title: How to overcome the Could not convert String to Float?
body: <p>Hi Everyone I'm Having This Two Columns:</p>
  
  <pre><code>Mi_Meteo['Measurement'] = Mi_Meteo['Measurement'].str.rstrip(' Measure')
  Mi_Meteo['Measurement'].head()
  
  0    0.8
  1    0.6
  2    0.4
  3    0.4
  4      0
  Name: Measurement, dtype: object
  </code></pre>
  
  <p>And:</p>
  
  <pre><code>Mi_Meteo['Sensor_ID'] = Mi_Meteo['Sensor_ID'].str.rstrip(' ID')
  Mi_Meteo['Sensor_ID'].head()
  0    14121
  1    14121
  2    14121
  3    14121
  4    14121
  Name: Sensor_ID, dtype: object
  </code></pre>
  
  <p>So , i tried to convert both of them to float , nut was got an error:</p>
  
  <pre><code>Mi_Meteo['Measurement'] = Mi_Meteo['Measurement'].astype(float)
  
  ValueError: could not convert string to float: 
  </code></pre>
  
  <p>And:</p>
  
  <pre><code>Mi_Meteo['Sensor_ID'] = Mi_Meteo['Sensor_ID'].astype(float)
  
  ValueError: could not convert string to float: 
  </code></pre>
  
  <p>Any Suggestion , would be much appreciated , thank U all.</p>
