I would like to divide list items inside two lists.

```
a = [[1, 0, 2], [0, 0, 0], [1], [1]]
b = [[5, 6, 4], [6, 6, 6], [3], [3]]
```

How can I divide a by b to obtain this output:

```
c = [[0.2, 0, 0.5], [0, 0, 0], [0.333], [0.333]]
```

Can anyone help me?

Using `itertools.izip`

(Python2.7):

```
import itertools
[[float(aaa) / bbb for (aaa, bbb) in itertools.izip(aa, bb)] \
for (aa, bb) in itertools.izip(a, b)]
```
