entry组件创建：

from tkinter import *

windows = Tk()

windows.title("test")
windows.configure(bg="blue")

label1 = Label(windows, text="account")
label1.grid(column=0, row=0)
label2 = Label(windows, text="passwd")
label2.grid(column=0, row=1)

entry1 = Entry(windows)
entry1.grid(column=1, row=0)

entry2 = Entry(windows)
entry2.grid(column=1, row=1)

windows.mainloop()

效果如下：

清空输入框

delete方法

使用方法如下

from tkinter import *

windows = Tk()

windows.title("test")
windows.configure(bg="blue")


def delete():
    entry1.delete(0, END)
    entry2.delete(0, END)

label1 = Label(windows, text="account")
label1.grid(column=0, row=0)
label2 = Label(windows, text="passwd")
label2.grid(column=0, row=1)

entry1 = Entry(windows)
entry1.grid(column=1, row=0)

entry2 = Entry(windows)
entry2.grid(column=1, row=1)

button1 = Button(windows, text="按钮", command=delete)
button1.grid(column=1, row=2, columnspan=2)

windows.mainloop()

给按钮绑定函数中加入清空输入框方法，点击按钮后，即会清空输入框中的内容

获取输入框中的内容

有时候我们还需要获取输入框中的内容，比如获取用户输入的账号和密码与数据库中的账号密码对比

使用get方法实现

实现方法如下

from tkinter import *

windows = Tk()

windows.title("test")
windows.configure(bg="blue")


def delete():
    print(entry1.get(), entry2.get())


label1 = Label(windows, text="account")
label1.grid(column=0, row=0)
label2 = Label(windows, text="passwd")
label2.grid(column=0, row=1)

entry1 = Entry(windows)
entry1.grid(column=1, row=0)

entry2 = Entry(windows)
entry2.grid(column=1, row=1)

button1 = Button(windows, text="按钮", command=delete)
button1.grid(column=1, row=2, columnspan=2)

windows.mainloop()

给按钮绑定打印输入框值的函数，按下后将打印输入框的值，如下图所示：
