error using an entry to bring database parameters

Question

I am trying to bring what I have in my database and I want to show it using an read button I should introduce an ID in an entry and after pressing read button it should show all parameters from the database inside of the rest of entries

I am doing the next sentence but it does not work (you can see that I am doing entry by entry because I don't know how to do all the entries at the same time)

def buttonRead():

mi_conexion=sqlite3.connect('Usuarios')

mi_cursor=mi_conexion.cursor()

valor=mi_cursor.execute('SELECT NOMBRE_USUARIO FROM DATOSUSUARIOS WHERE ID='  + cuadroId.get())

nombre.set(valor)

mi_conexion.commit() 

mi_conexion.close() 

nombre=StringVar()

cuadroNombre=Entry(miFrame,textvariable=nombre)

It appears the next error inside of the entry (nombre) <sqlite3.Cursor object at 0x0000000002924030>

I am using Python3 and SQLLite

I hope that you understand me

Thank you
