My understanding of the @property decorator is that it is only for
defining read-only properties. In other wordss it expects you to use it
t = Tutto()
myvar = t.readsets
notice no parens and no parameters.
If you want to read the data from a file I'd suggest making the file
part of the constructor and then use readsets as shown above:
def __init__(self, filename):
self.filename = filename
self._readsets = parse_tutto_readset_file(self.nome)
p = Tutto("/home/mauro/Desktop/readset.csv")
var = p.readsets
I'd also question why you seem to have a function that has the class
name in its name? Should that function not be a method of the class?
Or is it part of some third party library perhaps?
