How to know if a given widget is focussed?

[BhagyaJyoti22006]

import customtkinter as tk

def check_focus(widget):
    widget.focus_set()
    root.update()
    focused_widget = root.focus_get()
    if focused_widget.winfo_name() == widget.winfo_name():
        print(f"The widget is focused.")
    else:
        print(f"The widget is not focused.")

root = tk.CTk()

entry = tk.CTkEntry(root)
button = tk.CTkButton(root, text="Check Focus", command=lambda: check_focus(entry))

entry.pack(padx=10, pady=10)
button.pack(pady=10)

root.mainloop()`

Even if i have focussed on entry widget, i get false. I printed them when I have widget selected and got output: focussud- .!ctkentry.!entry widget- .!ctkentry

They both are same still printing different values. How, help?
