在循环中使用turtle的onclick

时间:2019-05-31 03:38:45

标签: python python-3.x onclick turtle-graphics

我正在尝试根据函数中的dict个字符串创建一个简单的接口。每个字符串用于显示文本和一个可单击的乌龟(使用onclick()使该乌龟可单击)。这样一来,我可以单击乌龟,然后输入一些值。

但是,如果我理解正确的话,当函数完成通过字典的循环运行时,该循环应定义的所有变量都被重新定义为通过该循环的最后一个变量,即字典的最后一个元素。因此,onclick()函数仅向我返回字典的最后一个元素。

有没有一种方法可以使一个onclick()函数对字典的每个元素进行不同的反应/对应?我真的不想为字典的每个元素编写一堆onclick()函数。我正在尝试学习更好的方法。

list_alunos={'joao': ['5', 'm'],'maria': ['5', 'm'],'lobo': ['5', 'm'],'mau': ['5', 'm']}
def caca(dictx,file):
    import turtle
    mes=file
    vert=350
    hor=-600


    def got(t,x,y,d) :
        t.penup()
        t.goto(x,y)
        t.pendown()
        t.seth(d)

    def text(t,text, size, color, pos1, pos2):
        t.penup()
        t.goto(pos1, pos2)
        t.color(color)
        t.begin_fill()
        t.write(text, font=('Arial', size, 'normal'))
        t.end_fill()




    new_vert = vert
    for key in dictx:
        nome = key
        if vert == -340:
            new_vert = 350
            new_hor = hor + 250
        if vert!= -340:
            new_vert= new_vert-30
            new_hor = hor
            txt_vert = new_vert - 15
            txt_hor = new_hor + 20

        screen = turtle.Screen()

        width = 1200
        height = 1500
        turtle.screensize(width, height)



        tnome = turtle.Turtle(shape='turtle')
        tnome.color('pink')
        textnome = turtle
        tnome.speed('fastest')
        textnome.speed('fastest')

        text(textnome, '%s' %(nome), '20', 'pink', txt_hor,txt_vert)

        got(tnome,new_hor,new_vert,0)
        def tnome_handler(x, y):

            pos = list(dictx.keys()).index(nome)
            listt = list(dictx)

            pnt = screen.textinput(' pontuação', '%s:  '%(listt[pos]))
            pnt = [int(x) for x in pnt.split()]
            if len(pnt) == 5 :
                with open('%s.py' %(mes), 'a') as fd:
                    fd.write('\n%s.pontuacao(%i,%i,%i,%i,%i)' % (nome,pnt[0],pnt[1],pnt[2],pnt[3],pnt[4]))
                tnome.color('blue')
        tnome.onclick(tnome_handler)

我相信以下代码重做可以实现您想要的。它有效地为每个唯一响应的乌龟/按钮生成了一个自定义处理程序:

from turtle import Screen, Turtle

WIDTH, HEIGHT = 1200, 1500

dict_alunos = {'joao': ['5', 'm'], 'maria': ['5', 'm'], 'lobo': ['5', 'm'], 'mau': ['5', 'm']}

def text(t, text, size, color, x, y):
    t.penup()
    t.goto(x + size, y - size/2)
    t.color(color)
    t.write(text, align='left', font=('Arial', str(size), 'normal'))
    t.goto(x, y)

def caca(dictionary, mes):

    def tnome_handler(nome, turtle, x, y):

        pnt = screen.textinput('pontuação', '%s:  ' % (nome))
        pnt = [int(x) for x in pnt.split()]

        if len(pnt) == 5:
            with open('%s.py' % (mes), 'a') as fd:
                fd.write('s.pontuacao(%i, %i, %i, %i, %i)\n' % (nome, pnt[0], pnt[1], pnt[2], pnt[3], pnt[4]))

        turtle.color('blue')

    vert = 350
    hor = -600

    new_vert = vert

    for nome in dictionary:

        if vert == -340:
            new_vert = 350
            new_hor = hor + 250

        if vert != -340:
            new_vert = new_vert - 30
            new_hor = hor
            txt_vert = new_vert - 15
            txt_hor = new_hor + 20

        turtle = Turtle(shape='turtle')
        turtle.color('pink')
        turtle.speed('fastest')
        turtle.setheading(0)

        text(turtle, '%s' % (nome), 20, 'pink', txt_hor, txt_vert)

        turtle.onclick(lambda x, y, n=nome, t=turtle: tnome_handler(n, t, x, y))

screen = Screen()
screen.setup(WIDTH, HEIGHT)

caca(dict_alunos, 'mm')

screen.mainloop()

我还重新编写了代码,以适应更常见的编程设计。
