Python is a high-level programming language, which is increasingly in demand in industries such as data science, machine learning, and web development. One of the reasons why Python is being preferred over other languages is due to its dynamic nature. This article focuses on one such feature of Python, namely dynamically adding the @property decorator to a class attribute.

Dynamic Python

Python is an interpreted language, which means that the code is executed at runtime. It allows us to change the program behavior based on input or any other data that gets handled by the program. Dynamic Python is all about allowing us to write code that changes itself according to changing conditions during its execution.

The @property Decorator

@property is a built-in decorator in Python, and it is used to define a method as a read-only attribute of an object. Usually, class attributes can be accessed using the dot (.) notation. However, if we want to compute the attribute value, rather than storing it, we can use the @property decorator.

Example: Using @property Decorator

Let’s take an example where we have a class Employee, and we want to calculate the salary of the employee based on hours worked and hourly wage. Here is how we can use the @property decorator to dynamically compute the salary:“`pythonclass Employee: def __init__(self, name, hours_worked, hourly_wage): = name self.hours_worked = hours_worked self.hourly_wage = hourly_wage @property def salary(self): return self.hours_worked * self.hourly_wage“`When we access the salary attribute of an Employee object, it will compute the salary dynamically based on the hours worked and hourly wage.

Dynamically Adding @property

In some cases, we may not know in advance if a property needs to be computed dynamically. However, we may decide to add the @property decorator to a class attribute at runtime. Python allows us to do that using the built-in setattr() function.

Example: Dynamically Adding @property Decorator

Let’s take the same Employee class example and see how we can add the @property decorator dynamically to the salary attribute:“`pythonclass Employee: def __init__(self, name, hours_worked, hourly_wage): = name self.hours_worked = hours_worked self.hourly_wage = hourly_wagee = Employee(John, 8, 10)setattr(Employee, ‘salary’, property(lambda self: self.hours_worked * self.hourly_wage))print(e.salary) # output: 80“`We create an instance of the Employee class and then use the setattr() function to set the ‘salary’ attribute as a property. We pass a lambda function to the property(), which calculates the salary based on hours worked and hourly wage.


When it comes to dynamically adding @property on the fly, Python is a clear winner. Although other languages such as Java and C++ provide ways to add dynamic properties to objects, Python’s dynamic nature makes it easy and intuitive.

Language Dynamically Add @property
Python Yes
Java Yes (using reflection)
C++ Yes (using macros)


Python’s dynamic nature provides a lot of flexibility to developers, and adding the @property decorator on the fly is just one such example. Although this feature may not be used frequently, it shows the power of Python’s dynamic capabilities. In the end, it all comes down to personal preference and project requirements. However, if you want to write code that adapts to changing conditions at runtime, Python is the language to go for.

People also ask about Dynamic Python: Adding @Property On The Fly

  1. What is dynamic Python?
  2. Dynamic Python is a programming language that allows for rapid development and testing of code. It is known for its ability to dynamically change the type of variables and objects during runtime.

  3. What is the use of @property in Python?
  4. The @property decorator in Python is used to convert a method into a read-only property. It allows you to access attributes like a normal variable, but with the added benefit of being able to perform additional actions such as input validation or data manipulation.

  5. What does it mean to add @property on the fly?
  6. Adding @property on the fly means that you can dynamically create and add properties to a class during runtime. This can be useful if you need to add functionality to an already existing class without having to modify its source code.

  7. How do you add @property on the fly in Python?
  8. To add @property on the fly in Python, you can use the built-in type() function to dynamically create a new class with the desired properties. You can then instantiate this class and access the new properties as if they were defined in the original class.
