from tkinter import *
window = Tk()
window.title('Pomodoro timer')
window.config(padx=100, pady=50)
canvas = Canvas(width=200, height=224)
tomato_img = PhotoImage(file="C:/vscode/tomato.png")
canvas.create_image(102, 112, image=tomato_img)
Canvas.create_text(102, 112, text='00:00')
canvas.pack()
window.mainloop()
This is the code that I'm working on
when I'm trying to add two integers for x and y co-ordinates to the Canvas.create_text function, it gives me this error
Traceback (most recent call last):
File "C:\pycharm and thonny\pythonProject1\main.py", line 26, in <module>

Alrighty so this is the error I get:
AttributeError: 'DES' object has no attribute 'summary_output'
So this is what I am trying to do.
When I am on this frame, I am creating a text variable that is then sent to a set class.
class upload_csv(Frame):
def __init__(self, master):
self.master = master
self.frame = tk.Frame(self.master, width=250, height=160, bg='white')
self.upload_csv_btn = Button(
self.frame,
text="Add Data Source",
fg="DodgerBlue4",
font=("Graph Type", 15),
height=1, width=20,
borderwidth=2,
relief="groove",
command=self.upload)
self.upload_csv_btn.place(x=10, y=10)
self.frame.pack()
def upload(self):
global text
self.xvalues = []
self.yvalues = []
self.xyvalues = []
self.header = []
filename = filedialog.askopenfilename()
if len(filename) != 0:
print('Selected:', filename)
with open(filename) as file:
csvreader = csv.reader(file)
self.header.append(next(csvreader))
for row in csvreader:
if len(row) == 3:
self.xvalues.append(int(row[0]))
self.yvalues.append(int(row[1]))
self.xyvalues.append(int(row[2]))
text = (
self.header[0][0]+ ": " + str(self.xvalues).replace('[','').replace(']','') +
"\n\n" + self.header[0][1] + ": " + str(self.yvalues).replace('[','').replace(']','') +
"\n\n" + self.header[0][2] + ": " + str(self.xyvalues).replace('[','').replace(']',''))
elif len(row) == 2:
self.xvalues.append(row[0])
self.yvalues.append(row[1])
text = (
self.header[0][0] + ": " + str(self.xvalues).replace('[','').replace(']','') +
"\n\n" + self.header[0][1] + ": " + str(self.yvalues).replace('[','').replace(']',''))
# -------------------------------------------------------------------------
s = Set(text)
s.set_summary()
#-----------------------------------------------------------------------
Using the upload class, I am sending the variable by calling the set class, and calling the set_summary method. With this set class, I am setting the string as a an object item, that is then send to my DES class. I want this item to be set on a tk textbox element as a summary. I receive the text fine in the DES class, but I get the following error when trying to modify the summary element.
The error I get:

def main():

root = tk.Tk()
# app = DES(root)
# app = DES.createFrame(root)
s = DES("")
s.createFrame(root)
root.mainloop()
if __name__ == '__main__':

Edit:
So after trying the answer I got the following error, all I did was add the suggestion:

So I remove the matplot graph and got this error:
So maybe the graph is interfering? Im not sure, I need the graph.
The summary_output in DES class, will be defined in the
createFrame method.
You first instatiated from the DES class in the Set.set_summary()
method and then called the set_summary_text() method, which it uses
the summary_output. That's not correct, since the summary_output has not been defined, yet.
You should first, call the createFrame() method to define the
summary_output attribute and then call the set_summary_text() to
use summary_output.
Do something like this, in the Set class:
class Set:
def __init__ (self, summary):
self.summary = summary
def set_summary(self):
global root
print(self.summary)
s = DES(self.summary)
s.createFrame(root)
s.set_summary_text()
Or do whatever you think it's best for you, but you should define the summary_output first, and then print or use it.
Im writing a Sudoku solver UI in Kivy.
I wanted to add a button, which upon being pressed, solves the Grid. The function works, although when I assign it to a button as the on_press function, it somehow runs before the button is pressed. I've tried everything. I get an Assertion Error. When I just use the solve function, it works. Not with the button, though.
Thank you for helping.
This is the __init__ function:
class SudokuGrid(GridLayout):
def __init__(self, **kwargs):
super(SudokuGrid, self).__init__(**kwargs)
self.grid = [[8,7,0, 0,0,0, 0,0,0],
[0,0,0, 9,0,0, 0,0,4],
[0,2,0, 7,0,0, 1,0,5],
[0,0,9, 6,0,0, 0,3,0],
[0,0,0, 0,0,0, 0,0,9],
[0,0,6, 5,4,0, 0,0,0],
[6,9,0, 0,0,0, 7,0,0],
[2,0,0, 0,0,7, 4,0,0],
[0,0,0, 3,0,0, 0,1,0]]
self.add_widget(Button(on_press=self.solve()))
self.cols = 3
self.rows = 4
self.load_grid()
And this my solve function:
def solve(self):
for x in range(9):
for y in range(9):
if self.grid[y][x] == 0:
for n in range(1,10):
if self.possible(y,x,n):
self.grid[y][x] = n
self.solve()
self.grid[y][x] = 0
return
self.load_grid()
print(np.matrix(self.grid))
I know that the function is run, because before the App terminates, I get the output of the solved Grid.
This is the Traceback:

Okay so i figured it out. Erik said in his comment:
Try on_press=self.solve in stead of on_press=self.solve()
which worked, although I got another Error. I had one too many positional arguments for solve(). I fixed it by defining my method as:
def solve(self, *args)
Everything works now.
I am writing a code for banking system using python and Tkinter. When I run the program I encounter a few errors. Could someone please help me to figure this out. I have done research about it, but can't find a solution to the problem.

The first, parent argument for any Widget creation call must be a widget. In
l1=Label(win3, ...
you passed the win3 function, which does not have a tk attribute.
For the future, please read about MCVEs.
