4.5 Types in Python ¶
A big difference between Python and all other Common Lisp compilers
is the approach to type checking and amount of knowledge about types:
- Python treats type declarations much differently that other
Lisp compilers do. Python doesn’t blindly believe type
declarations; it considers them assertions about the program that
should be checked.
- Python also has a tremendously greater knowledge of the
Common Lisp type system than other compilers. Support is incomplete
only for the
not, and and satisfies types.
