#31258 — Tkinter how to access the widget by name

I'm a little teapot ... himself the question: if I want to appeal to the widget, knowing his name... ?

# appropriated the name of the widget
label = Label(frame, width = 40, text='text', name = 'name')
...
name_='name'
configure(name_)
...
def configure(name_)
        #And how can that be?
        # At least let the text you want to change ....

I beg you ..!!!!

I am unfamiliar with Tkinter, so this might not be very helpful.

Usually with the GUI I have created before I uses classes and store 
the widgets inside the classes. That makes it easier to use
`self.widgetname` or `getattr(self, widgetname)`. If that is not
something you can instead store the attributes in a list/dictionary.
In both cases make sure not to have multiple widgets created with
the same name.

Note the following is all untested and should be considered pseudo-code.

widgets = {}
label = Label(frame, width = 40, text='text', name = 'name')
widgets['name'] = label

def configure(name_):
    widget = widgets[name_] 

OR

widgets = []
label = Label(frame, width = 40, text='text', name = 'name')
widgets.append( label )

def configure(name_):
    found = False
    for w in widgets:
         if w.name == name_: # No idea how to get name from Tk widget
               found = True
               break
     if found:
        # configure here

ok thanks, that this method is suitable in full: "widgets.append( label )" , аlthough at the beginning wanted to access the widget by its internal name, but I left this venture )).

I do not understand your question, but I think you want something like

def configure(name):   ## note that a colon is required here
   name.configure(bg='green')
   #  or
   name['bg']='green'

label_1 = Label(frame, width = 40, text='text')
configure(label_1)
label_2 = Label(frame, width = 40, text='label_2')
configure(label_2)

If this is not what you want, post an example that is more specific.
