QUESTION
In Python I'm attempting to create a login page that draws stored data from a Google Sheet for use in Streamlit Authenticator. Streamlit Authenticator authenticates logins by accessing a list container with usernames, passwords, and screen names, as below:
...ANSWER
Answered 2022-Mar-31 at 17:38This is because your username is a list of lists, not a list of strings.
All you need to do is extract the string from the inner list.

ANSWER
Answered 2022-Mar-29 at 10:58You need to use st.download_button
For streamlit > 1.0.0
Display a download button widget.
This is useful when you would like to provide a way for your users to download a file directly from your app.
Note that the data to be downloaded is stored in-memory while the user is connected, so it's a good idea to keep file sizes under a couple hundred megabytes to conserve memory.
A working example can be found here

QUESTION
The goal is to have a streamlit selectbox show a list of pairs coming from the symbol column from the database.
...ANSWER
Answered 2022-Feb-17 at 21:42You have to pass a sequence to a selectbox and each element of that sequence will be shown as a possible element to select. I assume what you are passing is pair = 'BNBBTC'. This means every character becomes one value you could choose. However, what you have to pass to your select box would be
choices = ['ETHBTC', 'LTCBTC', 'BNBBTC'].
As fetchall returns a list of tuples, you can get that as
options = [row[0] for row in cursor.fetchall()] and finally do
st.sidebar.selectbox('Select symbol', options)

QUESTION
I have a streamlit app with sidebar, which consists of a radio button with 2 values: A & B. Both A & B uses st.file_uploadeer() to upload videos to the app. However, when I switch between A & B, the uploaded videos get lost due to page reload. How can I retain the uploaded video unless the user specifically changes the uploaded file? I think it can be done using session states or on_change() callback of the st.file_uploader() function, but I'm not able to figure out how to do it.

QUESTION
I am trying to have an app that loops through a directory (folder and sub) searching for multiple extensions or keywords and outputs the list in a dynamic frame but the code (or returns Zero if nothing found).
Current code fails both when multiple extensions (or keywords) are inputted or fails by grouping multiple results in a single row of the frame.
I need help in debugging my code posted below.
Thank you
...ANSWER
Answered 2022-Jan-15 at 21:44There are some problems in your code:
When getting the extension using
st.text_inputthe returned value is a string not a list of extension. In order to solve this just ask the user to enter the extension seperated with a comma and split the string to get a list of extensions.
