## Omgevingsvariabelen uitlezen in Python

Je kunt omgevingsvariabelen **buiten** Python aanmaken, in de terminal (of met een andere methode) en ze vervolgens **in Python uitlezen**.

Je kunt bijvoorbeeld een bestand `main.py` hebben met:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")

        map.put("boost1", 0);
        map.put("boost2", 0);
        assertTrue(0.0f == docBoostMatcher.getValue(map));

        map.put("boost1", 1);
        map.put("boost2", 0);
        assertTrue(10.0f == docBoostMatcher.getValue(map));

        map.put("boost1", 1);
        map.put("boost2", 2);
        assertTrue(12.0f == docBoostMatcher.getValue(map));
    }

        requestBody.put("name", "test_webconfig");
        requestBody.put("urls", "http://www.example.com");
        requestBody.put("user_agent", "Mozilla/5.0");
        requestBody.put("num_of_thread", 5);
        requestBody.put("interval_time", 1000);
        requestBody.put("boost", 100.0);
        requestBody.put("available", true);
        requestBody.put("sort_order", 1);

        final Map<String, String> valueMap = new LinkedHashMap<>();
        valueMap.put("action", Action.ACCESS.name());
        valueMap.put("user", user.map(FessUserBean::getUserId).orElse("-"));
        valueMap.put("path", path);
        valueMap.put("execute", execute);
        log(valueMap);
    }

    public void permissionChanged(final OptionalThing<FessUserBean> user) {

        map.put(ConfigName.CONFIG, configConfigMap);
        map.put(ConfigName.CLIENT, clientConfigMap);

        doc.put(KEY_PROPERTY, keyProp);

        doc.put("boost", id);
        doc.put("role", "Rguest");
        requestBody.put("doc", doc);
        return requestBody;
    }

    @Override
    protected Map<String, Object> createSearchBody(final int size) {

        requestBody.put("name", NAME_PREFIX + "WebConfig");
        requestBody.put("urls", urls);
        requestBody.put("included_urls", includedUrls);

        virtualHostList.add("site1");
        dataMap.put("virtual_host", virtualHostList);
