In the following example, we could have just started with ana arraylist of arrayslists, but following the Python example, we process the .data string into a table. ▼Langur has series() and pseries() functions, which generate arrays. These are not limited to integers for start, stop, or increment values. The pseries() function never returns a descending series (returns empty array instead).
You don't always have to convert a range to a series explicitly. Since 0.6.15, the functions map(), fold(), foldfrom(), and zip() accept ranges in place of arrays.

{{works with|langur|0.10}}
Langur 0.7.0 changed the implicit exception variable from .err to _err, and 0.7.1 allows you to map to multiple functions.
Prior to 0.10, multi-variable declaration/assignment would use parentheses around the variable names (.start, .stop, .inc, .comment).
