To get the value of an attribute I need to call method.attribute.attribute instead of method.attribute, why is this? Calling method.attribute results in a memory address. How should/can I change my code to make method.attribute work?
Most issues regarding this center around calling print(f) instead of print(f())
class MyList:
"""stores a list and does other stuff eventualy"""
this_list = []
def __init__(self, *args):
for arg in args:
self.this_list.append(arg)
def print_list(self):
"""prints the atribute:"description" from the stored objects in the list"""
for x in range(len(self.this_list)):
print(MyClassObj(self.this_list[x]).description, sep="\n")
This is the code that is supposed to print the value of the attribute description
class MyClassObj:
"""test object to be stores in the "MyList" object."""
def __init__(self, description):
self.description = description
This is the object that contains the attribute I want to get.
class CallList:
"""creates the objects, lists and calls the print method"""
@staticmethod
def main():
test1, test2 = MyClassObj("Test1"), MyClassObj("Test2")
list1 = MyList(test1, test2)
list1.print_list()
Main() is called outside the above classes.
The output I get is
<__main__.MyClassObj object at 0x007908F0>
<__main__.MyClassObj object at 0x00790910>
Process finished with exit code 0
If i change line:
print(MyClassObj(self.this_list[x]).description.description, sep="\n")
I get the expected result:
Test1
Test2
Process finished with exit code 0
So the question is why and how should I alter my code?
in print_list self.this_list[x] is already a MyClassObj so MyClassObj(self.this_list[x]) creates a new MyClassObj having a MyClassObj as its description.
Because there is no way defined to convert a MyClassObj to a string for print Python uses a default conversion showing the memory address.
