# interlace_sequences¶

`sequencetools.``interlace_sequences`(sequences)

Interlaces sequences.

Example 1. Interlaces generators:

```>>> sequences = []
>>> sequences.append(range(100, 103))
>>> sequences.append(range(200, 201))
>>> sequences.append(range(300, 303))
>>> sequences.append(range(400, 408))
>>> sequencetools.interlace_sequences(sequences)
[100, 200, 300, 400, 101, 301, 401, 102, 302, 402, 403, 404, 405, 406, 407]
```

Example 2. Interlaces tuples:

```>>> sequences = []
>>> sequences.append(tuple(range(100, 103)))
>>> sequences.append(tuple(range(200, 201)))
>>> sequences.append(tuple(range(300, 303)))
>>> sequences.append(tuple(range(400, 408)))
>>> sequencetools.interlace_sequences(sequences)
[100, 200, 300, 400, 101, 301, 401, 102, 302, 402, 403, 404, 405, 406, 407]
```

Example 3. Interlaces lists:

```>>> sequences = []
>>> sequences.append(list(range(100, 103)))
>>> sequences.append(list(range(200, 201)))
>>> sequences.append(list(range(300, 303)))
>>> sequences.append(list(range(400, 408)))
>>> sequencetools.interlace_sequences(sequences)
[100, 200, 300, 400, 101, 301, 401, 102, 302, 402, 403, 404, 405, 406, 407]
```

Example 4. Interlaces strings:

```>>> sequences = []
>>> sequences.append('first')
>>> sequences.append('second')
>>> sequencetools.interlace_sequences(sequences)
['f', 's', 'i', 'e', 'r', 'c', 's', 'o', 't', 'n', 'd']
```

Returns list.
