I am trying to create a program that reads lines from a file and puts them into a tkinter window. At the moment my code is this:
def read_notifications():
#def update():
# window.config(text=str(random.random()))
# window.after(1000, update)
aaa = 1
while True:
re = open("Y:/System Info/notifications.txt", "r")
rf = re.read()
rh = rf.count("\n")
re.close()
lines = [line.rstrip('\n') for line in open("Y:/System Info/notifications.txt")]
rk = -1
while True:
aaa = aaa + 2
rk = rk + 1
#print(lines[rk])
rl = rk + 1
ya = lines[rk].split("#")
yb = str(tomrt)
if ya[1] == yb:
yc = "Tommorow"
else:
if ya[1] == "0":
yc = "Monday"
if ya[1] == "1":
yc = "Tuesday"
if ya[1] == "2":
yc = "Wednesday"
if ya[1] == "3":
yc = "Thursday"
if ya[1] == "4":
yc = "Friday"
if ya[1] == "5":
yc = "Saturday"
if ya[1] == "6":
yc = "Sunday"
c = 650
window = tk.Tk()
#back = tk.Frame(width=700, height=c)
#back.pack()
window.title("Notifications")
window.iconbitmap("1235.ico")
#Subject
lbl = tk.Label(window, text=ya[0])
lbl.config(font=("Courier", 18))
lbl.grid(column=0, row=0)
#lbl.pack(side=tk.LEFT,)
#Day
lbl = tk.Label(window, text=" " + yc)
lbl.config(font=("Courier", 16))
lbl.grid(column=2, row=0)
#Type
lbl = tk.Label(window, text=ya[2])
lbl.config(font=("Courier", 16))
lbl.grid(column=4, row=0)
#Descripion
lbl = tk.Label(window, text=ya[4])
lbl.config(font=("Courier", 16))
lbl.grid(column=6, row=0)
#lbl.pack(side=tk.LEFT)
#window.after(1000, update)
if rl == rh:
print("hello")
break
if aaa > 2:
time.sleep(4)
window.destroy()
else:
window.mainloop()
I am not sure why this doesn't work properly. I am trying to make it so the tkinter window will update itself every 4 seconds, as another program is making changes to the notifications.txt file and I want the tkinter windows to update accordingly.
You code is a bit hard to re-work but here is a working example of how one can monitor a file.
Say I have a file that contains 4 lines and we call this file my_file:
1 test
2 testing
3 more testing
4 test again
All we want to do is update the labels ever 4 seconds so we can use the after() method to keep us going.
Take a look at this below code.
import tkinter as tk
window = tk.Tk()
window.title("Notifications")
file_to_monitor = "./my_file.txt"
def read_notifications():
with open(file_to_monitor, "r") as f:
x = f.read()
string_list = x.split("\n")
lbl1.config(text=string_list[0])
lbl2.config(text=string_list[1])
lbl3.config(text=string_list[2])
lbl4.config(text=string_list[3])
window.after(4000, read_notifications)
lbl1 = tk.Label(window, text="")
lbl1.grid(column=0, row=0, stick="w")
lbl2 = tk.Label(window, text="")
lbl2.grid(column=0, row=1, stick="w")
lbl3 = tk.Label(window, text="")
lbl3.grid(column=0, row=2, stick="w")
lbl4 = tk.Label(window, text="")
lbl4.grid(column=0, row=3, stick="w")
read_notifications()
window.mainloop()
What we start out with on the first read:
Then after I have made a change to the file and saved from my notepad:

