title: Multiply two Pandas dataframes with same shape and same columns names
body: <p>I have two dataframes A, B with NxM shape. I want to multiply both such that each element of A is multiplied with respective element of B. </p>
  
  <pre><code>e.g:
  A,B = input dataframes
  C = final dataframe
  I want C[i][j] = A[i][j]*B[i][j] for i=1..N and j=1..M
  </code></pre>
  
  <p>I searched but couldn't get exactly the solution.</p>
