Clear an entry boxes in the new window

Question

I'm trying to clear my entry boxes in the new window, but it doesn't work. Can somebody help me to solve this problem? Here is my code below.

from tkinter import *
from tkinter import ttk

def new_deal():

    def add_new_deal():
        for each_entry in entry:
            each_entry.delete(0, END)

    def close_new_deal():
        new_deal_window.destroy()
        button_new_deal['state'] = 'normal'

    def user_input():
        symbol_label = Label(new_deal_window, text="Ticker")
        symbol_label.place(x=10, y=50)
        screener_label = Label(new_deal_window, text="Screener")
        screener_label.place(x=10, y=80)
        exchange_label = Label(new_deal_window, text="Exchange")
        exchange_label.place(x=10, y=110)
        number_label = Label(new_deal_window, text="Number")
        number_label.place(x=10, y=140)
        sum_label = Label(new_deal_window, text="Sum")
        sum_label.place(x=10, y=170)
        symbol_entry = Entry(new_deal_window)
        symbol_entry.place(x=100, y=50)
        screener_entry = Entry(new_deal_window)
        screener_entry.place(x=100, y=80)
        exchange_entry = Entry(new_deal_window)
        exchange_entry.place(x=100, y=110)
        number_entry = Entry(new_deal_window)
        number_entry.place(x=100, y=140)
        sum_entry = Entry(new_deal_window)
        sum_entry.place(x=100, y=170)
        return symbol_entry, screener_entry, exchange_entry, number_entry, sum_entry

    button_new_deal['state'] = ['disabled']
    new_deal_window = Toplevel(main_window)
    new_deal_window.geometry("400x500")
    new_deal_window.title("New deal")
    entry = user_input()
    button_add_deal = Button(new_deal_window, text="Add deal", command=add_new_deal())
    button_add_deal.pack()
    new_deal_window.protocol("WM_DELETE_WINDOW", close_new_deal)

# Create main window
main_window = Tk()
main_window.geometry("1280x960")
main_window.title("Invest monitor")
icon = PhotoImage(file='clipart3605240.png')
main_window.iconphoto(True, icon)
# Create menubar
menubar = Menu(main_window)
main_window.config(menu=menubar)
program = Menu(menubar, tearoff=0)
menubar.add_cascade(label="Program", menu=program)
program.add_command(label="Exit", command=quit)
program.add_command(label="About")
# Create notebook
notebook = ttk.Notebook(main_window)
investment_portfolio_tab = Frame(notebook)
plans_tab = Frame(notebook)
notebook.add(investment_portfolio_tab, text="Investment portfolio")
notebook.add(plans_tab, text="Plans")
notebook.pack(expand=True, fill="both")
# Create button New Deal
button_new_deal = Button(investment_portfolio_tab, text="New deal", command=new_deal)
button_new_deal.pack()
# Initialize
main_window.mainloop()

As you can see, I'm trying to create a new TopLevel window "new_deal_window" in the function "new_deal". In continue, i'm creating some labels and entry boxes (which are supposed to be filled with some value) in the function called "user_input", and then i would like to clear this values whit the button "button_add_deal".

In my opinion, i have some issues whit the type conversation, but i don't know where it is exactly.

So, when you click `add deal`, it should clear all the entry boxes? — PCM, Aug 31 '21 at 14:01
Just a small suggestion: Avoid importing everything from a module. It may cause in some errors. Thanks. — IJ_123, Aug 31 '21 at 14:37
Does this answer your question? [Why is the command bound to a Button or event executed when declared?](https://stackoverflow.com/questions/5767228/why-is-the-command-bound-to-a-button-or-event-executed-when-declared) — acw1668, Sep 01 '21 at 05:31

I think that you could clear each Entry alone . To do this :

entry_name.delete('0','end')

Or,you coud also do the following :

def clear(*args):
    for i in args :
        i.delete('0','end')

then you have to pass all your entries as arguments to this function .

Please provide additional details in your answer. As it's currently written, it's hard to understand your solution. – Community Sep 03 '21 at 15:52
My solution is for each entry use 'entry_name.delete('0','end')' for exemple : sum_entry.delete('0','end') and do the same process for all your entries . – Ayyoub ESSADEQ Sep 03 '21 at 15:54
I edit my answer in order to minimise your code . – Ayyoub ESSADEQ Sep 03 '21 at 16:06
