+# Dict
+
+You can declare a *CLI parameter* to be a standard Python `dict`:
+
+{* docs_src/parameter_types/dict/tutorial001_an.py hl[5] *}
+
+Check it:
+
+<div class="termy">
+
+```console
+// Run your program
+$ python main.py --user-info '{"name": "Camila", "age": 15, "height": 1.7, "female": true}'
+
+Name: Camila
+User attributes: ['age', 'female', 'height', 'name']
+
+```
+
+</div>
+
+This can be particularly useful when you want to include JSON input:
+
+```python
+import json
+
+data = json.loads(user_input)
+```
