I have this section of code that is not working properly. Was wondering whether anyone could understand what is wrong with it?

self.choosen_answers_file = open(os.path.expanduser("~/Desktop/Bradfield/Project/" + str(test_choice) + "/Answers.txt"))
for line in self.choosen_questions_file:
self.new_question = line.replace("\n","")
self.choosen_questions.append(self.new_question)

return(self.choosen_questions[i+1].replace(i+". ",""))
def go_back(self):
frame.destroy()
my_gui = User_Choose_Test(root)
This is the error that outputs:
AttributeError: 'User_Questions' object has no attribute 'question'
The indentation of question and go_back is incorrect. It needs to be un-indented one level.

The scrollbar activates only when the window is rezised, despite reconfiguring the scrollregion everytime a widget(Button in this case) is added.

The last method is the one adding button to the scrollable frame.
After the window is manually resized, no matter if back to its original size, the scrollbar activates and works fine.
I'm trying to make a program that has a button that will open a picture if a variable is in a certain state, and change how the button looks (or maybe show a different picture) if it's not. I have been trying to work through the bugs I've been getting.
This is honestly intermediary code so I can understand how to make what I'm actually trying to do, make a network-enabled GUI for some physical buttons.
I've tried passing blueButton in as a variable, but that didn't work.
import tkinter as tk
weather = "sunny"
class Application(tk.Frame):
def __init__(self, master=None):
super().__init__(master)
self.master = master
self.pack()
self.create_widgets()
def create_widgets(self):
self.blueButton = tk.Button(self, fg = "blue")
self.blueButton["text"] = "I'm Blue"
self.blueButton["command"] = self.change
self.blueButton.pack(anchor="nw")
self.quit = tk.Button(self, text = "QUIT", fg = "red",
command = self.master.destroy)
self.quit.pack(side="bottom")
self.pack(fill = "both", expand = 1)
def change(self):
global weather
if weather == "sunny":
w = tk.Canvas(root, width=400, height=750)
img = tk.PhotoImage(file = "haunter.gif")
w.create_image((200, 200), image = img)
w.pack()
else:
self.blueButton["bitmap"] = "error"
root = tk.Tk()
root.geometry("400x300")
app = Application(master = root)
app.mainloop()
The canvas gets made, but the picture doesn't show up, the "quit" button just moves.
I've also gotten the error "name blueButton is not defined".
You could keep the image as an attribute of your App, put it on a canvas, then show or hide the canvas depending on the weather.

I'm trying to do a Canvas that display a picture in a new window with a pressing a button, actually that is working, but I need the display that show the image in the new windows resize to the new window dimension.
I already tried to manage to get the size to an specific but nothing really worked out for me.
Here is the code:

The Canvas part is this one:
newwin = Toplevel(root)
ncanvas = Canvas(newwin, width=500, height=500)
canvas.pack(fill="both", expand=True)
my_image = PhotoImage(file='label.png')
display = canvas.create_image(850, 50, anchor=NE, image=my_image)
line = canvas.create_line(0, 0, 0, 0)
display.pack()
Thanks in advance,
I am trying to create an application in Python GUI using tkinter. Here is the code I'm using for the GUI part. Whenever I try to access my Entry Widget I get error.
Ex:Sin_put.get() should give me the text in the Entry widget but it gives me an error
AttributeError: 'NoneType' object has no attribute 'get'
I'm relatively new to Python. So if you guys have any suggestions to improve the functionality you're most welcome.

grid() returns None so sin_put will always equal None. Instead of passing the Tkinter ID to grid() you have to store it first if you want to reference it later. Note that for the Buttons, putting it all on one line is fine as you don't use the button's ID later.
sin_put=ttk.Entry(self.scanframe, width = 50) ## stores the return ID from Entry
sin_put.grid(row=0,column=1,padx=5,pady=10) ## don't catch return from grid as it is None

Thank you!
You can either do the designing part in your code or through a QT Designer which ships with PyQt4. and some examples can be found in the path C:\Python26\Lib\site-packages\PyQt4\examples and documentation in the path C:\Python26\Lib\site-packages\PyQt4\doc\html\modules.html if you are using windows. Hope this helps.
