You can compare it with the *enumeration member* in your created enum `ModelName`:

{* ../../docs_src/path_params/tutorial005_py39.py hl[17] *}

#### Get the *enumeration value* { #get-the-enumeration-value }

You can get the actual value (a `str` in this case) using `model_name.value`, or in general, `your_enum_member.value`:
