How can I simplify this code in python? : <p>The task is to get all the multiples of 3 below 100, and then add them together.</p>

<pre><code>num1 = 0
l = []
while num1 &lt; 100:
    num1 = num1 + 3
    l.append(num1)
# I used this to delete the last element in the list which is 102,
del l[-1]
print l
# sum of all the numbers in l
b = sum(l)
print b
</code></pre>
