title: writing expression in python: multiply string to int
body: <p>I have two DataFrames: one has string and the other has int. I am trying to multiply these two to generate  an algebraic expression:</p>
  <pre><code>df1=pd.DataFrame([1,2,3])
  df2=pd.DataFrame([&quot;x&quot;,&quot;y&quot;,&quot;z&quot;])
  </code></pre>
  <p><strong>Expected Output:</strong> <a href="https://i.stack.imgur.com/feAlj.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/feAlj.png" alt="enter image description here" /></a></p>
  <p>How to generate the expression with two different data types?</p>
