## 在 Python 中读取环境变量

你也可以在 Python **之外**的终端中创建环境变量（或使用任何其他方法），然后在 Python 中**读取**它们。

例如，你可以创建一个名为 `main.py` 的文件，其中包含以下内容：

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip

第二个参数是 <a href="https://docs.python.org/zh-cn/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> 的默认返回值。

	Signature [4]byte
	Type      VersionType
	Flags     xlFlags
	EcN, EcM  uint8 // Note that these will be 0/0 for non-v2 objects and older xl.meta
}

func (x xlMetaV2VersionHeader) String() string {
	return fmt.Sprintf("Type: %s, VersionID: %s, Signature: %s, ModTime: %s, Flags: %s, N: %d, M: %d",
		x.Type.String(),
		hex.EncodeToString(x.VersionID[:]),
		hex.EncodeToString(x.Signature[:]),
		time.Unix(0, x.ModTime),

		if deploymentID != formats[i].ID {
			return nil, fmt.Errorf("all pools must have same deployment ID - expected %s, got %s for pool(%s)", deploymentID, formats[i].ID, humanize.Ordinal(i+1))
		}

		bootstrapTrace(fmt.Sprintf("newErasureSets: initializing %s pool", humanize.Ordinal(i+1)), func() {
			z.serverPools[i], err = newErasureSets(ctx, ep, storageDisks[i], formats[i], commonParityDrives, i)
		})
		if err != nil {
			return nil, err

```

そして呼び出すと:

```Python
user_dict = user_in.dict()
```

これで変数`user_dict`のデータを持つ`dict`ができました。（これはPydanticモデルのオブジェクトの代わりに`dict`です）。

そして呼び出すと:

```Python
print(user_dict)
```

以下のようなPythonの`dict`を得ることができます:

```Python
{
    'username': 'john',
    'password': 'secret',
    'email': '******@****.***',
    'full_name': None,
}
```

		{"192.168.1.210:9000", Endpoint{}, -1, fmt.Errorf("invalid URL endpoint format: missing scheme http or https")},
	}

	for i, test := range testCases {
		t.Run(fmt.Sprint("case-", i), func(t *testing.T) {
			endpoint, err := NewEndpoint(test.arg)
			if err == nil {
				err = endpoint.UpdateIsLocal()
			}

			switch {
			case test.expectedErr == nil:
				if err != nil {

				},
				{
					PartNumber: 2,
					Algorithm:  HighwayHash256S,
					Hash:       nil,
				},
			},
		},
	}
	for _, size := range []int{1, 10, 1000, 100_000} {
		b.Run(fmt.Sprint(size, "-versions"), func(b *testing.B) {
			var xl xlMetaV2
			ids := make([]string, size)
			for i := range size {
				fi.VersionID = mustGetUUID()
				fi.DataDir = mustGetUUID()
				ids[i] = fi.VersionID

## 在 Python 中讀取環境變數

你也可以在 Python **之外**的終端機中建立環境變數（或使用其他方法），然後在 Python 中**讀取**它們。

例如，你可以建立一個名為 `main.py` 的檔案，其中包含以下內容：

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip

第二個參數是 <a href="https://docs.python.org/zh-tw/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> 的預設回傳值。

Here are the affected tests:
EOF
    while read dep; do
      echo "For dependency $dep:"
      # For every missing dependency, find the tests which directly depend on
      # it, and print that list for debugging. Not really clear if this is
      # helpful since the only examples I've seen are enormous.
      bazel cquery "rdeps(kind(py_test, $(cat $BATS_TEST_TMPDIR/deps)), $dep, 1)"

		return fmt.Errorf("unable to list IAM data: %w", err)
	}
	if took := time.Since(listStartTime); took > maxIAMLoadOpTime {
		var s strings.Builder
		for k, v := range listedConfigItems {
			s.WriteString(fmt.Sprintf("    %s: %d items\n", k, len(v)))
		}
		logger.Info("listAllIAMConfigItems took %.2fs with contents:\n%s", took.Seconds(), s.String())
	}

	// Loads things in the same order as `LoadIAMCache()`
