Question
class Student: def init(self,name,id): self.name = name self.id = id print(self.id, end=" ")std1=Student("Mark",1)std2=Student("May",2)std2.id=2print(std2.id, end=" ")
Solution
The code you provided is written in Python. It defines a class named Student with a constructor that takes two parameters: name and id. The constructor sets these parameters to instance variables and then prints the id.
Then, it creates two instances of the Student class: std1 with name "Mark" and id 1, and std2 with name "May" and id 2. After that, it sets the id of std2 to 2 again (which is redundant because it was already 2), and then prints the id of std2.
Here is a step-by-step explanation:
-
class Student:This line defines a new class namedStudent. -
def __init__(self,name,id):This line defines the constructor of theStudentclass. The constructor is a special method that is called when an instance of the class is created. It takes three parameters:self,name, andid.selfis a reference to the instance of the class, andnameandidare the values that will be used to initialize the instance. -
self.name = nameandself.id = idThese lines set thenameandidof the instance to the values passed to the constructor. -
print(self.id, end=" ")This line prints theidof the instance, followed by a space instead of a newline (because ofend=" "). -
std1=Student("Mark",1)This line creates a new instance of theStudentclass with name "Mark" and id 1, and assigns it to the variablestd1. -
std2=Student("May",2)This line creates a new instance of theStudentclass with name "May" and id 2, and assigns it to the variablestd2. -
std2.id=2This line sets theidofstd2to 2. This is redundant because theidwas already 2. -
print(std2.id, end=" ")This line prints theidofstd2, followed by a space instead of a newline.
The output of this code will be: 1 2 2
