create a file outside the directory in python

I want to create a file outside the current working directory in python. Here's my directory structure.

|--myproject
|   |-- gui
|   |   |-- modules
|   |   |   |-- energy
|   |   |   |   |-- configuration
|   |   |   |   |   |-- working_file.py
|   |-- service
|   |   |-- constants
|   |   |   |-- global_variables.json    

I'm current working in /myproject/gui/energy/configuration/working_file.py and I want to create a file under /myproject/service/constants named global_variables.json

I tried

with open("../../../../../service/constants/global_variables.json", 'w') as file_handler:
        content = json.load(file_handler)
