Your comment is equivalent to this: >>> complex(1+2.0j) (1+2j) >>> complex(0+0.0j) 0j Both, the constructor and the docstring, are not so clean. What to say about the __repr__ ? Are not a and b supposed to be floats? (elements of R) >>> 0 0 >>> 0.0 0.0 >>> 0j 0j >>> 1.0 + 2.0j (1+2j) >>> 1. 1.0 >>> 1 1 >>> (1 + 2.0j).real 1.0 >>> type((1 + 2.0j).real) <class 'float'> jmf -- https://mail.python.org/mailman/listinfo/python-list
