Question

我是Python的新手，也是Tinkter的新手。我正在试图通过一个应用程序跟踪烧坏的灯泡。我想要一个黄色方框网格，一旦点击就会变成灰色。我正在尝试调试错误：

Traceback (most recent call last):
  File "C:\Python32\new2.py", line 32, in <module>
    draw_rectangles()
  File "C:\Python32\new2.py", line 29, in draw_rectangles
    cell_zone.create_rectangle(place, 25, place+25, 50, fill=color)
  File "C:\Python32\lib\tkinter\__init__.py", line 2194, in create_rectangle
    return self._create('rectangle', args, kw)
  File "C:\Python32\lib\tkinter\__init__.py", line 2173, in _create
    *(args + self._options(cnf, kw))))
_tkinter.TclError: unknown color name "42593256color"

“42593256color”每次显示不同的随机数。

from tkinter import *
master = Tk()

columns = 5
clicked = False

cell_zone = Canvas(master, width=500, height=500)
cell_zone.pack()

def color():
    if clicked == True:
        #color = "grey"
        pass
    if clicked == False:
        #color = "yellow"
        pass


def draw_rectangles():
    for i in range(1, columns+1):
        place = i * 50
        print(place)
        #cell_zone.create_rectangle(place, place, place*1.2, place*1.2, fill="yellow")
        #cell_zone.create_rectangle(25, 25, 50, 50, fill="yellow")
        #cell_zone.create_rectangle(75, 25, 100, 50, fill="green")
        #cell_zone.create_rectangle(125, 25, 150, 50, fill="pink")
        #cell_zone.create_rectangle(place, 25, place+25, 50, fill="yellow", command=button_color())
        print(color)
        cell_zone.create_rectangle(place, 25, place+25, 50, fill=color)

color()
draw_rectangles()


mainloop()

由于color是一个函数，也许你有意这样做：

cell-zone.create_rectangle(...fill=color())

请注意使用()调用函数来获取颜色。但是，由于color()实际上并没有返回颜色，因此也会失败。

您是否打算让color持有颜色，返回颜色或其他内容？

Tkinter未正确设置颜色
