title: How to recursively upload folder to Azure blob storage with Python
body: <p>I can upload single file to Azure blob storage with Python. But for a folder with multiple folders containing data, is there a way I can try to upload the whole folder with same directory to Azure? 
  <br/></p>
  
  <p>Say I have <br/><br/>
  FOLDERA  <br/>
      ------SUBFOLDERa <br/>
      ----------filea.txt <br/>
      ----------fileb.txt <br/>
      ------SUBFOLDERb <br/>
      ------SUBFOLDERc <br/>
  <br/>
  I want to put this FOLDERA as above structure to Azure. 
  Any hints?</p>
