My A-level project is an alarm system I have built using Tkinter that calculates the nearby traffic and changes your alarm time depending on how much the traffic will slow down or increase your journey.
I have calculated all the times I need, however, now I face the problem of having to constantly poll the current time to check it against my own, but this stops my tkinter functions from running. I am now fearing I should have used a different object orientated language.
How can I run these functions at the same time?
My code is below (I'm sure it is very inefficient).

I just start learning tkinter python for knapsack program. When I try to calculate, it doesn't do anything. And I am getting this error:

I have been trying to figure out a way to modify the label to print element 1 to 4 in a line and repeat. I have attached a picture to hopefully clarify what I am trying to accomplish.
My goal is to make the results look like the following

1 a 2 b 3 c 4 d
my_entries = []
#prints the result
def something():
entry_list =''
index = 0
for entries in my_entries:
index+=1
print(entries.get() + ' ' +str(index))
entry_list = entry_list + str(index) + ' ' + str(entries.get()) + '\n'
if index == 4:
index = 0
my_label.config(text=entry_list)
#prints the element
print('\n'+my_entries[1].get())
def get_value():
my_entries.clear()
value = vialEntry.get()
try:
#print(int(value))
return int(value)
except ValueError:
return None
#this function will create the inputs for the vials elements
def make_entry():
num = get_value()
print(num)

tk.Label(master, text = "Element: "+str(y+1)).grid(row=y+2, column=0, pady=5)
user_entery.grid(row=y+2, column=x+1, pady=0, padx=5)
my_entries.append(user_entery)
#end of make_entry function
my_button = Button(master, text="Click me", command=something)
my_button.grid(row=23, column=0, pady=20)

my_label = Label(master, text='')

You added \n after each index/value pair. You need to add \n after 4 index/value pairs instead:
def something():
entry_list =''
index = 0
for entries in my_entries:
index+=1
print(entries.get() + ' ' + str(index))
entry_list += str(index) + ' ' + str(entries.get())
if index == 4:
index = 0
entry_list += '\n'
else:
entry_list += ' '
my_label.config(text=entry_list)
#prints the element
print('\n'+my_entries[1].get())
Note that the for loop can be simplified as below:
def something_():
entry_list = ''
for i, entry in enumerate(my_entries):
entry_list += f'{i%4+1} {entry.get()}' + ('\n' if i%4 == 3 else ' ')
# or one-liner
#entry_list = ''.join(f'{i%4+1} {entry.get()}' + ('\n' if i%4 == 3 else ' ') for i,entry in enumerate(my_entries))
my_label.config(text=entry_list)

I have a Python program that gets information from a database; in this case, we're making hotel reservations. My issue is that if I use checkboxes and select multiple rooms--only the first in the list shows up. I believe the error to be a counting error of sorts that resides in my checkDetails method.
It would appear, then when trying to get the value of the checkbox, it only works for the first checkbox in the list. To be perfectly honest, I'm not 100% sure how to describe the issue. In lieu of words, I've uploaded four gifs showing the issue.
GOOD: Selecting the first two works fine. Selecting the first item alone works as well. No matter what, the first item always works.
BAD_1:Selecting the first item and another item (any item except the second) only displays the first item regardless.
BAD_2:Selecting any two items that don't involve the first item, results in neither item being displayed.
BAD_3:Selecting any single item that isn't the first item results in it not being displayed.

Definitely one problem is that you're creating more than one instance of tk.Tk(). Tkinter isn't designed to work that way, and it will yield problems similar to what you're seeing.
If you need additional windows, you must create instances of tk.Toplevel.
Another problem is this loop:
for data in self.data:
if self.vars[new_count].get() == 1:
for i in range(5):
Label(self.makeRes, text=data[i]).grid(
row=self.count + new_count, column=i)
new_count += 1
There is a fundamental flaw in the logic. Even though you loop over the data, you keep checking self.vars[new_count]. So, even though you eventually land on data item 3, 4, 5, etc, you keep checking self.vars[0] over and over and over. Once you find one checked item, you now keep looking at self.vars[1] even though you may now be on data item number 3, 4, 5, etc.
One simple fix is to make sure you're iterating over the variables the same as you are iterating over the data values:
for var, data in zip(self.vars, self.data):
if var.get() == 1:
for i in range(5):
Label(self.makeRes, text=str(data[i]) + "?").grid(
row=self.count + new_count, column=i)
new_count += 1
The above assumes there is a 1:1 relationship between the items in self.vars and the items in self.data. It's hard to tell if that's a valid assumption or not.
