+
+### python requirements
+
+Install [python-dotenv](https://pypi.org/project/python-dotenv/)
+

+
+
+### Reading `.env`
+
+```python
+# read env vars
+# S/O https://stackoverflow.com/a/61029741
+load_dotenv()
+token = os.getenv('token')
+gist_id = os.getenv('gist_id')
+filename = os.getenv('filename')
+```
+
+
+### write current machine ip address to gist file
+
+```python
+# fetch external ip address
+# S/O https://stackoverflow.com/a/36205547
+ip_addr = requests.get('https://api.ipify.org').content.decode('utf8')
+
+# request gist changes
+# S/O https://stackoverflow.com/a/65761251
+headers = {'Authorization': f'token {token}'}
+request_url = f'https://api.github.com/gists/{gist_id}'
+request_data = json.dumps({'files':{filename:{"content":ip_addr}}})
+
+r = requests.patch(
+    url=request_url,
+    data=request_data,
+    headers=headers)
+```

+request_url = f'https://api.github.com/gists/{gist_id}'
+request_data = json.dumps({'files':{filename:{"content":ip_addr}}})
+r = requests.get(
+    url=request_url,
+    data=request_data,
+    headers=headers)
+gist_content = r.json()['files'][filename.strip()]['content']
