替换Tkinter Text小部件中的特定单词

Question

我想知道Tkinter文本小部件中是否可以替换特定单词的所有实例。
例如

假装这是我的文本小部件：
Hello how are you? How is the weather?

我想按下一个按钮，并将单词“ how”的所有实例替换为单词“ python”

Hello python are you? python is the weather?

我可能需要使用search（）函数，但是我不确定该怎么做。

感谢您的帮助：）

Answer 1

这是一个有效的代码：

import tkinter as tk


text = "Hello how are you? How is the weather?"
def onclick():
    text_widget.delete("1.0", "end")   #Deletes previous data
    text_widget.insert(tk.END, text.replace("how","python").replace("How","python"))   #Replacing How/how with python

root = tk.Tk()
text_widget = tk.Text(root)
text_widget.insert(tk.END, text)  #inserting the data in the text widget
text_widget.pack()

button = tk.Button(root, text = "Press me!", command = onclick)
button.pack()

root.mainloop()
