QUESTION
I use Spyder ide from Anaconda, I just play around with python and try to make the message encode/decode. I get many error from installing the library tkinter and base64. Eventually it runs but have to change to pip install tk/pybase64 instead. And after some trouble, there is new error that I completely don't know how to fix. Resources on the internet don't help me much.
ERROR: cannot import name 'messagebox' from 'tk'
...ANSWER
Answered 2022-Jan-14 at 17:01You don't need to install tkinter or base64 separately at all, they're both built-in. (If Tkinter support hasn't been built in to your Python installation, you will need to rebuild Python with Tkinter support, you can't just install it separately.)
- If you have indeed done
pip install tk, then you will have installed this package that is unrelated totkinter. You'll want to uninstall it. - Similarly, you don't need
pybase64to do base64 operations. Best uninstall it too. - Thirdly, make sure your script isn't called
tk.pyitself. - Finally, as mentioned above, the module is
tkinter, nottk. It's just common to doimport tkinter as tkfor brevity.- Also, using
*imports is generally not a good idea; you'll find your namespace polluted with all sorts of symbols you won't need or know where they're from.

QUESTION
I've heard of people making their own software products and selling it. Sadly, I don't know anybody of such calibre personally. I want to know where could I learn such software design principles and architectures (not for a personal project like taught in the plethora of YouTube videos that exist, but real world application with concurrent user handling and scalability). It would be helpful if someone who knows these things could point me to the right resources. Thank you. [Please only mention resources that you are personally sure of.]
...ANSWER
Answered 2021-Dec-29 at 12:36This may be an unhelpful answer, but this is exactly what people go to university to learn - moving from a basic understanding of personal techniques to a broader more professional understanding of techniques used in industry. (source: studied computing science at university)
Otherwise, just keep working on small projects and you'll learn about it as you go. It can be a daunting task to create something on the scale of Facebook yourself without the expertise, but modern day Facebook wasn't created by one person, and they didn't have all the expertise when they started. You learn either by being taught, or by starting at the start and facing lessons as you encounter them and by learning how to deal with them in the future.
QUESTION
I am trying to create a Kindle dictionary that can be used for offline lookup. I already have the words and their inflections, but turning this into a working dictionary is difficult.
There is some documentation about this provided by Amazon. It basically says that you should:
- Create an XHTML file with their special markup specifying all inflections etc.
- Turn it into an epub
- Open it with Kindle Previewer
- Export it with Kindle Previewer to MOBI
So I created a large XHTML file (23 MB or so) according to the Amazon specifications and opened it in Kindle Previewer, and it looked fine. However, Kindle Previewer does not let you export XHTML files to MOBI. They want you to create an intermediate epub file.
I tried using Pandoc to do the conversion, which did not work because it stripped out all the specific HTML tags and only left in paragraphs. Then I tried using calibre. The normal XHTML -> epub conversion failed because the XHTML file was too large, according to an error message. Calibre suggests to turn on the "heuristic mode" if you run into this error, which I tried, but which did not finish running after hours of runtime.
Then I attempted to create the epub file myself, using a sample file taken from this tutorial. I discovered that this is not trivial, and a check using epubcheck revealed many hard-to-understand errors in my generated file. The generation of the epub file is also a bit complicated by the fact that you probably need to split the XHTML files into many smaller files, which should maybe be 250 kb in size, because e-readers tend to struggle with parsing larger files.
So I thought there should maybe be an easier way to do this, or maybe a library that helps doing this. Maybe it would even be a good idea to output the words + inflections into some other easier dictionary format and then convert it to a MOBI using an existing library and leaving out the XHTML generation completely. Currently I am using Python, but I'd also use other languages if it is necessary. What could I try?
Edit: To add to the things I have tried: there is an apparently closed source script here that unfortunately doesn't support inflections, so does not work. And there are instructions here that advise converting the file to PRC using Mobipocket Creator and then opening it with Kindle Previewer. The problem with this approach is that Kindle Previewer throws the error:
Kindle Previewer does not support this file, which has either been created using an older version of KindleGen or a third party application. We recommend using EPUB or DOCX format directly for previewing and publishing your book on Kindle.
There are also more detailed instructions for Mobipocket Creator here, which tell you to directly move the generated .prc file onto the kindle. I tried that but it is not being recognized as a dictionary.

I am new at programming and I am doing some experiment with this login screen. I want to create some "User" and "Password" combination that can close the project when I click the button "Enter". This should destroy the whole database in the future, but I think thats more like a pro-programmer issue.
For now it kinda works, but it doesn't close the project.
Any idea whats wrong? (I know it only checks password for now, but I would like to fix the button problem first and then check if user is ok too)
...ANSWER
Answered 2021-Aug-22 at 02:54You aren't calling quit function so, It isn't working for you. But Just use root.quit() or root.destroy() should also work.
And you're doing command= I am not sure why but just root.quit() will work, you don't have to do command=root.quit().
Learn more from here to know about .quit() and .destroy().
root.quit()causes mainloop to exit. Callingroot.destroy()will destroy all the widgets and exit mainloop

QUESTION
I currently have a problem where I can't get tkinter to display text in one of its .Text modules because it happens in a function that ends in terminating the whole tkinter window. The idea is to have some final output with operation results appearing in the window for 5 seconds, and then have it shut down. The issue is, tkinter seems to be rigged to only ever let the ".insert(xy)" commands through when the whole function has worked itself out, which in this case means it can't do it. Simplified example code for window:
...ANSWER
Answered 2021-May-18 at 06:31First you don't need to use thread to run menu_outStrsDisplay() if it is not a time-consuming task.
Second you should not called time.sleep(5). Use .after(5000, ...) to call a function (is it tk_on_close()?) after 5 seconds which calls master.destroy() and ws.close():

QUESTION
Browse Button in Right Hand side Panel is being separated when resizing the window. I want the whole thing to stay together and resizing equally.
...ANSWER
Answered 2021-May-05 at 07:04There are four things you need to change:
- don't double-import tkinter. It's enough to import * from it.
- configure the second column of the rightPane to extend when you resize the window.
- Put the button at the western side (W) of the second column by adding
sticky=Wto the.grid()method. - Glue the Entry widget to the Eastern and Western side of column 1. So, it will get wider when this column extends.
With the following code, it works.
You can also use the .colmnconfigure() and .rowconfigure() method on frame widgets to specify how the other pane extends and how the app resizes vertically.

...ANSWER
Answered 2021-Apr-01 at 09:56The problem here is that I am trying to write a library.
I solved the problem by explicitly initialising the resources.
Find the generated CPP file for the resources. In my case it was resources.cpp.
Identify the name of the initialisation and cleanup functions. In my case they are:
int qInitResources_configmgr();
int qCleanupResources_configmgr();
Somewhere suitable, such as in the CPP file for your library's main class, locally declare these two functions.
Call the two functions in the appropriate place. E.g. main class constructor and destructor respectively.
