当我运行程序时,GUI没有出现在桌面上
from tkinter import *
root = Tk()
label1 = Label(root, text="Bench")
label2 = Label(root, text="Deadlift")
label3 = Label(root, text="Squat")
label1.grid(row=0, sticky=E)
label2.grid(row=1, sticky=E)
label3.grid(row=2, sticky=E)
e1 = Entry(root)
e2 = Entry(root)
e3 = Entry(root)
e1.grid(row=0, column=1)
e2.grid(row=1, column=1)
e3.grid(row=2, column=1)
l2 = Label(root)
def callback():
total = sum(int(e.get()) for e in (e1, e2, e3))
l2.config(text="answer = %s" % total)
b1 = Button(root, text="enter", command=callback)
b1.pack()
l2.pack()
root.mainloop()
我希望GUI出现。任何答案都非常感谢,我是一个初学者,正在尝试解决这个问题。

当您使用.pack和.grid时发生冲突。您只需将.pack更改为.grid并修复def Label,.config并不是标签的有效参数,因此将其放入函数中即可解决问题。
from tkinter import *
root = Tk()
label1 = Label(root, text="Bench")
label2 = Label(root, text="Deadlift")
label3 = Label(root, text="Squat")
label1.grid(row=0, sticky=E)
label2.grid(row=1, sticky=E)
label3.grid(row=2, sticky=E)
e1 = Entry(root)
e2 = Entry(root)
e3 = Entry(root)
e1.grid(row=0, column=1)
e2.grid(row=1, column=1)
e3.grid(row=2, column=1)
def callback():
total = sum(int(e.get()) for e in (e1, e2, e3))
Label(root, text="answer = %s" % total).grid(row=3, column=1)
b1 = Button(root, text="enter", command=callback).grid(row=3)
root.mainloop()
我希望这会有所帮助:)
