body: <p>I am new to spark.</p>
  
  <p>I want to print my spark data frame name on the spark console.
  eg: my data frame name in df1. if I try to print it on the console, its getting printed as below:
  DataFrame[id: int, name: string]</p>
  
  <p>Do we have any built-in function to print the just data frame name? </p>
