NETGEAR NAS DUO 2110 setup on WIN11platform
by MikeH May 11, 2024

May 11, 2024

Hi, I have had this NAS for many years it it has worked like a charm on my windowsXP 0S laptop. Recently I purchase a new Asustor laptop running WIn11 and I cannot get it to work on this PC. The device shows as storage device on my home screen and in file explorer with its IP & I can sucesfully ping it. When I try to login with its IP , I receive an error message which says “….this browser (google) has no support for this interface with an error message code Ox0004002” Searching on the web indicates this may be because a communications protocol TLS 1.0 or 1.1 is no longer supported, or advised , on the windows 10/11 platform which the NAS’s software uses. Has anyone else had this issue and is there a solution or work round. I have done a factory reset on the NAS. Thanks MikeH Sent from my iPad

Split Drive Setup
by Mike May 9, 2024

May 9, 2024

Hi, I’m using a new 64bit windows11 platform to install python 3.11.3 which I download from the official Python site. I ran the setup programme on my system pc disk C:\ , but changed the location for the bulk of the python files to an external usb HDD to (P:\python\python_3_11_3) , so as not to use a large amount of space on my system drive & have a portable python facility on the USB HDD. The installation completed without any errors and placed an icon on my pc to launch the python command window , which works. I created a one line test script on the pc (print (“hello python !!”) with a ‘py’ file type label and then double clicked that file but nothing happened .? Can anyone help to solve this problem or indicate other things I need to done, or should have done ? , on my PC or my external HDD MikeH Sent from my iPhone (TalkTalk)

tkinter ttk style
by Phil May 9, 2024

May 9, 2024

I've spent a lot of time reading documentation and tying to adapt examples to set two ttk buttons to different background colours without success. Using the following code both buttons have the same background colour. self.style = ttk.Style() self.style.configure("TButton", background="orange") self.style.configure("TButton.another_button", background="pink") exit_button = ttk.Button(frame, text="Exit", command=self.destroy) exit_button.grid(column=3, row=3, padx=5, pady=5) anothert_button = ttk.Button(frame, etc) I've even resorted to asking my AI friend for help and eventually I got working code that included the following. Although it works almost perfectly (the pink button is smaller than the exit button for some reason) the code seems to be unnecessarily convoluted. self.style.layout( "TButton.another_button", [ ( "Button.focus", { "children": [ ( "Button.padding", {"children": [("Button.label", {"sticky": "nswe"})]}, ) ] }, ) ], ) Again, any tips will be greatly appreciated. -- Regards, Phil

Ideas on making this cleaner?
by Leam Hall May 7, 2024

May 7, 2024

This gets a rough USA grade level report for chapters in a book. There's a lot of "count()" duplication, can it be done in a cleaner fashion? Coding style is Python 3.12 and standard library only; no exceptions. I also run "black -l 79" on everything. :) Full code is at: https://github.com/LeamHall/bookbot class Report: def __init__(self, data, filename): self.filename = filename self.lines = list() for line in data: self.lines.append(line.lower()) self.count_sentences() self.count_words() self.count_syallables() self.grade_report() def count_sentences(self): """Counts the number of sentence ending marks.""" self.sentence_count = 0 for line in self.lines: self.sentence_count += line.count(".") self.sentence_count += line.count("?") self.sentence_count += line.count("!") def count_words(self): """Counts the number of words, ignoring punctuation.""" self.word_count = 0 for line in self.lines: self.word_count += len(line.split()) def count_syallables(self): """Simplistic syllable counter.

Centring an image on a label
by Phil May 7, 2024

May 7, 2024

Spurred on by a recent question about displaying images, I have developed an image viewer that works except I haven't been able to centre the image when the image is less than the width or height of the frame. I have label on a frame. The frame is set to 600 x 600. Images that are wider or higher than 600 are scaled to fit. The frame and label are defined as follows: photo_frame = ttk.Frame( root, height=600, width=600, borderwidth=3, relief="sunken") photo_frame.grid(row=0, column=0, padx=10, pady=10, sticky=tk.NSEW) self.photo_label = ttk.Label(photo_frame) self.photo_label.grid(row=0, column=0, padx=0, pady=0)#sticky=tk.NSEW) root.grid_rowconfigure(0, weight=1) root.grid_columnconfigure(0, weight=1) photo_frame.grid_propagate(False) I have a test image that requires a padx of 63 to be centred and I'm trying to do that as follows: self.photo_label.configure(padx=63) Resetting the padding before the image is displayed has no effect and and neither does resetting the padding after the image is displayed. photo = ImageTk.PhotoImage(image) self.photo_label.config(image=photo) self.photo_label.image = (photo) It appears that the way that I'm trying to centre the image is not the correct method. I had a play with the pack manager but that didn't seem to be the answer either. Is it possible the centre the image without calculating the required padding? Any suggestions will be greatly appreciated. -- Regards, Phil
