Question
class Student: def init(self,name,id): self.name=name self.id=id print(self.id)std=Student("Simon",1)std.id=2print(std.id)
Solution
The code you provided is written in Python and it defines a class named Student with a constructor method (__init__). This method is used to initialize new instances of the class.
Here's a step-by-step explanation of what the code does:
-
The
Studentclass is defined with two attributes:nameandid. -
The
__init__method is a special method in Python classes, it is the constructor method. When a new instance of the class is created, this method is immediately executed with the given arguments. -
In the
__init__method,self.name=nameandself.id=idset the attributes of the class instance to the provided arguments. -
print(self.id)will print theidof the student when a new instance is created. -
std=Student("Simon",1)creates a new instance of theStudentclass with the name "Simon" and id 1. This will also print "1" because of theprint(self.id)line in the__init__method. -
std.id=2changes theidof thestdinstance to 2. -
print(std.id)prints the currentidof thestdinstance, which is now 2.
