好的,这里是一个使用Python和Tkinter实现你要求的GUI程序的示例代码:
``` python
import random
import tkinter as tk
class MathQuiz:
def __init__(self, master):
self.master = master
self.master.geometry("400x400")
self.master.title("加法练习")
# 初始化题目和答案
self.numbers = []
self.answers = []
self.create_questions()
# 创建题目和答案框架
self.question_frame = tk.Frame(self.master)
self.question_frame.pack()
self.answer_frame = tk.Frame(self.master)
self.answer_frame.pack()
# 创建题目和答案控件
self.create_question_widgets()
self.create_answer_widgets()
# 创建更换题目的按钮
self.change_button = tk.Button(self.master, text="更换题目", command=self.change_questions)
self.change_button.pack()
# 创建提交答案的按钮
self.submit_button = tk.Button(self.master, text="提交", command=self.check_answers)
self.submit_button.pack()
def create_questions(self):
for i in range(20):
a = random.randint(1, 10)
b = random.randint(1, 10)
self.numbers.append((a, b))
self.answers.append(a + b)
def create_question_widgets(self):
for i in range(20):
label = tk.Label(self.question_frame, text=f"{self.numbers[i][0]} + {self.numbers[i][1]} = ")
label.grid(row=i // 5, column=i % 5)
def create_answer_widgets(self):
self.answer_entries = []
for i in range(20):
entry = tk.Entry(self.answer_frame)
entry.grid(row=i // 5, column=i % 5)
self.answer_entries.append(entry)
def change_questions(self):
# 重新生成题目和答案
self.numbers = []
self.answers = []
self.create_questions()
# 清空之前的题目和答案控件
for widget in self.question_frame.winfo_children():
widget.destroy()
for widget in self.answer_frame.winfo_children():
widget.destroy()
# 重新创建题目和答案控件
self.create_question_widgets()
self.create_answer_widgets()
def check_answers(self):
result = []
for i in range(20):
answer = self.answer_entries[i].get()
if answer == str(self.answers[i]):
result.append("✓")
else:
result.append("✗")
self.create_result_widgets(result)
def create_result_widgets(self, result):
for widget in self.answer_frame.winfo_children():
widget.destroy()
for i in range(20):
label = tk.Label(self.answer_frame, text=result[i])
label.grid(row=i // 5, column=i % 5)
root = tk.Tk()
app = MathQuiz(root)
root.mainloop()
```
这个程序实现了你要求的基本功能,使用了Python的Tkinter库来实现GUI界面。它首先生成了20道加法练习题,然后在界面上显示出来。用户可以在界面上输入答案,然后点击“提交”按钮进行判题。程序会将用户输入的答案与正确答案进行比较,然后在界面上显示出判题结果。同时,用户还可以点击“更换题目”按钮来更换一批新的练习题。
