Pandas: how to edit values in a column of a .csv file?
<p>I have a .csv file which looks as follows:<a href="http://i.stack.imgur.com/buFdW.png" rel="nofollow">link</a></p>

<p>I want to open this file using pandas and edit the column <strong>Coordinate</strong> by adding a constant value of 756 to each value in it. Finally, I want the changes to be reflected in the .csv file.</p>

<p>How do I do that?</p>

<p>Edit: What I had been doing is as follows (@EdChum):</p>

<pre><code>df = pd.read_csv('C:/TestBook1.csv')
df = df[['Coordinate','Speed']]

Coord = df['Coordinate']
Coord = Coord + 756
</code></pre>

<p>This is where I was going wrong. From here it would have been a messy affair to save changes into the .csv file.</p>
