title: Using user input variables in PandaSQL
body: <p>I'm trying to use pandaSQL on a dataframe that I have and I'm wondering if there's a way to use variables or if there's another way to do it. What I'm trying to do is setting user input as a variable and then trying to use that in the SQL statement. I want to display every instance that a shape when input. I'm trying stuff along the lines of:</p>
  
  <pre><code>variable1 = input("Enter shape here: ")
  print pysqldf("SELECT imageNum FROM df WHERE shape1 = variable1 ")
  </code></pre>
  
  <p>but so far no luck. Everything else is working fine, I'm just running into trouble when introducing variables. Is this possible in pandaSQL and if not, what workarounds could I use?</p>
