如何用python制作二力平衡模拟器 python项目小发明 【安安教具】-【物理】-【二力平衡】模拟器,第1张

二力平衡指的是，一个物体在两个相反力的作用下保持静止或者匀速运动.

二力平衡模拟器则可以体现这一点：

二力平衡模拟器

用到的库有：

from tkinter import *
import tkinter as tk
import threading,os,time

主函数：

if __name__ == '__main__':#主函数
    root = tk.Tk()
    root.resizable(False, False)
    basedesk(root)
    root.mainloop()
    os._exit(0)

主界面代码：

class basedesk():#底板
    def __init__(self, master):
        self.master = master
        self.master.title("二力平衡模拟器")
        self.master.configure(bg='#B1FFF9')
        self.master.geometry("1000x600")
        mainwindow(self.master)
class mainwindow():#主界面
    def __init__(self, master):
        self.master = master
        self.window = tk.Frame(self.master, bg='#e5ffe5')
        self.window.place(x=0,y=0,width=1000,height=600)
        self.window.showname_label=tk.Label(self.window,text="二力平衡模拟器",fg='#26734d', bg='#ffe5ff',font=("Helvetic",60,"bold"),relief=RAISED).place(x=0, y=10,width=1000, height=150)
        self.window.enter_btn=tk.Button(self.window,text="开始",bg='#ffffe5',fg='#333399',font=("Helvetic", 60, "bold"),command=self.changetofunction).place(x=360, y=300,width=250, height=150)
    def changetofunction(self,):
        self.window.destroy()
        functionwindow(self.master)
