Auto Bracket Closing in Tkinter-CodePudding

I'm making a code editor and everything is good! But I want to make a feature which auto closes your bracket (testing with letter 'a'). Here is my code: (bracket close part)

st is my scolled text and self is the root window, I am testing with when you press 'a' but it inserts the bracket before the key ('a') is added into the text box.

#bracket open and close

    def bo(event):
      print("hello")
      self.st.insert(END, ")")
      
      return

    
    self.st.bind('<KeyPress-a>', bo)

Thank you! Have a good day!

Use the KeyRelease event instead, otherwise your function call is executed before the actual letter is inserted into your Text widget.

from tkinter import Tk, Text, END

def bo(event):
    st.insert(END, ")")

root = Tk()
st = Text(root)
st.bind("<KeyRelease-a>", bo)
st.pack()
root.mainloop()
