    }

i want to extract the **definition** part only .see below

                                

    "definitions": [
                                        "make it easier or possible for (someone) to do something by offering them one's services or resources"
                                    ],

 you can see there is a definition part in the output . how to do this in python .there are so many definition available i just want the first one
