Answer 1

你应该设置一个函数，并在函数中执行此操作command

import tkinter

def press():

    global to_download

    if to_download:

        print(to_download)

        window.destroy()

window = tkinter.Tk()

window.configure(background="grey90")

window.title("Downloader")

window.geometry("300x300")

window.resizable(False, False)

entry = tkinter.Entry(window)

entry.place(x=70,y=68)

entry.configure(highlightbackground="grey90")

button = tkinter.Button(window, text="Download",

command=press, highlightbackground="grey90")

button.place(x=110,y=120)

window.mainloop()

Answer 2

此行可能不小心从原始代码中省略。它应该插入到 press 函数中 if 语句之前：

to_download = entry.get()

以下是完整的代码：

import tkinter

def press():

    global to_download

    to_download = entry.get()

    if to_download:

        print(to_download)

        window.destroy()

window = tkinter.Tk()

window.configure(background="grey90")

window.title("Downloader")

window.geometry("300x300")

window.resizable(False, False)

entry = tkinter.Entry(window)

entry.place(x=70,y=68)

entry.configure(highlightbackground="grey90")

button = tkinter.Button(window,

                        text="Download",

                        command=press,

                        highlightbackground="grey90")

button.place(x=110,y=120)

window.mainloop()
