Question

我对after函数以及它在print(str(type(baseDataList))) print("baseDataList: ") for s in baseDataList[:2]: print(*s #<class 'list'> #baseDataList: #43.646556 -79.470988 5761688733 ... #43.645314 -79.462791 5761688679 ... print(str(type(resultData))) print("resultData: ") print(str(type(resultData))) print("Unique: " + str(len(np.unique(resultData>=0))) #<class 'numpy.ndarray'> #resultData: #[ 0 -1 0 5 5 -1 4 10 10 5 10 10 10 10 -1 10 10 10 10 10 4 4 6 1 2 #5 9 -1 10 10 10 6 10 8 10 10 6 8 10 10 3 9 10 10 10 6 6 4 6 6 #10 5 5 4 6 10 6 5 10 5 10 10 10 6 -1 6 4 4 10 10 10 10 10 10 7 #4 10 -1 -1 10 9 -1 5 3 6 6 6 6 6 6 6 4 6 6 4 6 6 6 6 6 #6 6 6 6 6 8 -1 6 10 10 4 4 10 9 -1 9 10 10 5 9 10 4 5 5 10 #6 10 10 5 10 6 5 6 10 10 10 10 10 10 10 10 10 6 4 5 10 -1 9 9 9 #6 10 10 6 1 6 10 10 10 10 10 10 6 5 9 10 10 6 10 10 10 -1 4 3 9 #9 7 5 10 10 10 4 8 -1 -1 6 4 4 6 10 9 6 10 9 10 1 6 10 10 10 #10 -1 6 10 10 9 10 10 2 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 #10 10 10 10 10 -1 1 10 10 1 1 10 10 1 -1 10 1 10 10 10 10 10 10 9 10 #11 11 -1 6 1 6 -1 10 6 4 8 10 10 10 10 8 10 10 10 10 10 11 6 12 12 #10 4 10 10 6 4 -1 4 -1 4 4 4 4 4 4 4 -1 4] #Unique: 13 print("resultList: ") print(str(type(resultList))) for s in resultList[:2]: print(*s) #<class 'list'> #resultList: #namedResult_tuple(lat=43.646556, lng=79.470988, guid='5761688733', ...) #namedResult_tuple(lat=43.645314, lng=-79.462791, guid='5761688679', ...) #...中的工作原理有疑问。我已经使下面的代码工作，我注意到我可以多次调用mainloop函数。这使得球每次被召唤时移动得更快。我想在没有多次按下按钮的情况下重现它。

此外，有人可以解释一下如何按下＆＃39; go＆＃39;按钮几次使球变得更快。

after

Answer 1

    from tkinter import *

def speedup():
    global vit
    if vit>2:
        vit-=2
        can1.after(500,speedup)

def bouge():
    global speedx,speedy,run,i

    colors=["white", "black", "red", "green", "blue", "cyan", "yellow"]

    pos = can1.coords(oval1)
    if pos[0] <= 0 or pos[0] >= 450:
        speedx *= -1
        can1.itemconfig(oval1,fill=colors[i])
        i+=1
        i=i%6
    if pos[1]<=0 or pos[1]>=450:
        speedy*=-1

    can1.move(oval1, speedx, speedy)
    text1.configure(text=(pos,vit))

    if run:
        can1.after(vit, bouge)


def stop():
    global run
    run=False

def start():
    global run
    run=True
    bouge()
    speedup()

x1, y1 = 100, 250
speedx=6
speedy=7
run=True
i=0
vit=100
fen1 = Tk()
fen1.title("Arkanoid made by Rico")
can1 = Canvas(fen1, height=500, width=500,background='lightblue')
oval1 = can1.create_oval(x1, y1, x1 + 50, y1 + 50, fill='yellow')
rec1=can1.create_rectangle(225,480,275,500,fill='grey')
pos=can1.coords(oval1)
Button(fen1, text='GO!!', command=start).grid(row=2, column=1, sticky=S)
Button(fen1, text='Quitter', command=fen1.quit).grid(row=2, column=3, sticky=S)
Button(fen1, text='Stop', command=stop).grid(row=2, column=2, sticky=S)
text1=Label(fen1,text=pos)
text1.grid(row=2,column=4)
can1.grid(row=1,columnspan=5)

fen1.mainloop()

多次调用函数后tkinter
