I am trying to modify some code to work for me.
I have a running application with tkinter and I can update both scores (blue and red) when I am pressing the buttons, but I want to find a way how to do this via keypress ? For example to increase the score for the reds when pressing "r" and increase the score for the blue when pressing "b"
Tried different things from google but without any luck.
Could someone have a look and give me some hints?

You can use keybindings to run the function when a key is pressed
window.bind("b", addblue )
Here are a website and a video explaining them further
https://effbot.org/tkinterbook/tkinter-events-and-bindings.htm
https://www.youtube.com/watch?v=GLnNPjL1U2g
Hi #Veleslav Panov and welcome to Stack Overflow! You can use the .bind()method available in tkinter t achieve this task. For example, imagine that you want to update variable on pressing the Enter or the Return key. Then use this:
def function_name(*args):
variable_name +=1
#say the updation to be done here
name_of_window.bind("<Return>", function_name)
Note: Instead of *args, you can use any variable name, the only thing needed is that there should be at least one variable
You can use us .bind() to bind any key to any function, the only requirment is that the function will have some argument, for example 'event'.
def function(event):
#Do something
window.bind("<Return>", function)
This way, every time the button (in this case Enter) is pressed, the function will be called. In your case you would bind 2 buttons, 'r' and 'b', to 2 functions to add score to each of the sides.
Here is a link with some examples:
https://www.geeksforgeeks.org/python-binding-function-in-tkinter/

I've written a program where the UI displays a button that says "Enter Brewer Info" and once the user clicks that button, it calls the function "option1()" as a callback. The function option1() then calls brewers() function and gets user input to assign the values for num_brewer and brewer which is then returned in that function. The num_brewer and brewer var is then assigned as a global variable in option1() and global brewer_flag is set to 1.
Inside the while loop, it checks to see if brewer_flag is set to 1 and if not, it prints "Please select '1' to enter the brewer information first:". Once the user has entered the brewer info and brewer_flag is set to 1 (in option1 function), it's supposed to display "Brewers Selected: "+str(brewer)+" in the label but even after i enter brewer info and brewer_flag is set to 1, it still prints "Please select '1' to enter the brewer information first:" in the label and doesn't change the label to display the brewer array.
What exactly am i doing wrong?
(Im also aware that my while loop needs to exit by making leave = 1 but I'm doing that later)

Here is a minimal example of how to create a Checkbutton and to attach a boolean variable and event to it:
import tkinter as tk
window = tk.Tk()
# callback for checkbutton
def checkbox_callback():
is_checked = checkbox_var.get()
print(f"The checkbox is selected: " + str(is_checked))
# variable to store the current value of the checkbutton
checkbox_var = tk.BooleanVar()
# checkbutton with text, variable and callback
checkbox = tk.Checkbutton(window, text="Click me", variable=checkbox_var, command=checkbox_callback)
checkbox.pack()
window.mainloop()

It is not crashing without an error, it is raising the following exception : Cannot choose from an empty sequence.
This means that the main_var is empty (you have removed every element from it). You should check for it before trying to remove an element :
def num_generate():
if len(main_var) > 0:
random_num = random.choice(main_var)
num.set(random_num)
print(random_num)
main_var.remove(random_num)

I'm currently working on a project where you scan bar codes and it implements the result into an excel file. I am using tkinter to make my GUI, however, when I try to get the values from a text widget it returns the value ".!frame3.!frame3.!frame.!text". how can I fix this to get the appropriate values?

You are printing the command and not the value of it. Put the command in a variable and then print the variable.
Example: myVar = out_list.get("1.0", "end-1c") and then print(myVar)
I have this code:
def show_hide(a, b, c, d):
if not b[0]["text"]: # check if text's length is 0
b[0].configure(text="{}".format(d[0]), bd=2, bg="white", command=lambda: activate_deactivate(a[0], c[0])) # configure button_1
c[0]["text"] = "Status: {}".format(a[0].get()) # set text for label_1
b[1].configure(text="{}".format(d[1]), bd=2, bg="white", command=lambda: activate_deactivate(a[1], c[1])) # configure button_2
c[1]["text"] = "Status: {}".format(a[1].get()) # set text for label_2
else:
b[0].configure(text="", bd=0, bg="#F0F0F0", command=None) # hide the button_1
c[0]["text"] = "" # hide the label_1
b[1].configure(text="", bd=0, bg="#F0F0F0", command=None) # hide the button_2
c[1]["text"] = "" # hide the label_2
My button which calls this function has this command value:
command=lambda: show_hide([status, status_2], [button, button_2], [label, label_2], ["Perform action #1", "Perform action #2"]))
By using it I can show/hide buttons but rewriting the same thing changing a digit in a few places would be tedious. To fix it I tried using this code instead of the original:
def show_hide(a, b, c, d):
for i in range(0, len(a)): # iterates over indexes of items in a,b,c,d lists (all 4 have same length) and passes them to the if/else statement
if not b[i]["text"]: # check if text length is 0
b[i].configure(text="{}".format(d[i]), bd=2, bg="white", command=lambda: activate_deactivate(a[i], c[i])) # configure buton
c[i]["text"] = "Status: {}".format(a[i].get()) # set label's text
else:
b[i].configure(text="", bd=0, bg="#F0F0F0", command=None) # hide button
c[i]["text"] = "" # hide label
Theoretically, this should work fine and using just 4 lines of code (not counting for/if/else lines) do the same thing as original function which would need 4 lines for EACH status+button+label created. BUT, as a matter of fact, it makes my 2 buttons work totally wrong.
I don't really understand what is wrong with it so I can't fully describe the problem, but you can see for yourself by using the test-script I made and replacing the show_hide function definition with the one using for-loop:

frame_1 = tk.Frame(frame, padx=10)
frame_1.pack(side="left")
frame_2 = tk.Frame(frame, padx=10)
frame_2.pack(side="left")
button = ActionButton(frame_1)
button.grid(row=0, column=0)
label = ActionLabel(frame_1)
label.grid(row=1, column=0)
button_2 = ActionButton(frame_2)
button_2.grid(row=0, column=1)
label_2 = ActionLabel(frame_2)
label_2.grid(row=1, column=1)
next_day = tk.Button(root, text="Next day", bg="white", font="courier 30",
command=lambda: multi(step_forward(status, button, label),
step_forward(status_2, button_2, label_2)))
next_day.pack()
root.mainloop()
I hope there's someone who may know how to fix this and maybe even has an idea about how the function could be changed to perform everything properly.
