title: Replace Cell with value using positional location of cell
body: <p>I have the following sample dataframe below: </p>
  
  <pre><code>ID Text  Value
  A  yes      1
  C  no       1
  </code></pre>
  
  <p>I want to replace the 1 value associated with ID 'C' in the second row with 0.  Traditional ways of replacement that I found online (using .replace) would replace both 1s with 0.  </p>
  
  <p>Below is my desired data set: </p>
  
  <pre><code>ID Text  Value
  A  yes      1
  C  no       0
  </code></pre>
