Access IATE API programmatically using PYTHON

The IATE terminology database is accessible for search and research purposes on the address https://iate.europa.eu and can be accesses programatically using the API. A description of their endpoints and procedures is available at https://iate.europa.eu/developers
Here is a Python script to use this database from the command line or even as a program line in Goldendict (always use latest RC version, not the stable 1.0.1 version).
This line is for using the Programs function in Goldendict as HTML type:
python IATEPOST.py de ro %GDWORD%
or try
cmd.exe /c chcp 65001 > nul & python IATEPOST.py de ro %GDWORD%
if you encounter unicode problems,
where "de" and "ro" are the language codes for the source and the target language.

#!/usr/bin/env python3
#PYTHONIOENCODING='utf-8'
#PYTHONLEGACYWINDOWSSTDIO='utf-8'
# -*- coding: utf-8 -*-
import json
import requests
import sys

"""
To use, just run the Python script:
python IATEPOST.py de ro %GDWORD%
where "de" and "ro" are the language codes for the source and the target language.
