My aim is to take the data from 3 different CSV file and create a nested dictionary, I realize my error, but I fail to fix it.
Shall I create 3 different methods for each file to iterate the data and then create the nested dictionary, or it is something else that I have to do?
Code:
class STproject:
def __init__(self,app): #1
self.mlb=LabelFrame(app, text='Movie Recommendation Engine')
self.mlb.grid()
self.lframe3=LabelFrame(self.mlb,text="Movies/Users",background='purple')
self.lframe3.grid(row=0,column=1)
self.framebutton=Frame(self.mlb,background='pink',height=50,width=50)
self.framebutton.grid(row=0,column=0)
self.buttonsnlabels()
def buttonsnlabels(self):
self.ratingbutton=Button(self.framebutton,text='Upload movies',command=lambda :self.file1())
self.ratingbutton.grid()
self.ratingbutton=Button(self.framebutton,text='Upload ratings',command=lambda :self.file2())
self.ratingbutton.grid()
self.ratingbutton=Button(self.framebutton,text='Upload links',command=lambda :self.file3())
self.ratingbutton.grid()
def file1(self):
umovies=tkFileDialog.askopenfilename()
f=open(umovies)
self.csv_file1 = csv.reader(f)
self.dictionary()
def file2(self):
uratings=tkFileDialog.askopenfilename()
f=open(uratings)
self.csv_file2 = csv.reader(f)
self.dictionary()
def file3(self):
links=tkFileDialog.askopenfilename()
f=open(links)
self.csv_file3 = csv.reader(f)
self.dictionary()
def dictionary(self):
for line1,line2,line3 in zip(self.csv_file1,self.csv_file2,self.csv_file3):
dict={}
dict[line1]={[line2]:[line3]}
root=Tk()
root.title()
application=STproject(root)
root.mainloop()
and this is the error given:

I would suggest to first store the selected results at a place, and process them later by another button. In the below sample i'm using StringVar to store the file paths.

Note that I also moved the location and the name of the dict in your original code. In your code, not other it shadows the built in method dict, it also overwrites itself during each iteration of the for loop, which i think would not be what you looking for.

I'm trying to update a label based on a button press that does some calculations first, but I'm getting an error I don't understand.
Background: This method was working fine in previous iterations. I have not changed the code. But I did make some changes to the class by adding a controller to the initial instantiation of the ShelfDownloader class, which these methods belong to. To clarify ShelfDownloader is only called once from a different module.
Description: On the initial call of this class, it displays the self.total_books_label correctly, but when I switch shelves it chokes. UPDATE: It seems I am passing a string, but I in the comments I posted what I tried and I still don't understand the error. See the second error:
Question: Since that's probably not the problem, I'm thinking one of my calls is missing something. Any suggestions please?
I removed the widget formatting for this question. I included these bits of code to help with the Error message.
class ShelfDownloader(ctk.CTkFrame):
def __init__(self, parent, controller):
ctk.CTkFrame.__init__(self, parent)
self.parent = parent
self.controller = controller
...
def shelf_option_callback(self, parent, *args):
if not self.downloader:
sys.exit()
shelf_choice = [s for s in SHELF_METADATA if self.shelf_choice_var.get() in s['shelf_name']][0]
for k, v in shelf_choice.items():
self.downloader_dict[k] = v
updated_dict = self.downloader.update_shelf(**self.downloader_dict)
for k, v in updated_dict.items():
self.downloader_dict[k] = v
self.display_total_books_and_pages(parent)
def draw_top_panel(self):
parent = self.top_frame
LL1 = ctk.CTkLabel(parent, text="Choose shelf to download:")
# LL1.pack()
shelf_opt_menu = ctk.CTkOptionMenu(master=parent, width=170, variable=self.shelf_choice_var,
values=self.shelf_list,
command= lambda: self.shelf_option_callback(parent)
## ^^^^^^^^^^^^^^^^^^^^^^^^^^^
## This is my problem spot. Tried adding
## command=self.shelf_option_callback(parent)
## but different error.
shelf_opt_menu.pack()
def display_total_books_and_pages(self, parent):
if hasattr(self, 'total_books_label'):
self.total_books_label.destroy()
## GUI feedback info, partially a debugging tool
_books, _pages = (self.downloader_dict['total_book_count'], self.downloader_dict['total_page_count'])
self.display_text.set(f"Shelf has {_books} books, retrieving {_pages} pages.")
logger.debug(f"{self.display_text.get()}")
logger.debug(f"display_total_books_and_pages: {type(self.display_text)}")
self.total_books_label = ctk.CTkLabel(master=parent, width=180,
text=f"{self.display_text.get()}")
self.total_books_label.pack()
My debugging returns correct and expected output after I switch the shelf, ie shelf_opt_menu:
2022-12-12 12:05:22,612, gui_download, 183: Shelf has 1624 books, retrieving 17 pages.
2022-12-12 12:05:22,612, gui_download, 184: display_total_books_and_pages: <class 'tkinter.StringVar'>
I get an error message that I'm passing a string in the code above. UPDATE: I trimmed the full error out since I confirmed that's what is happening with logger.debug(f"{type(parent)}")

