Parity blocks can not be higher than data blocks, so `STANDARD` storage class parity can not be higher than N/2. (N being total number of drives)

The default value for the `STANDARD` storage class depends on the number of volumes in the erasure set:

| Erasure Set Size | Default Parity (EC:N) |
|------------------|-----------------------|
| 5 or fewer       |                 EC:2  |
| 6-7              |                 EC:3  |

	if animal.Name != "amazing horse" {
		t.Errorf("Update a filed with a default value should occur. But got %v\n", animal.Name)
	}

	// When changing a field with a default value with blank value
	animal.Name = ""
	DB.Save(&animal)
	DB.First(&animal, animal.Counter)
	if animal.Name != "" {
		t.Errorf("Update a filed to blank with a default value should occur. But got %v\n", animal.Name)
	}

```

/// tip

The second argument to <a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> is the default value to return.

If not provided, it's `None` by default, here we provide `"World"` as the default value to use.

Then you could call that Python program:
