I think it's called an OptionMenu ...

Thank you @vegaseat.
@vegaseat, look at line 29 of your code please. As you typed on the code, we need to have line 29 in our file from the beginning of running the program.
I mean i want to use
load_choices for example instead of line 29. I want to load the choices list from a text file (my db file), and send it into() in lime 30.
What should i do?
No idea what your file looks like.
# let's assume your data is read from a file like this data = '''\ red green blue yellow white ''' choices = [color for color in data.split()] print(choices) ''' result ... ['red', 'green', 'blue', 'yellow', 'white'] '''
This a the first part of my code:
import os import pickle DBFILENAME = 'linknames.db' loaded = True choices =  def pathtofile(filename = DBFILENAME): folder = os.path.dirname(os.path.abspath(__file__)) return os.path.join(folder, filename) def load_choices(): global choices, loaded if loaded: return filepath = pathtoile() if not os.path.isfile(filepath): with open(filepath, 'wb') as fout: pickle.dump(, fout) with open(filepath, 'rb') as fin: choices = pickle.load(fin) loaded = True def dump_choices(): filepath = pathtofile() with open(filepath, 'wb') as fout: pickle.dump(choices, fout) import sqlite3 as db conn = db.connect('linkuserpass.db') cursor = conn.cursor() cursor.execute('CREATE TABLE IF NOT EXISTS linkuserpass(mylink TEXT, myusername TEXT, mypassword TEXT)') print ('table is created') conn.commit() cursor.close() conn.close() def add(): import sqlite3 as db link = ent1.get() user = ent2.get() password = ent3.get() conn = db.connect('linkuserpass.db') cursor = conn.cursor() cursor.execute('INSERT INTO linkuserpass(mylink, myusername, mypassword) VALUES(?,?,?)', (link, user, password)) print ('Done!') conn.commit() cursor.close() conn.close() load_choices() choices.append(ent1.get()) dump_choices() def show(): import sqlite3 as db key_link = var.get() conn = db.connect('linkuserpass.db') conn.row_factory = db.Row cursor = conn.cursor() cursor.execute('SELECT * FROM linkuserpass WHERE mylink=(?)' , (key_link,)) row = cursor.fetchone() data_str1 = "" data_str2 = "" data_str1 = (row['myusername']) data_str2 = (row['mypassword']) print data_str1 print data_str2 userlabel['text'] = 'username: ' + data_str1 passwordlabel['text'] = data_str2 conn.commit() cursor.close() conn.close()
And the rest is the Tkinter code part. Look at this please:
var = StringVar(root) var.set('') load_choices() option = OptionMenu(root, var, choices) option.pack() btn2 = Button(frame5, text = 'show', command = show) btn2.pack(side = 'left')
load_choices that i have typed, when i run the program, no value will be shown on the option menue, its empty.
What should i do?
Make sure the data is presented to the OptionMenu() as a list that is unpacked with the * operator. Testprint choices and use *choices as an argument.
