Python 将字典分配给属性

Question

i have a class a kind like this:

class equipment():
     def __init__(self, l, d):
          self.length = {"desc": "Length of equipment", "val":l, "unit":"ft"}
          self.diameter = {"desc": "Diameter of equipment", "val":d, "unit":"inch"}

so im needing a constructor for the properties something line

class fisicalProp():
   def __init_(self, d, v, u)
       self.something = {"desc": "Diameter of equipment", "val":d, "unit":"inch"}

then i only call

class equipment():
         def __init__(self, l, d):
              self.length = fisicalPropertie("Length of equipment",l, "ft"}
              self.diameter = fisicalPropertie("Diameter of equipment", d, "inch"}

can you help me to improve my code like that?

Answer 1

Why do you complicate this action? If you use this class for several instances, you don't need to create dict here. Therefore, if are not going to use inheritance, don't need to use () with class definition

class equipment:
    def __init__(self, length, len_units, diameter, dia_units):
        self.length = (length, len_units)
        self.diameter = (diameter, dia_units)

eq = equipment(1, "ft", 2, "inch")
print(eq.length, eq.diameter)
