builtins – builtin functions and exceptions

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

For more information about built-ins, see the following CPython documentation:

• Builtin CPython Functions

• Builtin CPython Exceptions

• Builtin CPython Constants

Note

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

Functions and types

abs()

all()

any()

bin()

class bool

class bytearray

class bytes

See CPython documentation: bytes.

callable()

chr()

hasattr()

hash()

hex()

id()

input()

class int

classmethod from_bytes(bytes, byteorder)

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

to_bytes(size, byteorder)

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

isinstance()
