Python Examples

• To run these examples, you must first set the PYTHONPATH to the atomspace python install directory, after installing atomspace. Tun the following command from your shell,

      export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python3/dist-packages/
  

• From the python prompt, the following should list the opencog python modules

      help('opencog')
  

• The contents of a single module can be viewed by using dir function. For example,

      import opencog.atomspace
      print dir(opencog.atomspace)
  

• You can run the examples from your shell. For example,

      python create_atoms_by_type.py
  

create_atoms_by_type.py, create_atoms_simple.py

Simple examples of how to create atoms in an atomspace. These demonstrate two different ways in which the API can be used; one creates atoms according to their types, the other creates them directly.

stop_go.py

A simple example of a "behavior tree" implemented in the AtomSpace.
