## Read env vars in Python { #read-env-vars-in-python }

You could also create environment variables **outside** of Python, in the terminal (or with any other method), and then **read them in Python**.

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")
```

    }
  }

  /** Helper method that asserts the arithmetic mean of x and y is equal to the expectedMean. */
  private static void assertMean(long expectedMean, long x, long y) {
    assertEquals(
        "The expectedMean should be the same as computeMeanSafely",
        expectedMean,
        computeMeanSafely(x, y));
    assertMean(x, y);
  }

#### Running doctest for testable docstring

There are two ways to test the code in the docstring locally:

1.  If you are only changing the docstring of a class/function/method, then you
    can test it by passing that file's path to
    [tf_doctest.py](https://www.tensorflow.org/code/tensorflow/tools/docs/tf_doctest.py).
    For example:

    ```bash

        try {
            indexUpdateCallback.isUrlCrawlable(paramMap, null);
            fail("Expected NullPointerException for null URL");
        } catch (NullPointerException e) {
            // Expected behavior - the method doesn't handle null URLs
        }
    }

    public void test_isUrlCrawlable_nullUrlWithoutPattern() {
        DataStoreParams paramMap = new DataStoreParams();

        }
        return redirect(getClass()); // no-op
    }

    /**
     * Creates a CURL request from the provided header string.
     *
     * @param header the header string containing HTTP method and path
     * @return CURL request object or null if header is invalid
     */
    private CurlRequest getCurlRequest(final String header) {
        if (StringUtil.isBlank(header)) {
            return null;
