Line no 52, in choose_color function
self.color = askcolor(color=self.color)[1]
it is better to write it in this way,
color = askcolor(color = self.color)[1]
if color != None:
self.color = color
else:
return None
code to completely clear the canvas ?
thank you in advance
and also is there any way to save my "Masterpiece"
Tkinter canvas keep track of every elements is added to it and return an id of each element. You can store the id, to specify which element to delete.
id1= canvas.create_line(0, 0, 100, 100)
And then to delete the element use the following code,
canvas.delete(id1)
And, to delete all the elements just use 'all' as the parameter to delete method,
canvas.delete('all')
Hey @nikhilkumarsingh, how can i save masterpiece so that i can directly use it in another application? is there any way to directly connect this paint with another python file?
Super!

if you plan on saving it as an image grab the rectangle ( could use win32gui.GetWindowRect) and then save it using 'filedialog.asksaveasfilename'
if anyone, like me, is wondering if we can make it anti aliased somehow, here is an interesting approach:
код, чтобы полностью очистить холст?
заранее спасибо,
а также есть ли способ спасти мой "Шедевр"
Found the best repository, everything you need is there, here it is: https://github.com/PVkolos/Paint_Python
You can save the drawing and paint over with white, in general, everything you need
Привет, @nikhilkumarsingh , как я могу сохранить шедевр, чтобы напрямую использовать его в другом приложении? есть ли способ напрямую связать эту краску с другим файлом python?

Thank you @nikhilkumarsingh. I have updated the code a bit. May I upload that code on my git, crediting you for base code?
