通过在没有按钮的情况下在TKINTER / PYTHON的入口框中输入输入框，添加带有标签的额外行

Question

我想在不需要使用按钮的情况下在已经存在的输入框中键入一个数字后，看到新的标签和入口盒Apear。

我的循环可能也是错误的。但是我希望你有我的意图。这对我来说是全新的。

import tkinter as tk

window = tk.Tk()

label_amount = tk.Label(text="Amount")
label_amount.grid(row=0, column=0)

entry_amount = tk.Entry()
entry_amount.grid(row=0, column=1)

# TODO - create a label and entry * amount entered
# i = 1
# while i < int(entry_amount.get()):
#     label_container = tk.Label(text=f"Container {i}")
#     label_container.grid(row=i, column=1)
#
#     entry_container = tk.Entry()
#     entry_container.grid(row=i, column=2)
#
#     i = i + 1

window.mainloop()

Answer 1

它起作用。
这是最终代码。

import tkinter as tk

window = tk.Tk()


def function(event):
    # create a label and entry * amount entered
    if entry_amount.get() == "":
        return
    else:
        i = 1
        while i <= int(entry_amount.get()):
            label_container = tk.Label(text=f"Container {i}")
            label_container.grid(row=i, column=1)

            entry_container = tk.Entry()
            entry_container.grid(row=i, column=2)

            i = i + 1


window.bind("<Return>", function)

label_amount = tk.Label(text="Amount")
label_amount.grid(row=0, column=0)

entry_amount = tk.Entry()
entry_amount.grid(row=0, column=1)
entry_amount.focus()

window.mainloop()
