How to Write Class in Ubuntu Python

Python supports object-oriented programming, which makes python powerful. Creating class in Ubuntu python explained. You can use it in different ways by assigning it to an object. Doing all these are explained in the below steps.

Here is a logic you can create a script with Class and Objects

Writing Class in Python in 3 Steps

  1. Python code
  2. Write the code in script
  3. Execute script

Writing Class in Python

Below sample code my give indentation errors. However, I have corrected the code in the actual script.

class Employee:
"""Base class"""
empCount = 0

def __init__(self, name, salary): = name
self.salary = salary
Employee.empCount += 1

# can also be written as Employee.empCount = Employee.empCount + 1
def displayEmployee(self): # function is defined here
print "Name : ",, ", Salary: ", self.salary

# "emp1 is the first object of Employee class"
emp1 = Employee("Akhil", 2000)

# "emp2 is the second object of Employee class"
emp2 = Employee("Suresh", 5000)
print ("Total Employee %d" % Employee.empCount)

Python Script

You need to use vim command to create a script in Ubuntu.  You can do any Linux operating system for practice.

$ vim

Python Class and Object in a Script


In python,' init' is a mandatory method with 'self' you need to give. The arguments 'name' and 'salary' are optional to you. Here I used two objects of Employee - emp1 and emp2. The Employee is the base class.

These objects used the "displayEmployee" method. According to the print definition, you got the below output details.

The last print has two characters. One is %d and %. The %d, pads a blank. If you want more, you can write %2d, %3d, and so on.

Executing script

From Python Console, get the .py module using the "import" command. It runs as and when the import completes.

  • The command to import is - >>> import
  • When I imported, it displayed the messages as expected.
