Question
What will be the output of below Python code?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 1
The output of the Python code will be:
1 2
Here's the step by step explanation:
-
A class named
Studentis defined with an__init__method. The__init__method is a special method in Python classes which is automatically called when an object of the class is created. It is used to initialize the attributes of the class. -
The
__init__method takes three parameters:self,name, andid.selfis a reference to the current instance of the class and is used to access variables and methods associated with the class.nameandidare the parameters passed when creating an instance of the class. -
Inside the
__init__method,self.nameandself.idare set to the values ofnameandidpassed as parameters. Then,self.idis printed. -
An instance of the
Studentclass is created with the name "Simon" and id 1. This will print the id, which is 1. -
The id of the
stdinstance is then changed to 2. -
Finally, the id of the
stdinstance is printed, which is now 2.
Solution 2
The output of the Python code will be:
1 2
Here's the step-by-step explanation:
-
The class
Studentis defined with an__init__method. This method is a special method in Python classes which is automatically called when an object of the class is created. It is used to initialize the attributes of the class. -
In the
__init__method,self.nameandself.idare defined.selfrefers to the instance of the class.self.nameandself.idare instance variables. Their values are set to the arguments passed during the creation of the object. -
When the object
stdis created with the arguments "Simon" and 1, the__init__method is called. Theself.idis set to 1 and then printed. So, 1 is the first output. -
Then,
std.idis set to 2. This changes theidof thestdobject from 1 to 2. -
Finally,
std.idis printed, which is now 2. So, 2 is the second output.
Solution 3
The output of the Python code will be as follows:
1 2
Here's the step-by-step explanation:
-
A class named
Studentis defined with an__init__method. The__init__method is a special method in Python classes which is automatically called when an object of the class is created. It is used to initialize the attributes of the class. -
The
__init__method takes three parameters:self,name, andid.selfis a reference to the current instance of the class and is used to access variables and methods associated with that instance.nameandidare the parameters that will be passed when creating objects of the class. -
Inside the
__init__method, two instance variablesself.nameandself.idare initialized with the values ofnameandidrespectively. Then,self.idis printed. -
An object of the
Studentclass is created with the name "Simon" and id 1. This will print the id, which is 1. -
The id of the
stdobject is then changed to 2. -
Finally, the id of the
stdobject is printed, which is now 2.

The output of the Python code will be:
1 2
Here's the step by step explanation:
-
A class named
Studentis defined with an__init__method. This method is a special method in Python classes which is automatically called when an object of the class is created. It is used to initialize the attributes of the class. -
The
__init__method takes three parameters:self,name, andid.selfis a reference to the current instance of the class and is used to access variables and methods associated with that instance.nameandidare the parameters that will be passed when creating objects of the class. -
Inside the
__init__method,self.nameandself.idare set to the values ofnameandidpassed as parameters. Then,self.idis printed. -
An object of the
Studentclass is created with the name "Simon" and id 1. This will print1because theprint(self.id)statement in the__init__method is executed. -
The id of the
stdobject is then changed to2using the statementstd.id=2. -
Finally,
std.idis printed, which will output2.

An object of the class
Studentis created with the name "Simon" and id 1. This will print1because of the print statement in the__init__method. -
The id of the
stdobject is then changed to2. -
Finally,
std.idis printed, which will output2.
