init(self, type=0)
(Constructor)

source code

Initialize type of norm

Overrides: object.__init__

call(self, args)
(Call operator)*

source code

Calculate result of norm(arg1,arg2,...)

Parameters:

args (list of float) - list of floats as arguments for norm.

Returns: float

result of norm calulation

Raises:

NormException - any problem in calculation (wrong number of arguments, numerical problems)

checkArgs2(self, args)

source code

Checks args to be 2 float values.

Parameters:

args (list of float?) - list of arguments

Returns: (float,float)

first two args as float values

checkArgsN(self, args)

source code

Checks args to be at least 2 float values.

Parameters:

args (list of float?) - list of arguments

Returns: list of float

arguments as float values

repr(self)
(Representation operator)

source code

Return representation of instance.

Returns: string: representation of instance
Overrides: object.__repr__
