如何在 python tkinter 中制作条目小部件在按下回车键时给我其中的文本
how to make entry widget in python tkinter give me the text inside it on pressing enter key
所以，最近，我在 python Tkinter 上制作这个游戏，电脑随机给我一个单词，我必须输入我在单词中看到的单词和字母，所以这里的问题是，“ans”
是一个条目小部件，我希望它的工作方式是，一旦我输入完我在给定单词中看到的单词或字母，我应该按下回车键，当我按下回车键时，计算机应该看到小部件内写的任何内容，并且把它放在一个变量中，这样我就可以将该变量键入屏幕右侧 (a1-a18) 标签的文本，然后按回车键它应该完成所有这些操作，并删除之前写在里面的所有内容输入小部件

如果有人知道我该怎么做以及在这段代码中的什么地方添加它，请告诉我。

要绑定 return/enter 键，请使用 entry.bind("<Return>", func):
from tkinter import *
class UI:
def __init__(self):
self.entry = Entry(root)
# Bind the return key
self.entry.bind("<Return>", self.func)
self.entry.pack()
def func(self, event):
print(self.entry.get())
root = Tk()
UI()
root.mainloop()
试试这个：
def word():
global ans
...
ans = Entry(side, ...)
ans.grid(...)
ans.bind("<Return>", enter_pressed)
...
def enter_pressed(event):
print(ans.get())
ans.delete(0, "end")
此外，我建议您查看一些编程教程和 this。
这是一种不使用 global 的方法（因为我听说它们是“邪恶的”）：
from tkinter import Entry, Tk
def func(event):
print(event.widget.get())
event.widget.delete(0, 'end')
def main():
root = Tk()
entry = Entry(root)
entry.pack()
entry.bind('<Return>', func)
root.mainloop()
main()
