4.1. Calling Prolog from Python

[ Prev - Up - Next ]

This is done with the engine methods:

.run(<query>): Returns first answer, no backtracking.
.call(<query>): Returns first answer, allows backtracking
.redo(): Backtracks from previous .call().
.calls(<query>): Returns an iterator for use in for-loops

which have are already discussed in the 'Use' section. The query can be a string, an AmziTerm (an Amzi TERM object wrapped in a Python object), or a tuple representing a term, as described in 'Building'.
