我希望能够返回分配给分配给活动函数的变量的值，但是如果该函数未激活，我希望能够返回{strong>相同的<{1}} 变量，但分配给不同的功能。下面的代码块是我想要的：
0如您所见，此def draw(x):
if not hasattr(draw, 'counter'):
draw.counter = 0
draw.counter += 1
global drawing
q.put(x)
process = False
drawingLock.acquire()
if not drawing:
process = True
drawing = True
drawingLock.release()
if process:
if not q.empty():
x()
drawingLock.acquire()
drawing = False
drawingLock.release()
print('`draw` has been called {} times'.format(draw.counter))
h = draw.counter
def walk():
if not hasattr(walk, "counter"):
walk.counter = 0
walk.counter += 1
penup()
forward(letter_width + space_width)
pendown()
print('`walk` has been called {} times'.format(walk.counter))
global w
w = 0 if walk is False else walk.counter
onkey(walk, "space")
def draw_newline():
# This funtion will pick up the turtle and move it to a second line below HELLO
penup()
goto(xcor() -(((space_width + letter_width)*(draw.counter)) + (space_width * w)) , ycor() -(letter_height + letter_height/2))
pendown()
def handle_enter():
draw.counter = 0
walk.counter = 0
def Carriage_functions():
draw_newline()
handle_enter()
onkey(Carriage_functions, "Return")
函数：
walk()每次在键盘上按下 def walk():
if not hasattr(walk, "counter"):
walk.counter = 0
walk.counter += 1
penup()
forward(letter_width + space_width)
pendown()
print('`walk` has been called {} times'.format(walk.counter))
global w
w = 0 if walk is False else walk.counter
onkey(walk, "space")
时在乌龟图形窗口中绘制一个空格，它还会计算它执行的次数：
SPACE然后，我将此值赋给全局声明的变量'w'，以便在下一个函数（if not hasattr(walk, "counter"):
walk.counter = 0
walk.counter += 1
）中使用，如下所示：
draw_newline()问题是每当我将global w
w = 0 if walk is False else walk.counter
分配给w的{{1}}函数时，就像这样：
draw newline()我收到此错误：
goto()即使goto(xcor() -(((space_width + letter_width)*(draw.counter)) + (space_width * w)) , ycor() -(letter_height + letter_height/2))
是全局定义的！我在这里做错了什么？
编辑：我甚至试过这个：
in draw_newline
goto(xcor() -(((space_width + letter_width)*(draw.counter)) + (space_width * w)) , ycor() -(letter_height + letter_height/2))
NameError: name 'w' is not defined
仍然没有运气。我刚收到这个错误：
w即使我在def walk():
if not hasattr(walk, "counter"):
walk.counter = 0
global counter
walk.counter += 1
penup()
forward(letter_width + space_width)
pendown()
print('`walk` has been called {} times'.format(walk.counter))
global h
h = walk.counter
if walk == False:
w = 0
elif walk == True:
w = h
函数后面放了相同的代码块，我仍然会遇到同样的错误。
