# partition_sequence_by_ratio_of_weights¶

`sequencetools.``partition_sequence_by_ratio_of_weights`(sequence, weights)

Partitions sequence by ratio of weights.

```>>> sequencetools.partition_sequence_by_ratio_of_weights(
...     [1] * 10, [1, 1, 1])
[[1, 1, 1], [1, 1, 1, 1], [1, 1, 1]]
```
```>>> sequencetools.partition_sequence_by_ratio_of_weights(
...     [1] * 10, [1, 1, 1, 1])
[[1, 1, 1], [1, 1], [1, 1, 1], [1, 1]]
```
```>>> sequencetools.partition_sequence_by_ratio_of_weights(
...     [1] * 10, [2, 2, 3])
[[1, 1, 1], [1, 1, 1], [1, 1, 1, 1]]
```
```>>> sequencetools.partition_sequence_by_ratio_of_weights(
...     [1] * 10, [3, 2, 2])
[[1, 1, 1, 1], [1, 1, 1], [1, 1, 1]]
```
```>>> sequencetools.partition_sequence_by_ratio_of_weights(
...     [1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2], [1, 1])
[[1, 1, 1, 1, 1, 1, 2, 2], [2, 2, 2, 2]]
```
```>>> sequencetools.partition_sequence_by_ratio_of_weights(
...     [1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2], [1, 1, 1])
[[1, 1, 1, 1, 1, 1], [2, 2, 2], [2, 2, 2]]
```

Weights of parts of returned list equal weights_ratio proportions with some rounding magic.

Returns list of lists.
