How do I create a list with numbers between two values?

Question

How do I create a list of numbers between two values? For example, a list between 11 and 16: ``` [11, 12, 13, 14, 15, 16] ```

Accepted Answer

Use `range`. In Python 2, it returns a list directly:

```
>>> range(11, 17)
[11, 12, 13, 14, 15, 16]
```

In Python 3, `range` is an iterator. To convert it to a list:

```
>>> list(range(11, 17))
[11, 12, 13, 14, 15, 16]
```

Note: The second number in `range(start, stop)` is exclusive. So, `stop = 16+1 = 17`.

To increment by steps of `0.5`, consider using numpy's `arange()` and `.tolist()`:

```
>>> import numpy as np
>>> np.arange(11, 17, 0.5).tolist()

[11.0, 11.5, 12.0, 12.5, 13.0, 13.5,
 14.0, 14.5, 15.0, 15.5, 16.0, 16.5]
```
