You are a life saver. I have been looking everywhere for a solution to have the uploaded files 'disappear' after submission. Just wrapping it in a st.form and calling the upload_file function did the trick. Thanks again!

Do you know how to print streamlit data frame tables to pdf file? If you do, can you make a comprehensive tutorial on that? Including printing a long table automatically into multiple pages, adjusting table to fit in page both horizontally and vertically etc?

Hi Andrej, Thanks for the great video! I'm a bit late to the pack, but it's now I need to get into the topic. Where can I find the .py file youre showing in the video?

How to solve this error
streamlitapiexception: set_page_config() can only be called once per app page, and must be called as the first streamlit command in your script.

Hi Andrej, I have tried file upload in azure based web app which is running on single instance. I am getting 403 error when I browse the file. Can you please suggest is there any solution for this. I have gone through docs but the suggestion was to disable XSRF protection which is not acceptable in our organizational setup
