ttk | Topological Data Analysis and Visualization - Source Code | Data Visualization library

I am able to use SQLite3 as the database (DB) and get Treeview to display data from the DB. However, I was wondering whether Treeview has any functionality to censor the first few characters in a certain column for all entries?

Here is the lean code:

For educational purpose I am using Python, Tkinter and Sqlite to create small prefabricated sentences, with small language templates like text.insert (tk.END, f "{City_Name} {is a city that owns} {Inhabitants} {inhabitants} {on a surface of} {Surface} "). The result should be (by way of example I remain the parentheses): {Paris} {is a city that owns} {2 229 095} {inhabitants} {on an area of} {105 km²}

The app starts with the selection of the Country in a combobox and then with the selection of the City in the combobox in the next combobox, for example "Paris", which in the database corresponds to City_Name. So the whole app focuses on city selection in the second combobox. So how can I retrieve from the row all the other data (Inhabitants, Name inhabitants, Surface, Language of the database) corresponding to "Paris", in order to automatically display them in the textobox, replacing them when requested?

To replace them when prompted automatically when prompted, I mean the curly brackets in text.insert, i.e. {Inhabitants}, {Surface}, etc.

IMPORTANT: In this way, I don't have to write the code for every single city, but I can write only one code that is valid for all the cities, because they automatically change {City_Name}, {Inhabitants}, {Surface}

P.S: I don't want to focus on a specific city, but obviously when you change the name of the city in the Combobox City, the data also changes (the row of data in the database), taking those corresponding to the selected city.

Can you please help me and show me the part of the code I need? Thank you

I want to divide space equally between three buttons using Grid Layout in Tkinter. And those buttons should occupy the space equally even when the window is resized horizontally.

So I have been trying to build a simple text editor with tkinter but unfortunately when I use the open() function in Python to open a specific file, an error shows up, saying 'TypeError: 'PhotoImage' object is not callable' on line 83. How is this even related to PhotoImage? Could it be possible that this is related to Image.open() ? Here's the code:

I am new to Python. I'm having trouble executing an IF with a function inside. I enclose the code, including the graphic interface in Tkinter. In the same algorithm, I was wrong and i have difficulty in 2 things: write the correct IF conditions, and correctly call the Function inside IF, that is:

Since I already have a code that I am attaching, how can I manipulate the text and do these two things?

1. If I click on Button 1: in the vertical column "Word 1" of the database, is a random/casual word taken from among the various ones and then printed in the multiline textbox?
2. If I click on Button 2: in the vertical column "Word 2" a random/casual word is taken from among the various ones, and also in the vertical column "Word 3" a random/casual word is taken from among the various ones. Then both words are combined/merged and printed in the multiline textbox in this example way (with space): "gggggg ooooooo" or "Hello world".

I'm just starting out with Python. Can you show me the code of the 2 questions I asked, please? Thank you and excuse me

I ran the instructions from this question on stackoverflow. Credo di aver fatto tutto (o quasi) correttamente. I cannot understand what is wrong. No error in console/terminal. The problem is that the Combobox2 remains empty, after selecting the Combobox1.

Why does the combobox2 (City) remain empty, when I select a nation in combobox1 (Nation)? I would like the different names of each city for each selected nation to appear in combobox2 Thank you

I'm starting out with Tkinter in Python. I'm having a hard time doing a simple thing. There are two comboboxes. For example, selecting the text "" Test1 "in the first combobox Category, I would like Hello1", "Hello2", "Hello3" to open in the second combobox Subcategory.

Maybe I wrote the code wrong from the start. I would like to ask you 2 things:

1. Can you help me with my IF problem?

2. I think I haven't written the right code from the first line. Can you give me a system of all the code please? Fortunately it is not long Thank you

So I was messing around with the progressbar in ttk, but I was wondering how to change its length. Not like the numerical value of its length, but the actual visual length of the progressbar.

With other widgets, I would just to 'width=27' or whatever and change it that way, but it doesn't seem to work.

Any ideas? Thank you.
