len

Function

Get size of a String, list/tuple, or dict.

Syntax

len(value, /)

Parameters

Name	Description
`valueString \| list \| tuple \| dict`	Value to measure Required · Positional only No default

Returns

Int — Number of items/characters.

Behavior / side effects

Get size of a String, list/tuple, or dict.

Execution

Blocking: No
Thread safety: Use separate objects per flow
Parallel execution: Yes

Value operations execute in the calling flow without an intentional wait for capture, gesture completion, or user input. Create mutable containers/builders separately in each flow; this is isolation, not a shared-object synchronization guarantee.

Example

name = "CogniTab"
count = len(name)
text(str(count))

Errors / limitations

No additional limitations documented; follow the parameter and behavior contract above.
