先安装这个包

pip install scipy

运行

import tkinter as tk
from scipy.integrate import quad# 创建主窗口
root = tk.Tk()
root.title("积分计算器")# 定义计算积分的函数
def calculate_integral():# 获取用户输入的函数表达式function = function_entry.get()# 获取积分下限和上限lower_limit = float(lower_limit_entry.get())upper_limit = float(upper_limit_entry.get())# 使用SciPy的quad函数计算积分result, _ = quad(lambda x: eval(function), lower_limit, upper_limit)# 显示积分结果result_label.config(text=f"积分结果: {result}")# 创建GUI元素
function_label = tk.Label(root, text="函数表达式:")
function_label.pack()
function_entry = tk.Entry(root)
function_entry.pack()lower_limit_label = tk.Label(root, text="下限:")
lower_limit_label.pack()
lower_limit_entry = tk.Entry(root)
lower_limit_entry.pack()upper_limit_label = tk.Label(root, text="上限:")
upper_limit_label.pack()
upper_limit_entry = tk.Entry(root)
upper_limit_entry.pack()calculate_button = tk.Button(root, text="计算积分", command=calculate_integral)
calculate_button.pack()result_label = tk.Label(root, text="")
result_label.pack()# 运行主事件循环
root.mainloop()
