Access to Function Call Frames

Syntax

sys.parent(n)

Description

sys.parent provides access to the environments of function calls which enclose the call to it. This is useful for achieving dynamic scoping effects, and is reserved for use by true language wizards.

See Also

eval, function.

Examples

ls(sys.parent(1)) # equivalent to ls() ls(sys.parent(2)) # lists variables in the enclosing call
