title: Add Row to Dataframe With Streamlit
body: <p>I have a data frame with my stock portfolio. I want to be able to add a stock to my portfolio on streamlit. I have text input in my sidebar where I input the Ticker, etc. When I try to add the Ticker at the end of my dataframe, it does not work.</p>
  <pre><code>ticker_add = st.sidebar.text_input(&quot;Ticker&quot;)
  
  df['Ticker'][len(df)+1] = ticker_add
  </code></pre>
  <p>The code <code>[len(df)+1]</code> does not work. When I try to do <code>[len(df)-1]</code>, it works but I want to add it to the end of the dataframe, not replace the last stock. It seems like it can't add a row to the dataframe.</p>
