py_bool {reticulate}

Python Truthiness

Description

Equivalent to bool(x) in Python, or ⁠not not x⁠.

Usage

py_bool(x)

Arguments

x

A python object.

Details

If the Python object defines a ⁠__bool__⁠ method, then that is invoked. Otherwise, if the object defines a ⁠__len__⁠ method, then TRUE is returned if the length is nonzero. If neither ⁠__len__⁠ nor ⁠__bool__⁠ are defined, then the Python object is considered TRUE.

Value

An R scalar logical: TRUE or FALSE. If x is a null pointer or Python is not initialized, FALSE is returned.
