Run functions from list

trying to get the selected values from a list of checkbutton without having to create 10 or more checbutton and var.
i got this to test the idea
from tkinter import Tk, StringVar, Checkbutton, Button, BooleanVar
root = Tk()
w, h = root.winfo_screenwidth(), root.winfo_screenheight()
root.geometry("%dx%d+0+0" % (w, h))
def def1():
print("1")
def def2():
print("2")
def def3():
print("3")
def def4():
print("4")
def def5():
print("5")
def def6():
print("6")
def letssee():
print(addlist)
nomtestes = ["def1", "def2", "def3", "def4", "def5", "def6"]
clltes = 0
rwwtes = 0
addlist=[]
username_cbs = dict()
for name in nomtestes:
if clltes == 5:
rwwtes += 1
clltes = 0
username_cbs[name] = Checkbutton(root, text=name, onvalue=True, offvalue=False)
username_cbs[name].var = BooleanVar()
username_cbs[name]['variable'] = username_cbs[name].var
username_cbs[name]['command'] = lambda w=username_cbs[name]: upon_select(w)
username_cbs[name].grid(row=rwwtes, column=clltes, pady=2)
clltes += 1
Button(root, text="OK",command=letssee).grid(column=0, row=5, padx=1, pady=15)
def upon_select(widget):
if widget.var.get() == True:
addlist.append(widget['text'])
else:
addlist.remove(widget['text'])
root.mainloop()
In this example im trying to print all the checkbuttons i selected, but, to run the funcions added to the addlist
Any ideia how to do this?
thanks

You can create a dictionary, mapping string values to respective functions, and then add or remove them to a list. You can add a function map and change the letssee() like this to check.
func_map = {"def1": def1, "def2": def2, "def3": def3, "def4": def4, "def5": def5, "def6": def6}
nomtestes = ["def1", "def2", "def3", "def4", "def5", "def6"]
def letssee():
print(addlist)
for i in addlist:
func_map[i]()
Out:['def2', 'def1']

How can I make a re-grading button from tkinter entry?

I was making a vocab test program and I was making a grading button. But I faced a problem that when I press the grading twice, grade, entries, right, wrong keeps appends and I can't find the way to reset these lists. So, when I press the grade button again after I correct the answer, the grading overlaps and makes an error.

How can I reset these lists so I can re-grade the answers? I've tried adding right=[] wrong=[] entries=[] grade=[] and also used another list to get rid of the overlapped values in the list,
def check():

test_try_list[test_try].append(entry) # save 'entry' into list
for i, e in enumerate(test_try_list[test_try]):
value = e.get()
i_list.append(i)
print(i_list)
if len(i_list) > 35:
for i in range(0, len(i_list)):
new_i_list.append(i_list[i] % 35)
for v in new_i_list:
if v not in new_i_list2:
new_i_list2.append(v)
print(new_i_list2)
but it still doesn't work. How can I make button to re-grade?

You can use grade.clear() to clear list
def check():
grade.clear()
or you have to use global to inform function that it has to assign new list to external/global variable
def check():
global grade
grade = []
But I would run it without all these lists
def check():
correct = 0
wrong = 0
for i, (e, expected) in enumerate(zip(entries, Day21_kor)):
value = e.get()
if value in expected:
correct += 1
label = Label(second_frame, text='O', fg='Blue')
else:
wrong += 1
label = Label(second_frame, text='X', fg= 'red')
label.grid(column=3, row=i)
percent = correct/(correct+wrong)
print('Correct:', correct, '| Wrong:', wrong, '| Percent: {:.1%}'.format(percent))
Result:
Correct: 0 | Wrong: 35 | Percent: 0.0%
Correct: 1 | Wrong: 34 | Percent: 2.9%

change button text, using button name

I have an issue, I created a table of buttons using a loop, and I saved the button's names in a list, now I want to change the text of the buttons when one button is clicked.
I don't konw how.
this is the loop where i create the table
def grid(n):
i = n*n
for widget in LeftFrame.winfo_children():
widget.destroy()
for i in range(n):
for row in range(n):
for col in range(n):
button = Button(LeftFrame, text=' ', width=12, height=6, command=lambda: checker(button, i))
button.grid(row=row, column=col)
button_identities.append(button)
and this is the function on click of the button
def checker(buttons, i):
print(i)
global click, button_identities
print(button_identities)
bname = (button_identities[i])
print(bname)
if buttons["text"] == ' ' and click == True:
buttons["text"] = 'X'
click = False
# scorekeeper()
elif buttons['text'] == ' ' and click == False:
buttons['text'] = 'O'
click = True
# scorekeeper()
there is a method to check the text from the button name in the last function

