You will be prompted that the question has been completed and your final score for this exam will be displayed.

3. Project Process

3.1 Analysis Layout

Since this is just a simple question answering program, the overall page does not need to be too complicated. First, a Label label is needed to display the title of each question, then there are 4 vertical (or horizontal) radio button buttons, and finally a click button for the next question is placed below.

3.2 Create a window

To do any project, you need to create the main window first, also called the root window (that is, the root window).

# 导入本次项目用到的库
import tkinter
from tkinter import *
from tkinter.messagebox import *
import random
 
 
if __name__ == &#39;__main__&#39;:
    root = tkinter.Tk()  # 创建tkinter对象
    root.title(&#39;垃圾分类答题考试&#39;)  # 设置标题
    root.geometry("500x200+500+300")   # 设置页面的位置和长宽
    root.mainloop() # 让窗口一直显示出来

The effect is as follows:

3.3 Build a question bank

This time I am doing a question answering program for garbage classification, so I looked for it online Some questions about garbage classification. Here I directly use lists and tuples to store data. To explain, the first one in the tuple is the question, followed by the ABCD options, and finally the answer options for this question.

# 准备一个题库列表

3.4 Create components

We analyzed the layout of this project earlier. We need 1 Label note, 4 radio buttons, and 1 next question button. Let’s start now They are placed in the main window, 10 questions are randomly selected from the question bank and the first question is displayed.

    f2 = Frame(root)  
    f2.pack()
    # 创建下一题的按钮
    Button(f2, text='下一题').pack(side=LEFT)

The effect is as follows:

Using Python and Tkinter to implement a garbage classification answering application

Now there is no response when you click on the next question, because at this time, only the layout of the page has been implemented, and it has not been implemented yet. The function of judging right from wrong.

3.5 Write event function

The logic of the event is that when you click the next question button, the program determines whether your options for this question are consistent with the answers in the question bank. If they are equal, it passes A pop-up window will be used to remind you that the answer is correct; if they are not equal, a pop-up window will be used to prompt you that the answer is wrong. After the prompt is completed, the next question will be displayed immediately. After each judgment, it is necessary to check whether the question is the last question. If so, stop answering the question and obtain the total score of this test.

# 定义一个判断选项正确性的函数
def main(values):
    # 全局引用num和score变量
    global num 
    global score
 
    # 如果选项和答案相等则答对了
    if s.get() == values[num][5]:
        showinfo("恭喜", "恭喜你答对了！")  # 提示你答对了
        score += 10  # 得分加10分
    # 如果选项和答案不相等则答错了
    else:
        showinfo("遗憾", "遗憾你答错了！")  # 提示你答错了
    num = num + 1  # 记录题号
    # 如果题号已经大于等于题目的总长度则需要进行结束并统计总分数
    if num >= len(values):
        showinfo("结果", f"全部题目做完了！\n您的最终得分为{score}分！")  # 提示题目做完了，总结出你的得分
        root.quit()  # 程序退出
        return
    
    # 显示下一题
    label["text"] = str(num+1) + &#39;.&#39; + values[num][0] # 显示题目
    # 显示4个选项
    r1["text"] = values[num][1]
    r2["text"] = values[num][2]
    r3["text"] = values[num][3]
    r4["text"] = values[num][4]
    s.set(&#39;E&#39;)  # 设置初始值为&#39;E&#39;，初始没选中

At the same time, you also need to add the event function to the next question button

Button(f2, text=&#39;下一题&#39;, command=lambda:main(values)).pack(side=LEFT)

A simple version of the answer program has been implemented here, and the effect is as shown before.

四、总结

本次使用了Python中的tkinter库实现了一个简易的垃圾分类答题程序，其中的题库和各种参数大家可以发挥自己的创意，自行进行修改，基于此源码的基础上创作出你的作品！
