# Welcome to Streamlit!

Edit `/streamlit_app.py` to customize this app to your heart's desire :heart:.
If you have any questions, checkout our [documentation](https://docs.streamlit.io) and [community
forums](https://discuss.streamlit.io).

In the meantime, below is an example of what you can do with just a few lines of code:
"""

    if city_input: # Only add if the input is not empty
        st.session_state.cities.append(city_input)
        st.success("Expander added!")
    else:
        st.warning("Please enter some content.")
