How to remove wildcard character in tkinter text?

Question

I want to remove every text inside < >. I used to replace('<*>',' ') but it does not remove them at all.

For example, my text is "<a/ddff>Nitin Hardeniya - 2015 - ‎Computers" I want it to turn into "Nitin Hardeniya - 2015 - ‎Computers".

Please advise me on how should I correct my code.

Here is code:

import tkinter as tk

root = tk.Tk()
text = root.clipboard_get()
def onclick():
    text_widget.delete("1.0", "end")   
    text_widget.insert(tk.END, text.replace('<*>',' '))   

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()

You need to use a regular expression for such matching. the <*> in your line: text.replace('<*>',' ') is not a regular expression it is a strict match (see replace function documentation)

A way of doing it is

def onclick():
    original = text_widget.get("1.0", "end")   
    pattern = re.compile(r'(<[^<>]+>)')
    fixed= pattern.sub(r" ", original )
    text_widget.delete("1.0", "end")   
    text_widget.insert(tk.END, fixed)

Hi, thank you for telling me. however fixed= pattern.sub(r" ", original ) is not used. And it does not work. – ankerbow May 16 '20 at 08:37
Sorry replace orignal by fixed in the tkinter entry. – Jean-Marc Volle May 16 '20 at 08:43
