title: Pandas min() of selected row and columns
body: <p>I am trying to create a column which contains only the minimum of the one row and a few columns, for example:</p>
  
  <pre><code>    A0      A1      A2      B0      B1      B2      C0      C1
  0   0.84    0.47    0.55    0.46    0.76    0.42    0.24    0.75
  1   0.43    0.47    0.93    0.39    0.58    0.83    0.35    0.39
  2   0.12    0.17    0.35    0.00    0.19    0.22    0.93    0.73

  <p>Here I am trying to create a column which contains the minimum for each row of columns B0, B1, B2.</p>
  
  <p>The output would look like this:</p>
  
  <pre><code>    A0      A1      A2      B0      B1      B2      C0      C1      Minimum
  0   0.84    0.47    0.55    0.46    0.76    0.42    0.24    0.75    0.42
  1   0.43    0.47    0.93    0.39    0.58    0.83    0.35    0.39    0.39
  2   0.12    0.17    0.35    0.00    0.19    0.22    0.93    0.73    0.00
  3   0.95    0.56    0.84    0.74    0.52    0.51    0.28    0.03    0.51
  4   0.73    0.19    0.88    0.51    0.73    0.69    0.74    0.61    0.51
  5   0.18    0.46    0.62    0.84    0.68    0.17    0.02    0.53    0.17
  6   0.38    0.55    0.80    0.87    0.01    0.88    0.56    0.72    0.01
  </code></pre>
  
  <p>Here is part of the code, but it is not doing what I want it to do:</p>
  
  <pre><code>for i in range(0,2):
      df['Minimum'] = df.loc[0,'B'+str(i)].min()
  </code></pre>
