title: Pandas / How to convert scientific notation stored as strings into float?
body: <p>I have a list with values stored as strings. Some of the values are stored with scientific notation and others are floats. I tried to cast them using .astype(float) but It didn't work. Any idea on how to deal with this? </p>
  
  <p>My goal is to get the column as float.</p>
  
  <pre><code>df['Colum1] = ['5,4e-05','3,35e-05','0,0001125','0,0001335']
  </code></pre>