Try this:
from functools import partial
def grid(n):
for widget in LeftFrame.winfo_children():
widget.destroy()
for i in range(n):
for row in range(n):
for col in range(n):
button = Button(LeftFrame, text=' ', width=12, height=6)
# Assign the button a command
command = partial(checker, button)
button.config(command=command)
button.grid(row=row, column=col)
button_identities.append(button)
def checker(button):
# The argument is a button
global click
# If the cell is empty
if button.cget("text") == " ":
# If Xs are you play
if click:
# Change the text of the button
button.config(text="X")
click = False
# If Os are to play
else:
# Change the text of the button
button.config(text="O")
click = True
I usually use <widget>.cget("<parameter>") to get the parameter out of a widget and <widget>.config(parameter=<new value>) to assign it a new value. Also you can use functools.partial to pass in arguments for the button command.

so this is my take on this issue:
from tkinter import Tk, Button
root = Tk()
class EditableButton(Button):
def __init__(self, parent, row, col):
Button.__init__(self, parent)
self.parent = parent
self.row = row
self.col = col
self.tracker = 0
self.name_list = ['apple', 'pear']
print(len(self.name_list))
self.button = Button(self.parent, text=self.name_list[self.tracker], command=self.change_text)
self.button.grid(row=self.row, column=self.col)
def change_text(self):
if self.tracker < len(self.name_list) - 1:
self.tracker += 1
else:
self.tracker = 0
self.button.config(text=self.name_list[self.tracker])
n = 3
for row in range(n):
for col in range(n):
button = EditableButton(root, row, col)
root.mainloop()
basically what happens is You make a class that is like a template for buttons and each class object created by the loop is independent, each of them has their own spot in memory, so whenever You press the button it only calls the function in its own class

Python Tkinter Multiple buttons are getting created on clicking on radio buttons

These are few lines from my actual code - I am aware this is not the best way of writing a code, but as I am new and getting familiarize with Tkinter (py2) consider this as my scratch work.
I am listing a question and multiple options. When the user selects an option, a SUBMIT button is created and when clicks on SUBMIT button it will accordingly change the color of Option to green or red. If green then another NEXT button will be available to clean and move to next question.
The issue that I am facing is if a user selects option A but then without clicking the SUBMIT button selects another option the submit button multiplies. I want to destroy the unwanted buttons or even do not want to create multiple SUBMIT buttons.
Please do help in achieving the same.

As things are, each time press_button() is run, a new Button object is generated, and placed in the button_game variable. This does not remove or hide the previous button, which still exists in the packed UI.
A simple solution that would save the machine some work is to initialize the button only once, earlier in the code, but omit placing/displaying/packing it until that block within press_button() is run.

I was able to achieve what I was looking for with the help of config.
I created the SUBMIT button once at the beginning and then instead of calling the whole function again and again; I just replaced press_button with button_game.config(command = lambda: right(chapter, num_ques, topic, val))
Now I should write this code using class in python.

How to see which button is activated / determine right buttons are activated on python tkinter

I'm making a game that finding seven right buttons(It has a fixed answer) among 12 buttons by using tkinter. There are a total of 12 buttons, and only if all seven of them are clicked will win the game.
I'm curious about how to make the window to see which button is activated or inactivated, and how to make a function to determine whether one wins or loses. (when seven specific buttons are activated, it wins.)
++
game1=tkinter.Tk()
game1.title("Test")
game1.geometry("600x450")
button1 = Button(game1, text=' 1 ', fg='black', bg='red',
height=3, width=10)
button1.place(x=0,y=300)
button2 = Button(game1, text=' 2 ', fg='black', bg='red',
height=3, width=10)
button2.place(x=100,y=300)
game1.mainloop()
This is the first time using tkinter on python so actually I stopped after writing this really basic code.
The player can choose seven buttons until player itself clicks the "finish" button. (after click that button, player cannot modify anything.)
At first, I thought if I declare "num" and +=1 on that when the right buttons are clicked, but this trial failed because the player can choose whether one activates or inactivates until until player itself clicks the "finish" button. So I thought that this code needs the way to check the final statements of the buttons.
Is there any ways to use something like "if" statements on tkinter? (if players choose right seven buttons, so it is found that they're activated --> then player wins.)
