I am importing a python libraries and wanted to create two objects with different arguments and call method defined in the class.

demo.py

class Sample:

    def __init__(self,path,device):
            self.device=device
            self.path = path
            print(self.device)
            print(self.path)

    def getting_path(self):
            print(self.path)
            print(self.device)
            return self.path

demo.robot
===============
*** Settings ***
*** Variables ***
${path}    c:
${device}    samsung
${path1}    D:
${device1}    samsung11

Test_python_class
     Import Library      demo.Sample    ${path1}    ${device1}    
     ${result} =     demo.sample.getting_path
     log     ${result}
     Import Library      demo.Sample    ${path}    ${device}
     ${result1} =     demo.sample.getting_path
     log     ${result1}

It is not creating second object. ${result} and {result1} printing the same value.

I can achieve this by using below syntax using WITH name with two value. and calling like below using WITH NAME

Import Library      demo.Sample    ${path1}    ${device1}    With Name     c1
     ${result} =     c1.getting_path
     log     ${result}
     Import Library      demo.Sample    ${path}    ${device}   With Name     c2
     ${result1} =     c2.getting_path
     log     ${result1}

But this solution is not optimal. If I need to create 10 objects with different value , I need to use 10 import statements here.

Appreciate if anybody can provide any inputs on optimum solution, where I can define this steps as robot function/keyword which will take these arguments for constructor and return me the object handle so that we can call class method using different object.

Robot framework isn't really designed to create objects this way. When you use the import library keyword (or the Library setting), robot expects a keyword library, not a standard python module.

Instead, I recommend creating a proper keyword library which has a keyword for creating your objects.

For example, start with a SampleLibrary.py file that looks like this:

# SampleLibrary.py
from demo import Sample

class SampleLibrary:
    def get_sample(self, path, device):
        return Sample(path, device)

Then, in your test you would do something like this:

*** Settings ***
Library  SampleLibrary

*** Test Cases ***
Example
    ${sample1}=  get sample  ${path}   ${device}
    Call method  ${sample1}  getting_path

    ${sample2}=  get sample  ${path1}  ${device1}
    Call method  ${sample2}  getting_path
