Cannot call keyword in robotframework that created from import module

Question

I'm new to robotframework and python. Recently I'd try to create custom keyword in python file and then import it by robotframework. It can import normally but I can't call method in python file as a keyword. Here is my example

from robot.api import logger    
from robot.utils.asserts import fail    
from robot.utils import get_link_path    
from robot.libraries.BuiltIn import BuiltIn    
from robot.api.deco import keyword

class MyCustomClass():

    ROBOT_LIBRARY_VERSION = 1.0
    
    def __init__(self):
        pass

    def justprint(self):
        print('HelloWorld')

I try to call justprint as a keyword but can't.Here is the path in robotframework to call this .py file (../Web/02_RobotScriptExtract/Custom_Selenium_Keywords.py) It doesn't turn red, and I call it as library.

I assume that it is because of library which I imported, any ideas?

dear friend.. dont post the code as image. please copy paste. — Subbu VidyaSekar, Sep 03 '20 at 05:05
I've update how I import the lib, and the way I call the keyword is I actually type the justprint in robotfile and then press ctrl+space but nothing is display — NoobMaster69, Sep 03 '20 at 07:27

You are trying to import the library as a Robotframework library, hence the proper way to do it in a test case file will be: (Note that the class have to be in the PYTHONPATH)

*** Settings ***
Library  MyCustomClass

*** Test Cases ***
Test case name
    justprint

If you just want to add a python file and use the functions from this file as keywords, then do:

*** Settings ***
Library  path_to_file/MyCustomPythonFile

*** Test Cases ***
Test case name
    justprint

In this case, your MyCustomPythonFile file will only contain the function. There is no need to have a class:

def justprint(self):
        print('HelloWorld')

Please note that the fact that you do Ctrl + Space and there is no autocompletion doesn't mean that the keyword is not imported. It could be a misconfiguration with your IDE. Instead, run the test case to verify.
