c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	82 Python is an interpreted, interactive, object-oriented programming
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	83 language that combines remarkable power with very clear syntax.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	84 For an introduction to programming in Python you are referred to the
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	85 Python Tutorial.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	86 The Python Library Reference documents built-in and standard types,
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	87 constants, functions and modules.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	88 Finally, the Python Reference Manual describes the syntax and
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	89 semantics of the core language in (perhaps too) much detail.