TypeError: ShelfDownloader.draw_top_panel.<locals>.<lambda>() takes 0 positional arguments but 1 was given
I wasn't utilizing the StringVar, self.display_text, properly. I fixed it. Here's how: I set a trace in the callback shelf_option_callback. I call self.set_display_text from the trace to change the value of self.display_text. I moved the Label creation to draw_top_frame(self) so that it always resides in the desired position and added the option textvariable=self.display_text to the Label. This did the trick.
The Label rewrites new values in the same spot when the shelf_opt_menu OptionMenu changes.

This is another window which will be started by the main one.
It shows some buttons on the left and some labels and textboxes on the right.
Whenever a button on the left has been pushed the text of the labels should be changed.
That's the problem: When I push a button I get this error and the text won't be changed:
Exception in Tkinter callback

I don't really understand why this gives me an error so I'd like to ask you.
This code is being started from the main window with the code:
program.app.create(arrSettings) #arrSettings is an array in which some colors for the design are
Thanks in advance.
Do not declare and pack in the same line
Return of this peice of code is None
Label(win_0, text="Option0").pack()
whereas, this returns an object of Label class
Label(win_0, text="Option0")
so use:-
lbl_0 = Label(win_0, text="Option0")
lbl_0.pack()
instead of
lbl_0 = Label(win_0, text="Option0").pack()
Also use self object as argument to functions. Check that the variables are in scope wherever you are using it.
This should help you get through this error...
I have only done a little work with Tkinter and I enjoy using it but as with any type programing it takes time to learn. I am trying to create a simple To do list that will eventually be saved on a file. But i can't get the button in line 17 to be removed and the on the next line be replace in a different position.
from tkinter import *
import time
root = Tk()
root.geometry("300x300")
root.title("Programs")
global TDrow
TDrow = 2
def tdTaskAdd():
global TDrow
global tdEnter
TDrow = int(TDrow+1)
s = tdEntry.get()
label = Label(ToDoFrame,text=s).grid(row=TDrow,column=1)
tdEntry.grid(row=TDrow+1,column=1)
tdEnter.grid_remove()
tdEnter = Button(ToDoFrame,text="AddTask",command=tdTaskAdd).grid(row=TDrow+2,column=1)
ToDoFrame = Frame()
ToDoFrame.place(x=0,y=10)
tdTitle = Label(ToDoFrame,text="To Do List:").grid(row=TDrow-1,column=1)
tdEntry= Entry(ToDoFrame)
tdEntry.grid(row=TDrow+1,column=1)
tdEntry.insert(0, "Enter a new task")
global tdEnter
tdEnter = Button(ToDoFrame,text="Add Task",command=tdTaskAdd).grid(row=TDrow+2,column=1)
mainloop()
I keep getting an error when running this saying that:
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Python33\lib\tkinter\__init__.py", line 1475, in __call__
return self.func(*args)
File "C:\Users\Eddy\Desktop\pythonStartup.py", line 17, in tdTaskAdd
tdEnter.grid_remove()
AttributeError: 'NoneType' object has no attribute 'grid_remove'
The problem is this line:
tdEnter = Button(ToDoFrame,text="Add Task",command=tdTaskAdd).grid(row=TDrow+2,column=1)
This way, tdEnter is not the Button, but the return value of grid, i.e. None.
Try this instead:
tdEnter = Button(ToDoFrame,text="Add Task",command=tdTaskAdd)
tdEnter.grid(row=TDrow+2,column=1)
Same for label and when you create a new button in your tdAddTask function.
BTW, no need to add a new button each time, just call it's grid method to repositon it.
Okay so here is my problem. I am trying to create a very open ended user friendly Gui out of Tkinter. In short I made a button a function STAGE that creates a Listbox that has choose-able indexes. Then I can press the button SUBMIT that will print the selected keys.
BUT if I press ADD STAGE to make another listbox of the same value I CANNOT go back and edit or retrieve the selected values of the old listbox.
I understand that this is because of the listbox will have the same name so.....

