title: Create dynamic worksheet variable
body: <p>I have a list with following data:</p>
  
  <pre><code>month = [ "Jan", "Feb", "Mar", "Apr" ]
  </code></pre>
  
  <p>Each month's data is stored in JSON like:</p>
  
  <pre><code>[{"Master" : [
          {
             "month" : "Jan",
             "Expense" : "50",
             "Income" : "100",
             "Emp" : "1"
          },
          {
             "month" : "Jan",
             "Expense" : "500",
             "Income" : "1000",
             "Emp" : "2"
          },
          {
             "month" : "Feb",
             "Expense" : "50",
             "Income" : "100",
             "Emp" : "1"
          },
          {
             "month" : "Feb",
             "Expense" : "500",
             "Income" : "1000",
             "Emp" : "2"
          },
          {
             "month" : "Mar",
             "Expense" : "50",
             "Income" : "100",
             "Emp" : "2"
          },
          {
             "month" : "Apr",
             "Expense" : "50",
             "Income" : "100",
             "Emp" : "1"
          }
       ]
  }]
  </code></pre>
  
  <p>Depending on the value of <code>month</code>, I need to write all the content of each month's data to separate sheets with names "Jan", "Feb", "Mar", "Apr" etc using a <code>for loop</code>, something like:</p>
  
  <pre><code>for i in range(len(month)):
      worksheet[i] = workbook.add_worksheet(month[i])
  </code></pre>
  
  <p>The content in the list <code>month</code> is subject to change and hence the dynamic variable allocation required.  </p>
  
  <p>Is this possible?</p>
