Python is only involved when extract_lineage() analyzes raw SQL
strings or duckplyr frames (or falls back to sqlglot for a dbplyr
pipeline it cannot trace in R); dbplyr, dtplyr, and arrow pipelines
are analyzed by pure-R engines. The sqlglot engine
needs the reticulate package (a Suggests dependency; install it with
install.packages("reticulate")); dplyneage then declares its sqlglot
dependency via reticulate::py_require(), so sqlglot itself is
provisioned automatically the first time it is needed. Use this to
check availability, or to gate code that needs the sqlglot engine
(examples, vignette chunks, Shiny apps). Returns FALSE when
reticulate is not installed. Note that calling it may initialize
Python.
