All builtin functions and exceptions are described here. They are also available via builtins module.

Not all of these functions and types are turned on in all CircuitPython ports, for space reasons.

.. function:: abs()

.. function:: all()

.. function:: any()

.. function:: bin()

|see_cpython| bytes.

.. function:: callable()

.. function:: chr()

.. function:: classmethod()

.. function:: compile()

.. function:: delattr(obj, name)

   The argument *name* should be a string, and this function deletes the named
   attribute from the object given by *obj*.

.. function:: dir()

.. function:: divmod()

.. function:: enumerate()

.. function:: eval()

.. function:: exec()

.. function:: filter()

frozenset() is not enabled on non-Express CircuitPython boards.

.. function:: getattr()

.. function:: globals()

.. function:: hasattr()

.. function:: hash()

.. function:: hex()

.. function:: id()

.. function:: input()

.. classmethod:: from_bytes(bytes, byteorder)

   In CircuitPython, ``byteorder`` parameter must be positional (this is
   compatible with CPython).

.. method:: to_bytes(size, byteorder)

   In CircuitPython, ``byteorder`` parameter must be positional (this is
   compatible with CPython).

.. function:: isinstance()

.. function:: issubclass()

.. function:: iter()

.. function:: len()

.. function:: locals()

.. function:: map()

.. function:: max()

.. function:: min()

.. function:: next()

.. function:: oct()

.. function:: open()

.. function:: ord()

.. function:: pow()

.. function:: print()

.. function:: property()

.. function:: range()

.. function:: repr()

.. function:: reversed()

reversed() is not enabled on non-Express CircuitPython boards.

.. function:: round()

.. function:: setattr()

The slice builtin is the type that slice objects have.

.. function:: sorted()

.. function:: staticmethod()

.. function:: sum()

.. function:: super()

.. function:: type()

.. function:: zip()

.. exception:: AssertionError

.. exception:: AttributeError

.. exception:: Exception

.. exception:: ImportError

.. exception:: IndexError

.. exception:: KeyboardInterrupt

.. exception:: KeyError

.. exception:: MemoryError

.. exception:: NameError

.. exception:: NotImplementedError

.. exception:: OSError

.. exception:: RuntimeError

.. exception:: ReloadException

   `ReloadException` is used internally to deal with soft restarts.

.. exception:: StopIteration

.. exception:: SyntaxError

.. exception:: SystemExit

    |see_cpython| :py:class:`cpython:SystemExit`.

.. exception:: TypeError

    |see_cpython| :py:class:`cpython:TypeError`.

.. exception:: ValueError

.. exception:: ZeroDivisionError
