This comment is redundant with the code and useless:
</font><pre><font size="4" color="blue">
v = 5     # assign 5 to v
</font></pre><font color="black">This comment contains useful information that is not in the code:
</font><pre><font size="4" color="blue">
v = 5     # velocity in meters/second. 
</font></pre><font color="black">Good variable names can reduce the need for comments, but
long names can make complex expressions hard to read, so there is
a tradeoff.</font><br /
