For example you could have a file `main.py` with:

```Python hl_lines="3"
import os

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

!!! 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.

val platform = System.getProperty("okhttp.platform", "jdk9")
val testJavaVersion = System.getProperty("test.java.version", "21").toInt()

tasks.withType<Test> {
  useJUnitPlatform()
  onlyIf("By default not in CI") {
    System.getenv("CI") == null
      || (project.hasProperty("containerTests") && project.property("containerTests").toString().toBoolean())
  }

  jvmArgs(
    "-Dokhttp.platform=$platform",
  )

  if (platform == "loom") {

例如，您可以有一个名为 `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
    <a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> 的第二个参数是要返回的默认值。

    如果没有提供默认值，默认为 `None`，此处我们提供了 `"World"` 作为要使用的默认值。

然后，您可以调用该 Python 程序：
