有没有办法测试tkinter条目是否包含特定单词？

Question

我使用tkinter进行输入和按输入框搜索，如果输入框包含特定单词（例如：Bachember），是否有代码我可以编写它来向我发送消息 谢谢

Answer 1

from tkinter import *
from tkinter import messagebox
root = Tk()
def check_entry():
    v = ent.get()
    if v == "hello world":
        print("hello world")
    else:
        messagebox.showerror("it is not hello world")
        print("write hello world")
        ent.delete(0,END)
ent = Entry(root)
button = Button(root,text="Click me",command=check_entry)
ent.pack()
button.pack()
root.mainloop()

Answer 2

from tkinter import *

root = Tk()
ent = Entry(root)
ent.pack()
def task():
    print("hello world" in ent.get())
    root.after(1, task)  # reschedule event in 2 seconds

root.after(1, task)
root.mainloop()

Answer 3

@Sujay告诉你要用这样的东西：

import tkinter as tk
from tkinter.messagebox import showinfo


def check_word_in_entry(*args):
    user_input = entry.get()
    # If you don't want casing to matter, change this to:
    # if "hi" in user_input.lower():
    if "hi" in user_input:
        # print("The word \"hi\" is inside the entry.")
        showinfo(message="The word \"hi\" is inside the entry.")


root = tk.Tk()
root.geometry("400x400")

variable = tk.StringVar(root)
variable.trace("w", check_word_in_entry)

entry = tk.Entry(root, textvar=variable)
entry.pack()

root.mainloop()

每次更改条目中的文本时，它都会调用check_word_in_entry。它检查"hi"是否在条目的文本中
