Python Coding challenge - Day 1237| What is the output of the following Python Code?

 

Code Explanation:

🔹 1. Importing dataclass

from dataclasses import dataclass

✅ Explanation

dataclass is a decorator from Python's built-in dataclasses module.

It automatically generates useful methods like:

__init__()

__repr__()

__eq__()

When order=True is used, it also generates comparison methods:

__lt__() (<)

__le__() (<=)

__gt__() (>)

__ge__() (>=)

Current Memory

dataclass Imported

🔹 2. Applying the Decorator

@dataclass(order=True)

✅ Explanation

@dataclass converts the class into a data class.

order=True tells Python to automatically create comparison methods.

Internally, Python creates methods similar to:

__lt__()

__le__()

__gt__()

__ge__()

Visual Representation

Student Class

↓

@dataclass(order=True)

↓

Auto Generates

✔ __init__()

✔ __repr__()

✔ __eq__()

✔ __lt__()

✔ __gt__()

🔹 3. Creating the Class

class Student:

✅ Explanation

A class named Student is created.

Current Memory

Class

Student

🔹 4. Declaring the Data Field

marks: int

✅ Explanation

The class has one attribute:

marks

Its expected type is int.

Current Memory

Student

↓

marks

🔹 5. Creating the First Object

Student(80)

✅ Explanation

Python automatically calls the generated constructor.

Internally

Student.__init__(80)

Current Memory

Student 1

+-----------+

| marks=80  |

+-----------+

🔹 6. Creating the Second Object

Student(90)

✅ Explanation

Python creates another object.

Current Memory

Student 2

+-----------+

| marks=90  |

+-----------+

🔹 7. Comparing the Objects

Student(80) < Student(90)

✅ Explanation

Since order=True is used, Python automatically calls the generated __lt__() method.

Internally

Student(80).__lt__(Student(90))

Python compares

80 < 90

Result

True

Visual Representation

Student(80)

marks = 80

        <

Student(90)

marks = 90

↓

80 < 90

↓

True

🔹 8. Printing the Result

print(Student(80) < Student(90))

✅ Explanation

Python prints the comparison result.

Output

True

🎯 Final Output

True
