What I want the frame to do is that when I click on the 'clear' button, the frame is cleaned but it does not and when I enter a string that is not valid and then a valid one, it shows traces of the past and past action. I already tried changing the Label.grid () by a Label.pack (), but it is worse since the 'animation' looks like a stack without removing any element when the 'clear' button is pressed
This is basically what would make it change
from tkinter import *
import tkinter.ttk as ttk
def clear():
area.delete(0,END)
frame.config(bd=1, relief=SUNKEN)
frame.update()
status = Label(frame)
status.grid(row=0, column=0, sticky=NSEW)
def statusVal(value):
if not value == 0:
status = Label(frame, background="#ff4242", fg="#262626", text="Cadena invalida", anchor="center")
status.grid(row=0, column=0)
frame.config(bd=1, relief=SUNKEN, background="#ff4242")
frame.update()
else:
status = Label(frame, background="#56ed42", fg="#262626", text="Cadena valida", anchor="center")
status.grid(row=0, column=0)
frame.config(bd=1, relief=SUNKEN, background="#56ed42")
frame.update()
#Test
def validation():
capture = area.get()
if capture == '1':
return statusVal(0)
else:
return statusVal(1)
root = Tk()
root.geometry("300x150+300+300")
area = Entry(root)
area.grid(row=1, column=0, columnspan=2, sticky=E+W+S+N, padx=5)
frame = Frame(root, bd=1, relief=SUNKEN)
frame.grid(row=2, column=0, padx=5, pady=5, columnspan=2, sticky=W+E+S+N)
frame.columnconfigure(0,weight=5)
frame.rowconfigure(0,weight=5)
abtn = Button(root, text="Validate", command=validation)
abtn.grid(row=1, column=3)
cbtn = Button(root, text="Clear", command=clear)
cbtn.grid(row=2, column=3, pady=5)
root.mainloop()
See if this works better. The main change was to have the status Label always exist and hide or unhide it as desired — instead of creating a new one every time the validation() function was called. I also removed the code that was explicitly updating the frame which isn't necessary.

I've been following this website for a while. It is really helpful. So, thanks for all the useful tips.
I've been searching for this answer for the past two weeks without any success, so now I'm compelled to ask out of total frustration with my current obstacle.
How do you use StringVar as a list?
Basically, I was coding the following program for my wife. The code is pretty messy as it is my first program I've tried to code.
The idea was that I would take 3 variables; password, secret number and website and then do some work on them using if statements and lists to create a unique password.
First problem was that I couldn't restrict the character length of the entry widgets but in the end i solved that but i still want to limit the characters that can be input.
for instance in the website entry box, i want to allow only letters.
If I could convert StringVar to a list, I could do some work with messy if statements to allow only certain characters in each index but everythime i try it says that stringvars cant be used as a list.
I need them as a list to limit the type of characters that can be entered and also so that i can do work on the variables to get the final output.

# add functionality, fix validation
To restrict the type/number of characters that can be typed into an entry widget, you can use the entry validatecommand. Here is an example to allow only letters and another one to restrict the entry to 4 digits:
from tkinter import Tk, Entry, Label
def only_letters(action, char):
if action == "1":
# a character is inserted (deletion is 0) allow the insertion
# only if the inserted character char is a letter
return char.isalpha()
else:
# allow deletion
return True
def only_numbers_max_4(action, new_text):
if action == "1":
return new_text.isdigit() and len(new_text) <= 4
else:
return True
root = Tk()
# register validate commands
validate_letter = root.register(only_letters)
validate_nb = root.register(only_numbers_max_4)
Label(root, text="Only letters: ").grid(row=0, column=0)
e1 = Entry(root, validate="key", validatecommand=(validate_letter, '%d', '%S'))
# %d is the action code and %S the inserted/deleted character
e1.grid(row=0, column=1)
Label(root, text="Only numbers, at most 4: ").grid(row=1, column=0)
e2 = Entry(root, validate="key", validatecommand=(validate_nb, '%d', '%P'))
# %P is the new content of the entry after the modification
e2.grid(row=1, column=1)
root.mainloop()

Having trouble setting the file path that is selected by the user and setting to variable. I am able to retrieve the path and set it to display in the entry box but I would like to capture that path and import it into another script. Maybe my logic is flawed here? What am I doing wrong?

You do not need to use a textvariable, you can just use variable = entry1.get(). A Tkinter textvariable is not like a traditional python variable, it is just used for setting the text in an entry.
I'm pretty new to Python. I can MAKE things work, but I'm never really sure if I'm actually using best practices, so forgive me if I'm not explaining things correctly, or if my code isn't written using best practices. I'm working on it!
