You built a Streamlit app on your laptop. When you run it, the URL shows http://localhost:8501. What does this mean?

• The app is live on the internet

• The app is only accessible on your computer

• The app is running on GitHub

• The app is deployed on Streamlit Cloud

Why do we need a requirements.txt file in the GitHub repository before deploying to Streamlit Cloud?

• To describe the project purpose

• To list Python packages needed for the app

• To add images to the app

• To create the app URL

You want your Streamlit app to be accessible to your classmates with just a link. Which of the following is the correct workflow?

• Run app locally → Share localhost:8501 link
  

• Upload app to GitHub → Deploy on Streamlit Cloud → Share .streamlit.app link
  

• Only share the .py file

• Run streamlit deploy app.py on your terminal

Your Streamlit app uses the google-generativeai library, but you forgot to add it to requirements.txt. What will happen when you deploy?

• The app will still run because Streamlit installs pandas by default

• The app will crash with “ModuleNotFoundError: No module named google-generativeai'”

• GitHub will automatically fix the issue

• The app will show a blank page

You built a Streamlit app that uses OpenAI API. You hardcoded your API key inside app.py and deployed it. After a week, your API key got leaked and misused. What should you have done instead?

• a) Keep using the same key, but restart the app

• b) Store the API key in Streamlit’s Secrets Manager

• c) Save the key in requirements.txt

• d) Add the key to your README.md so collaborators can use it
