In this video, I will be showing you how to build a Python web application from scratch using Streamlit. I will also show you how to connect your streamlit app to a database. In particular, we will be using a free NoSQL database from deta. I will cover the entire process from start to finish and show you how easy it is to build your own web application. We will also learn how to create an interactive Sankey chart using Plotly. Additionally, I will show some very nifty streamlit tricks. After this video, you will be confident to develop your own web apps.

If I can take the time to say how much I enjoyed this content and such a rich solution to a Streamlit App development . I am self taught now for 7 years and I really seem to identify with your style of coding. Ex. Using different list in settings and looping through to establish your datasets. I just love the way this came together and it was well thought out and delivered. My only concern is what of Deta is Depricated for some reason ? I guess doing a fetchall and storing on a local DB would do the trick using cron job ? Your thoughts are appreciated...

@CodingIsFun 6 ай бұрын

Thank you for watching and for your kind words. I'm glad to hear that you appreciate my coding/teaching style. Regarding your question: Yes, Deta has undergone significant changes in recent months. The product is now called Deta Space (which you can still use for this project, but the steps differ, and you would need to refer to the current documentation). However, as you mentioned, you could also use any other database of your choice. Happy coding! :)

@nikolasandreou9962 Жыл бұрын

Hello, and THANK YOU. Streamlit is now one of my favourite tools thanks to your helpful videos and tutorials. Just one thing though if you could please help, Deta is now upgraded to Space I think and I can't set it up.

I can't manage to make the config.toml file to not break my streamlit app. Whenever I save the file, a new error appears and it is about streamlit not being able to read utf-8 or something. Nothing on the internet has helped me so far. Have you ever faced this kind of problems with themes?

@CodingIsFun Жыл бұрын

Ensure your config.toml is UTF-8 encoded and without special characters. Verify the file syntax and its location in a .streamlit directory at your project root. Also, make sure you're using Streamlit v0.79 or newer, which support themes. If these don't help, sharing your error message can help to pinpoint the issue better.

@@CodingIsFun I just wanted to say a huge thank you for teaching me programming! As a teacher, I was a complete noob until you showed me the ropes a few weeks back. Now, I've got four awesome Streamlit apps that make my job a lot more fun. Let me buy you a coffee to say thanks! And by the way, what's your favorite IDE for coding?

@@arnoldtvisagie Awesome work on making those four Streamlit apps! It's great to hear that I was able to help you along the way. My favourite IDE is definitely VS Code - it's got so many cool features and extensions. Thank you for offering to support me with a coffee ☕! You can do so here: pythonandvba.com/coffee-donation. Keep up the good work. Happy Coding! 🚀

Good tutorial, but too much time is wasted on Deta NoSQL database. Database popularity statistics don't lie. Most Python developers want simple, local SQLite databases to start, then PostgreSQL, MySQL, and other SQL databases. Please redo this tutorial using SQLite. Thank you.

Hey there , Why in the world did you choose that Deta platform to create the database bro, a new user like me even can't find how to get the api key to create a database Worst experience 😞 bro, everything was going fine untill you started with the deta platform.......

Deta has changed after releasing the video... Cheers, Sven ✌️

this deta space is literally the worst ui i have ever seen; its impossible to navigate through the website; i am pissed

I feel you! I'm not a fan of the new UI either. I find myself lost in (Deta) space too 😬

this is great and I followed up until Deta... :( I've spent 30 mins on trying to get a new project setup with no luck

Thanks for watching. Yes, deta cloud changed to deta space. I am also not very happy with that change 😅 Please refer to the deta space documentation: deta.space/docs/en/reference/base/sdk I hope it helps! Happy Coding!

Thank you for your videos. Please could you help me with the following question. After I import a .csv with only two decimals like 1.00 or 333.00, the following lines don't maintain those two decimal. Those decimals become 1.000000 or 333.000000. I would like to have only two decimal. Could you help!? with st.expander("Table"): st.write(category_df.style.background_gradient(cmap="Blues")) csv = category_df.to_csv(index=False).encode('utf-8') st.download_button("Download", data=csv, file_name="file.csv", mime="text/csv", help='Click here to download') with st.expander("Table"): df_selection["month"] = df_selection["date"].dt.month_name() sub_category_Year = pd.pivot_table(data=df_selection, values="amount", index=["name"], columns="month") st.write(sub_category_Year.style.background_gradient(cmap="Blues")) with st.expander("filtered"): st.write(df_selection.iloc[:500, 0:20:1].style.background_gradient(cmap="Blues_r"))

Thank you very much for watching the video and your comment. Your requirements are well noted. Yet, I receive many requests for creating individual solutions. As much as I want to help, I simply do not find the time in my daily schedule to develop & test all the different requests. I hope you can understand. Thank you!
