I have a class that reads an XML file and with the file information fills the class attributes. All the data consistency checks I do within the "setters" of the attributes (the class can be used without the input file, directly by another code and so I don’t need to repeat the checks on other parts of the code).
For example, I have Setter:
@fluid_list.setter
def fluid_list(self, fluid_list: []):
for i in fluid_list:
self.__fluid_list.append(fluid_list[i].upper())
assert (len(fluid_list) == len(set(fluid_list)))
assert (len(np.setdiff1d(fluid_list,["OIL", "WATER", "GAS"])) == 0)
And I have the method
def read_file(self):
try:
# parse an xml file by name
mydoc = minidom.parse(self.__input_file_name)
# reads function elements to get all function names (FunctionList)
list_elem = mydoc.getElementsByTagName('fluid')
fluid_l = []
for elem in list_elem:
fluid_l.append(elem.firstChild.data)
self.fluid_list(fluid_l)
print(self.__fluid_list)
except Exception as e:
logger.catch_error(e)
While running I get the following error message:
File "...prj\InputData.py", line 158, in read_file self.fluid_list(fluid_l)
TypeError: 'list' object is not callable
Is there any way to call Setter within the class, or need to include consistency checking in the method that reads the input file?
self.fluid_list(fluid_l), that should beself.fluid_list = fluid_lif the intention is to call the Setter of your property.– Woss
And make the parameter
fluid_list: []seems to make no sense. In this case the[]will be a type note and it would not make much sense to be[]. If the idea was to set a default value, it should befluid_list = [], but you still need to be very careful with When a default argument is evaluated in Python– Woss
Yes, that’s the intention and it worked perfectly. My first implementation was this way, but there must have been something wrong elsewhere in the code because it hadn’t worked... Thank you very much!
