title: Store the numpy array in csv or excel
body: <p>I have a numpy array data as given below:</p>
  
  <pre><code>array([array([ 90.48600884,  97.36925515,  99.90243902, ...,  77.08908407,
         119.06976744, 107.22513089]),
         array([79.27741935, 87.77142857, 87.14893617, ..., 59.36231884,
         97.52380952, 87.39687055])], dtype=object).
  </code></pre>
  
  <p>I want to store this data into a .csv or .excel file. When I am using the usual approach like 
  np.savetxt('test.csv',hr,delimiter =',',fmt = '%s'), it is saving the data in the same way as displayed above means I am not able to access the middle number. Is there any way to store the given numpy array in excel or in csv file so that I can access all the numbers?.</p>
