How to create class instance inside that class method?
I want to create class instance inside itself. I tried to it by this way:
class matrix:
(...)
def det(self):
(...)
m = self(sz-1, sz-1)
(...)
(...)
but I got error:
m = self(sz-1, sz-1)
AttributeError: matrix instance has no
__call__
method
So, I tried to do it by this way:
class matrix:
(...)
def det(self):
开发者_JAVA百科 (...)
m = matrix(sz-1, sz-1)
(...)
(...)
and I got another error:
m = matrix(sz-1, sz-1)
NameError: global name 'matrix' is not defined
Of course matrix is not global class. I have no idea how to solve this problem.
m = self.__class__(sz-1, sz-1)
or
m = type(self)(sz-1, sz-1)
