title: How to delete \xa0 symbol from all dataframe in pandas?
body: <p>I have a data frame with the 2011 census (Chile) information. In some columns names and some variable values, I have \xa0 symbol and is trouble to call some parts of data frames. My code is the following:</p>
  
  <pre class="lang-py prettyprint-override"><code>import numpy as numpy                    
  import pandas as pd                      
  import matplotlib.pyplot as plt 
  import seaborn as sn
  #READ AND SAVE EACH DATA SET IN A DATA FRAME
  data_2011 = pd.read_csv("2011.csv")
  #SHOW FIRST 5 ROWS
  print(data_2011.head())
  </code></pre>
  
  <p>Doing this got the following output:

  <p>This far, everything is right, but when I want to see the column names using:</p>
  
  <pre class="lang-py prettyprint-override"><code>print("ATRIBUTOS DATOS CENSO 2011",list(data_2011))
  </code></pre>
  
  <p>I got the following ouput:

  <p>How can I fix this? Thanks in advance</p>
