title: How do I verify specific Cell Value in an Excel Sheet through Pandas Data Frame in Python3.7
body: <p>I have an Excel Sheet having some values, one such cell has Yes/No written in it. Since I have linked the entire file in Python and made a Data Frame of it, how do I verify specific cell values so that only the rows with No value can be printed?</p>
  
  <pre><code>import pandas as pd
  data = pd.read_excel(r'/Volumes/SSD/Project/Raw_Data/Light.xlsx')
  df1 = pd.DataFrame(data)
  df3 = pd.DataFrame(data , columns = ['Person in Room'] ) //Help Needed
  </code></pre>
