title: 'float' object has no attribute 'split'
body: <p>I have a pandas data-frame with a column with float numbers. I tried to split each item in a column by dot '.'. Then I want to add first items to second items. I don't know why this sample code is not working.  </p>
  
  <pre><code>data= 
  0     28.47000
  1     28.45000
  2     28.16000
  3     28.29000
  4     28.38000
  5     28.49000
  6     28.21000
  7     29.03000
  8     29.11000
  9     28.11000
  
  new_array = []
  df = list(data)
  for i in np.arange(len(data)):
      df1 = df[i].split('.')
      df2 = df1[0]+df[1]/60
      new_array=np.append(new_array,df2)
  </code></pre>
