This doesn't match exactly what you asked for, but may match what you meant 
to ask for, and certainly it clearly states what is happening:

>>> [i + delta for i in 1, 2, 3 for delta in 0, 0.1]
[1, 1.1000000000000001, 2, 2.1000000000000001, 3, 3.1000000000000001]

... and you may in fact have meant to ask for this:

>>> [i + delta for i in 1, 2, 3 for delta in 0.0, 0.1]
[1.0, 1.1000000000000001, 2.0, 2.1000000000000001, 3.0, 3.1000000000000001]
