I want to decrease the size of an entry in tkinter python. ive already asked about label but i havent used fyi
the code:
from tkinter import *
from tkinter import messagebox
top = Tk()
top.title("Hello wold")
top.geometry("300x300")
ei = StringVar()
ei1 = StringVar()
def karma():
try:
ee = ei.get()
ee1 = ei1.get()
ez = int(ee) + int(ee1)
return messagebox.showinfo('message', f'{ee} + {ee1} = {ez}')
except ValueError:
return messagebox.showinfo('message', f'ERROR')
name = Label(top,text="1st no. : ").place(x = 20,y = 50)
e = Entry(top,textvariable=ei).place(x = 100, y = 50)
name1 = Label(top,text="2nd no. : ").place(x = 20,y = 100)
e1 = Entry(top,textvariable=ei1).place(x = 100, y = 100)
b = Button(top, text="Click here", command=karma).place(x = 20,y = 150)
top.mainloop()
you may use the font option in Entry to adjust the size.
Here is an example (to change it to 8pts)
import tkFont
helv8 = tkFont.Font(family='Helvetica', size=8)
e = Entry(top, font = helv8, textvariable=ei).place(x = 100, y = 50)
this is my first time trying subclasses, so I don't know if I did it right, but when I run this i get a few error
File "C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.9_3.9.1520.0_x64__qbz5n2kfra8p0\lib\tkinter\__init__.py", line 1892, in __call__
return self.func(*args)
TypeError: cart_order() missing 1 required positional argument: 'self'
And
File "C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.9_3.9.1520.0_x64__qbz5n2kfra8p0\lib\tkinter\__init__.py", line 1892, in __call__
return self.func(*args)
File "C:\Users\GGPC\OneDrive\Desktop\trying subclasses.py", line 337, in order_menu
t = final_cart(parent, Test)
NameError: name 'parent' is not defined.
and when i used command=t.calculate_order i got the error
self.button_checkout = Button(self.my_frame2, command = t.cart_order)
NameError: name 't' is not defined
Trying to run the sub class "final_cart" when the buttons are clicked that are in the main class. I did a lot of testing and trialing and could not find a solution, so your help is appreciated.
Thank you.

Essentially you have subclassed Goode_brothers so the two classes act as one when you instantiate final_cart.
Firstly the line: class final_cart(Goode_brothers): means that final_cart inherits from Goode_brothers.
Secondly the line: FoodSystem = final_cart(root) instantiates final_cart making the two classes act as a single class. This means that any method which calls self.anothermethod() has access to the union of all the methods from the two classes.
i am making a sign up page and im trying to store the email the user entered to a text file but it doesnt seem to work it stores ".!toplevel.!entrywrite" instead of user input. i am new to this python and tkinter so i dont really know what to do, the code is a little bit long sorry about that.
Any help will be appreciated. Thank you

Using var = StringVar() to set option textvariable - var when initialize Entry, and get content of Entry by var.get().
example Code
from tkinter import *
def on_click():
print(entry_text.get())
root = Tk()
font = ("Courier New", 32)
entry_text = StringVar()
entry = Entry(root, textvariable=entry_text, font=font)
entry.place(x=0, y=0)
button = Button(root, text='Check', command=on_click, font= font)
button.place(x=0, y=64)
root.mainloop()
Following statement will get value None for self.email
self.email = Entry(parent).place(x = 340, y = 180)
should be
self.email = Entry(parent)
self.email.place(x = 340, y = 180)
I have all the gui configurations and all that stuff in my main.py and my algorithms to draw bubble sort and merge sort in another .py file. I'm trying to write the print functions into my canvas but I'm not sure how to do it, can anyone help? I tried using a ListBox() but it messes up the main canvas for some reason.

tamData = [i / max(data) for i in data]
for i, height in enumerate(tamData):

and this is my bubbleSort.py

print(("El numero " + str(data[j]) + " es mayor que " + str(data[j+1])))
data[j],data[j+1] = data[j+1], data[j]
print(("Intercambiando de lugar " + str(data[j]) + " con " + str(data[j+1])))
dibujar(data,
[
'green'
if x == j or x == j+1
else 'red' for x in range(len(data))
]
)
time.sleep(1)
dibujar(data, ['green' for x in range(len(data))])
You can just pass in c2 to the function on the other file. So first define the parameter:
def bubbleSort(data, dibujar, cnv):
cnv.create_text(100,100,text='Trial Text')
....
Now each time you call this function, pass on c2 to it.
if menu.get() == 'BUBBLE SORT':
bubbleSort(data, dibujar, c2)
I did notice that you are using dynamic points for calculation, if so, make those points global, inside the function, then pass those onto the function by creating more parameter, while keeping in mind that the points have to defined before the function is called.
Having taken a class on C and Assembly, I decided I wanted to learn python. This is my first attempt with it so please excuse any abuse of notation.
The following is the portion of my GUI I have created to control a grow cycle. I am having an issue with the use IntVar. I have created a countdown to the end-of-cycle (see countdown method). I have tried including the self.remaining label within Countdown, it does show the countdown but the label showing the countdown does not destroy with the cancel button and time_state label at end-of-cycle. With the self.remaining label put in the init using IntVar, it shows the initial countdown in days,hours, mins,secs but stays with that initial value and does not update as countdown is repeated. Shouldn't using IntVar this way update the day_val, hour_val, min_val, and sec_val in the self.remaining label?

After reviewing your code I have made some changes to how you are formatting your strings and how you are apply strings to your labels.
Your class def was not working for me so I rewrote it with a standard method I use to create a tkinter class.
I don't believe you can have both a text = "string' and a textvariable = StringVar() at the same time. So I have formatted the data into your string var.
The way you had it set up it would not work for a few reason. You cant use multiple IntVar()'s in a textvariable so you need to first combine them into a string variable and then use that as your update method to the label.
I have changed your string concatination removing the + method and using format() instead as this is the correct method currently.
I also added self.string_var.set to your countdown() method so we can keep this updated with the countdown.
Take a look at this code and let me know if you have any question.
