Classes¶
Relationship among Classes¶
There are some more APIs that extend the Python built-in function issubclass().
- calcpy.ispropersubclass(*args)¶
Returns True if a argument is a proper subclass of the follow-up argument.
- Parameters:
*args (type | tuple[type] | UnionType) – Classes to check
- Returns:
True if all arguments are proper subclasses of the follow-up arguments
- Return type:
bool
Examples
>>> class A: pass >>> class B(A): pass >>> class C(B): pass >>> class D(A): pass >>> ispropersubclass() True >>> ispropersubclass(object) True >>> ispropersubclass(A, object) True >>> ispropersubclass(C, B, A, object) True >>> ispropersubclass(D, C) False >>> ispropersubclass(A, A) False
- calcpy.ispropersuperclass(*args)¶
Returns True if a argument is a proper superclasses of the follow-up argument.
- Parameters:
*args (type | tuple[type] | UnionType) – Classes to check
- Returns:
True if all arguments are proper superclasses of the follow-up arguments
- Return type:
bool
Examples
>>> class A: pass >>> class B(A): pass >>> class C(B): pass >>> class D(A): pass >>> ispropersuperclass() True >>> ispropersuperclass(A) True >>> ispropersuperclass(object, A) True >>> ispropersuperclass(object, A, B, C) True >>> ispropersuperclass(D, C) False >>> ispropersuperclass(A, A) False
- calcpy.issubclass_(*args)¶
Returns True if a argument is a subclass of the follow-up argument.
- Parameters:
*args (type | tuple[type] | UnionType) – Classes to check
- Returns:
True if all arguments are subclasses of the follow-up arguments
- Return type:
bool
Examples
>>> class A: pass >>> class B(A): pass >>> class C(B): pass >>> class D(A): pass >>> issubclass_() True >>> issubclass_(object) True >>> issubclass_(A, object) True >>> issubclass_(C, B, A, object) True >>> issubclass_(D, C) False >>> issubclass_(A, A) True
- calcpy.issuperclass(*args)¶
Returns True if a argument is a superclasses of the follow-up argument.
- Parameters:
*args (type | tuple[type] | UnionType) – Classes to check
- Returns:
True if all arguments are superclasses of the follow-up arguments
- Return type:
bool
Examples
>>> class A: pass >>> class B(A): pass >>> class C(B): pass >>> class D(A): pass >>> issuperclass() True >>> issuperclass(A) True >>> issuperclass(A, B) True >>> issuperclass(object, A, B, C) True >>> issuperclass(D, C) False >>> issuperclass(A, A) True
