tkinter返回。！而不是条目的文字内容

Question

我正在制作一个程序，并使用tkinter和tkinter grid将其返回，但是当我尝试获取entry> entry中的值时'工作！

我在互联网上查找了解决方案，但其中没有一个包括网格除此之外：
tkinter文本输入的返回值，关闭GUI 太难了！

到目前为止，这是我的代码：

# import tkinter module
from tkinter import *
from tkinter.ttk import *

# creating main tkinter window/toplevel
master = Tk()

# this will create a label widget
l1 = Label(master, text = "First:")
l2 = Label(master, text = "Second:")

# entry widgets, used to take entry from user
e1 = Entry(master)
e2 = Entry(master)
def input_():
    title = e1.get()
    body = e2.get()
    print(e1)
    print(e2)
# grid method to arrange labels in respective
# rows and columns as specified
l1.grid(row = 0, column = 0, sticky = W, pady = 2)
l2.grid(row = 1, column = 0, sticky = W, pady = 2)
submit = Button(master, text="Submit", command=input_)

# this will arrange entry widgets
e1.grid(row = 0, column = 1, pady = 2)
e2.grid(row = 1, column = 1, pady = 2)
submit.grid(row = 3, column = 1, pady = 2)

# infinite loop which can be terminated by keyboard
# or mouse interrupt
mainloop()

Answer 1

这可能是因为在输入函数中，您正在打印

print(e1)
print(e2)

entry对象。您可能一直在尝试打印title和body，这些被提取但未使用。