I am creating a code that allows the user to enter 4 values (a, b, c, and d) for the equation (ax^3+bx^2+cx+d), then the program will output the graph on a window (I am using Tkinter). however, the code for some reason doesn't work.
To explain a bit my code in the input_check process I am outputting a button on a window with a blank box for the input. when the input is entered the program will check if it is the same as 3 (I will be adding more equations after (therefore it will check which equation the user wants), then it should asks for the values of a, b, c, and d, however after than it gives an error.
My code is:
from tkinter import *

the error that I keep getting is:
ValueError: x and y must have same first dimension, but have shapes (10,) and (1, 10)
I tried to search online for any information but I didn't find anything usefull.
(I found some solutions that use canvas but I have no idea on how to use it).
Can anyone help me please?
New to python so this is probably a dumb question...
I want to say that if text1.get() == "1" then x = 0 and if text2.get() = "2" then y = 8. Then I want a button that adds x and y.
from tkinter import *
new = Tk()
new.title("Lockdown?")
new.geometry("700x400")
text3=Entry(new, width = "60")
text3.place(rely=0.15)
if text3.get() == "":
label9 = Label(new, text="required field", fg="red")
label9.place(rely=0.17)
elif text3.get() == "1":
x = "0"
elif text3.get() == "2":
x = "1"
elif text3.get() == "10":
x = "9"
else:
label10 = Label(new, text = "Please use a number ranging from 1-10")
text4=Entry(new, width = "60")
text4.place(rely=0.26)
if text4.get() == "":
label11 = Label(new, text="Required Field", fg = "red")
label11.place(rely=0.19)
elif text4.get() == "7":
y = "3"
elif text4.get() == "8":
y = "2"
elif text4.get() == "9":
y = "1"
elif text4.get() == "10":
y = "0"
else:
label11 = Label(new, text = "Please use a number ranging from 1-10")
def cmd3():
label15 = Label(new, text = x + y)
label15.place(rely=0.8)
btn3 = Button(new, text = "Submit Answers", command = cmd3, font=("Arial Bold", 25), bg = "white", fg = "black")
btn3.place(rely=0.71)
new.mainloop()
GUI frameworks (tkinter, PyQt, wxPython, etc., and in other languages) don't work like function input(). Entry doesn't wait for your data - it only inform mainloop what it has to display in window. And mainloop starts all - it displays window, etc. If you want to get value from Entry then you should do it in function assigned to Button.
My version with other changes
I use pack() instead of place() because it is simpler to organize widgets.
I create all labels at start (with empty text) and later I replace text in labels.
import tkinter as tk # PEP8: `import *` is not preferred
# --- functions ---
def cmd3():
# default value at start
x = None
y = None
# remove previous text
label1['text'] = ""
label2['text'] = ""
text = text1.get()
if text == "":
label1['text'] = "required field"
elif text == "1":
x = 0
elif text == "2":
x = 1
elif text == "10":
x = 9
else:
label1['text'] = "Please use a number ranging from 1-10"
text = text2.get()
if text == "":
label2['text'] = "required field"
elif text == "7":
y = 3
elif text == "8":
y = 2
elif text == "9":
y = 1
elif text == "10":
y = 0
else:
label2['text'] = "Please use a number ranging from 1-10"
print(x, y)
# it can't be `if x and y:` because `0` will gives `False`
if (x is not None) and (y is not None):
label_result['text'] = str(x + y)
# --- main ---
new = tk.Tk()
# empty at start
label1 = tk.Label(new, text="", fg="red")
label1.pack()
text1 = tk.Entry(new, width="60") # PEP8: arguments without spaces around `=`
text1.pack()
# empty at start
label2 = tk.Label(new, text="", fg="red")
label2.pack()
text2 = tk.Entry(new, width="60")
text2.pack()
btn3 = tk.Button(new, text="Submit Answers", command=cmd3)
btn3.pack()
# empty at start
label_result = tk.Label(new, text="", fg="green")
label_result.pack()
new.mainloop()
It got executed once but I add some features and now it doesn't work anymore...
I'm a beginner at python and this is my first project. I'd like to create a game (which works perfectly in the console) but I have some troubles to put it with tkinter

The calls to get

What is wrong with this program? Every time I run it the first math problem is show before I push start. Also the answer is always the first math problem, it never changes. Also there should not be a math problem above the timer. Thanks, Scott

Your problem is with how you're calling the Questions() method. You only ask for the answer once with
answer = Questions()
and you do this before you press start (which is why it shows up before you hit start)
To fix it you could use code like this:
from Tkinter import*

number2 = random.randrange(1,50)
answer = number1 + number2
