title: Select everything but a list of columns from pandas dataframe
body: <p>Is it possible to select the negation of a given list from pandas dataframe?. For instance, say I have the following dataframe </p>
  
  <pre><code>T1_V2  T1_V3 T1_V4 T1_V5 T1_V6 T1_V7 T1_V8
  1     15      3      2     N     B     N         
  4     16     14      5     H     B     N            
  1     10     10      5     N     K     N  
  </code></pre>
  
  <p>and I want to get out all columns but column T1_V6. I would normally do that this way: </p>
  
  <pre><code>df = df[["T1_V2","T1_V3","T1_V4","T1_V5","T1_V7","T1_V8"]]
  </code></pre>
  
  <p>My question is on whether there is a way to this the other way around, something like this </p>
  
  <pre><code>df = df[!["T1_V6"]]
  </code></pre>
