   uber_pickups.py.
Open uber_pickups.py in your favorite IDE or text editor, then add these
   lines:
python
   import streamlit as st
   import pandas as pd
   import numpy as np
Every good app has a title, so let's add one:
python
   st.title('Uber pickups in NYC')
Now it's time to run Streamlit from the command line:
bash
   streamlit run uber_pickups.py
Running a Streamlit app is no different than any other Python script. Whenever you need to view the app, you can use this command.
<Tip>
Did you know you can also pass a URL to streamlit run? This is great when combined with Github Gists. For example:
bash
   $ streamlit run https://raw.githubusercontent.com/streamlit/demo-uber-nyc-pickups/master/streamlit_app.py
As usual, the app should automatically open in a new tab in your
   browser.
