Ask for e-mail before using a certain tool

Using Streamlit
1

Hello everybody!

I’m developing a simple application for a colleague, which might reduce the size of a dataframe and reduce size of pictures. I was looking for a way to ask for an e-mail before someone uploads a file (i’m using st.file_uploader) and store it.

Does anyone knows a way to do that?

def show_contact_form():

if user send contact form == True:
         def upload_file_function():
