,我不知道是什么导致了它,我查看了其他帖子,但没有任何东西帮助我了解发生了什么
下面是导致它的代码
def showhwk(lesson, popup):
lesson = lesson.replace("/","")
popup.withdraw()
show = Tk()
show.title("Homework marks for "+lesson)
show.geometry("+{}+{}".format(positionRight, positionDown))
try:
with open(lesson+".csv", "r") as show:
csvlist = list(csv.reader(show))
for label in range (len(csvlist)):
Label(show, text = "hello").grid(row = label)
except FileNotFoundError:
show.title("Error!")
error = Label(show, text = "Homework file was not found")
error.grid(row = 0)
def goback3(show):
popup.deiconify()
show.withdraw()
returnbut = Button(show, text = "Return", bg = "#79838e", command = lambda: goback3(show)).grid(row = 40, sticky = W+E)
这是全部错误:

首先定义show
如下:
show = Tk()
稍后,使用以下语句将show
重新定义为打开的文件句柄:
with open(lesson+".csv", "r") as show:
然后,尝试使用show
作为小部件的主控:
Label(show, text = "hello").grid(row = label)
因为
show
不再是一个小部件,所以它不能用作另一个小部件的主程序。这就是您出现tkinter错误的原因。向我们显示完整错误,请:)现在已经这样做了,谢谢您正在使用上下文管理器重新分配中的show
,请正确设置错误格式。请显示从您发布的示例中得到的错误。错误与代码不匹配
