Question
Consider the following Python code snippet: class
Employee:   def __init__(self, name, age):     self.name = name     self.age = age   def display(self):     print(f"Name: {self.name}, Age: {self.age}") e1 = Employee("John", 30) e1.salary = 50000 e1.display() print(e1.salary) What will happen when the above code is executed?Solution
The code demonstrates Python's ability to dynamically add attributes to an instance of a class. 1. Instance Attributes: While name and age are initialized in the __init__ method, the salary attribute is added dynamically to the e1 instance after the object is created. Python allows this flexibility without any compile-time errors. 2. Output Explanation: When e1.display() is called, the display method prints name and age. Then, e1.salary is accessed and printed directly. 3. Execution Result: The code will output: Name: John, Age: 30  50000  This behavior demonstrates Python's dynamic nature and object-oriented principles. Why Other Options Are Incorrect: • A) It will print the name, age, and salary of the employee: The display method does not include salary, so salary is not printed there. • B) It will raise an AttributeError when accessing e1.salary: Python allows adding attributes dynamically; no error occurs. • D) It will execute but not print the salary attribute: e1.salary is explicitly printed in the last line. • E) It will fail to execute due to missing method to initialize salary: There is no requirement for salary to be initialized in the __init__ method.
