[英]Replace specific word in Tkinter Text widget
我想知道是否有辦法替換 Tkinter Text 小部件中特定單詞的所有實例。
例如
假設這是我的文本小部件:
Hello how are you? How is the weather?
我想按下一個按鈕,用“python”這個詞替換“how”這個詞的所有實例
Hello python are you? python is the weather?
我可能需要使用 search() 函數,但我不確定從那里開始做什么。
謝謝你的幫助 :)
這是一個工作代碼:
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()
