title: Writing something to print sig figs and errors for an array
body: <p>Alright for my class I take an array of data and do some computations to find the error associated with each element in the array. How do I have a print statement show both the number and its error with the correct sig figs?</p>
  <p>I have tried</p>
  <pre><code>print('The count rate and its error is %.2f +- %.2f' %Array,Array_err)
  </code></pre>
  <p>but I get the error that I cannot convert the array to a python scalar. Is there a way to do have this all in the same print statement?</p>
