title: How to ignore some words in a word cloud in Python?
body: <p>In Python3 and Pandas I have this program to make word cloud from a column:</p>
  
  <pre><code>import pandas as pd
  import numpy as np
  from wordcloud import WordCloud
  import matplotlib.pyplot as plt
  
  autores_atuais = pd.read_csv("deputados_autores_projetos.csv", sep=',',encoding = 'utf-8', converters={'IdAutor': lambda x: str(x), 'IdDocumento': lambda x: str(x), 'CodOriginalidade': lambda x: str(x), 'IdNatureza': lambda x: str(x), 'NroLegislativo': lambda x: str(x)})
  
  autores_atuais.info()
  &lt;class 'pandas.core.frame.DataFrame'&gt;
  Int64Index: 6632 entries, 74057 to 84859
  Data columns (total 10 columns):
  IdAutor             6632 non-null object
  IdDocumento         6632 non-null object
  NomeAutor           6632 non-null object
  AnoLegislativo      6632 non-null object
  CodOriginalidade    5295 non-null object

  Ementa              6632 non-null object
  IdNatureza          6632 non-null object
  NroLegislativo      6632 non-null object
  dtypes: object(10)
  memory usage: 569.9+ KB
  
  
  wordcloud = WordCloud().generate(' '.join(autores_atuais['Ementa']))
  plt.imshow(wordcloud)
  plt.axis("off")
  plt.show()
  </code></pre>
