len is an intrinsic function that returns the number of elements in a list, the number of characters in a string, or the number of key/value pairs in a map.
Arguments
| Parameter Name | Default Value | Meaning |
|---|---|---|
| self | sequence or map to calculate the length of |
Usage Notes
len may be called either as a global method, passing the sequence or map as an argument; or as a member function (defined on list, string, and map) using dot syntax, with no arguments.
If called with something other than a list, string, or map, len returns null.
Example
x = ["a", "b", "c"]
print x.len // prints: 3
