Python中Tkinter的问题 [英] Problems with Tkinter in Python

问题描述

topFrame=Frame(root)
topFrame.pack()
bottomFrame=Frame(root)
bottomFrame.pack(side=BOTTOM)

one=Label(root, text="one", bg="black", fg="white")
two=Label(root, text="Two", bg="white", fg="black")
three=Label(root, text="three", fg="purple", bg="green")
one.pack()
two.pack(fill=X)
three.pack(side=LEFT, fill=Y

button1=Button(topFrame, text="Button1", fg="red")
button2=Button(topFrame, text="Button2", fg="green")
button3=Button(topFrame, text="Button3", fg="blue")
button4=Button(bottomFrame, text="Button4", fg="purple")


button1.pack(side=LEFT)
button2.pack(side=LEFT)
button3.pack(side=LEFT)
button4.pack(side=BOTTOM)



root.mainloop()

为什么第13行会出错，语法无效？

第13行是：

Why does line 13 give an error, "Invalid Syntax"?
Line 13 is:

button1=Button(topFrame, text="Button1", fg="red")

推荐答案

因为第11行不完整：

Because line 11 is incomplete:

three.pack(side=LEFT, fill=Y

它需要一个右括号。

It needs a closing parenthesis.
