title: How do I check if a value is appearing multiple times in the same column in pandas?
body: <pre><code>import numpy as np 
  import pandas as pd
  
  for i and x in df1.total_amount:
  if i in df1['total_amount'] == x in df1['total_amount']:
      print( str(i) + &quot; is repeating&quot;)
  </code></pre>
  <p>This does not return the desired result.</p>
