使用tkinter，用直方图动画表示排序过程的python代码

一，冒泡排序

代码：

from tkinter import *import timeimport randomlistLength = 50height = 600width = 800class BubbleSort():    def __init__(self, mywin):        self.win = mywin        self.list = [x for x in range(1, listLength+1)]        self.barwidth = (width-20)//listLength        self.height = (height-30)//listLength        self.left= (width-listLength*self.barwidth)//2        self.reset()    def reset(self):        random.shuffle(self.list)        self.drawRect(-1,50)    def drawRect(self,move,flag):        self.win.canvas.delete("line")        for i in range(len(self.list)):            color = "white"            if i == move:                color = "RED"            if i > flag:                color = "BLUE"            self.win.canvas.create_rectangle(i * self.barwidth+self.left, height-10,                                  (i+1) * self.barwidth+self.left,                                  height-10-self.height * self.list[i],                                  fill=color, tag="line")            self.win.canvas.create_text(i * self.barwidth+self.left+self.barwidth/2,                                  height-18-self.height * self.list[i],                                  text=str(self.list[i]), tag="line")        self.win.canvas.after(100)        self.win.canvas.update()    def sort(self):        for i in range(0,len(self.list)-1):            for j in range(0,len(self.list)-i-1):                if self.list[j] > self.list[j+1]:                    temp = self.list[j]                    self.list[j] = self.list[j+1]                    self.list[j+1] = temp                    self.drawRect(j+1,len(self.list)-i-1)class SortWin():    def __init__(self):        self.win = Tk()        self.win.title("Bubble Sort")  # Set a title        self.canvas = Canvas(self.win, bg="white", width=width, height=height)        self.canvas.pack()        self.frame = Frame(self.win)        self.frame.pack()        self.label = Label(self.frame, text="冒泡排序法")        self.label.pack(side=LEFT)        self.btStep1 = Button(self.frame, text="Begin", command=self.begin)        self.btStep1.pack(side=LEFT)        self.btStep2 = Button(self.frame, text="Reset", command=self.reset)        self.btStep2.pack(side=LEFT)    def begin(self):        self.bubbleSort.sort()    def reset(self):        self.bubbleSort.reset()    def show(self):        self.bubbleSort = BubbleSort(self)        self.win.mainloop()main = SortWin()main.show()