If someone could help me with this that would be great.
You need list of listbox to keep all lists from all stages.
Now in listbox you have only list from last created stage.
You will have to use lines like this (in different places)
self.all_listboxes = []
#---
self.all_listboxes.append( listbox )
#---
for one_list in self.all_listboxes:
for x in one_list.curselection():
BTW: use self.listbox (in __init__) in place of global listbox.
The same with i0 and Tech_option.
We use class and self to not use global
I have a problem in class inheritance in Python; maybe it's not related to inheritance, but I have no other idea. I'm working with selenium web-driver. Here's the code I use:
from selenium import webdriver
class UIInterface(object):
def __init__(self):
self.driver = webdriver.Ie()
self.driver.get('URL')
def parentMethod(self, itemClassName = ''):
allElements = self.getAllElements()
return [el for el in allElements if el.get_attribute('type') == 'checkbox']
def getAllElements(self):
return self.driver.find_elements_by_tag_name('input')
class InterfaceChild(UIInterface):
def __init__(self):
super(InterfaceChild, self).__init__()
def childMethod(self):
returnedList = self.parentMethod(itemClassName = 'SomeClassName')
for item in returnedList:
print item.get_attribute('innerHTML')
This code gives me an error for line returnedList = self.parentMethod(itemClassName = 'SomeClassName'); the error description is this:
(<type 'exceptions.AttributeError'>, AttributeError("'InterfaceChild' object has no attribute 'self'",), <traceback object at 0x000000000418E5C8>)
I thought it might be related to inheritance, so I tried to put parentMethod and getAllElements in the class InterfaceChild; same exception raised. Any idea about this??
EDIT 1:
This is the main method for making instance of classes:
if __name__ == '__main__':
ieInterface = InterfaceChild()
ieInterface.childMethod()
This is the complete stack-trace:

I installed selenium with pip under Python 2.7 and changed the code to use Chrome driver[1] instead and changed the checker to make sure there would be some input tags being found. full code below. I'm running the code on Mac OS X. it works just fine.
So I guess the issue here is not the code. (Windows is not a friend of Python, perhaps :).
from selenium import webdriver
class UIInterface(object):
def __init__(self):
self.driver = webdriver.Chrome()
self.driver.get('http://duckduckgo.com')
def parentMethod(self, itemClassName = ''):
allElements = self.getAllElements()
result = [el for el in allElements]
print('===', result)
return result
def getAllElements(self):
return self.driver.find_elements_by_tag_name('input')
class InterfaceChild(UIInterface):
def __init__(self):
super(InterfaceChild, self).__init__()
def childMethod(self):
returnedList = self.parentMethod(itemClassName = 'SomeClassName')
for item in returnedList:
print item.get_attribute('innerHTML')
if __name__ == '__main__':
ieInterface = InterfaceChild()
ieInterface.childMethod()
The output looks like:
