## 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

        dst[dstIndex] = (byte) val;
        dstIndex++;
        dst[dstIndex] = (byte) (val >>= 8);
        dst[++dstIndex] = (byte) (val >>= 8);
        dst[++dstIndex] = (byte) (val >> 8);
    }

    /**
     * Reads a 16-bit integer value from a byte array in little-endian format
     * @param src the source byte array
     * @param srcIndex the starting index in the source array
     * @return the 16-bit integer value
     */

        int result = smbRandomAccessFile.read();
        assertEquals(42, result);
        assertEquals(1, smbRandomAccessFile.getFilePointer());
    }

    @Test
    void testReadEOF() throws SmbException {
        // Mock the read operation to return EOF
        doAnswer(new Answer<Void>() {
            @Override

		Method: Deflate,
		Mode:   0755 | fs.ModeDevice | fs.ModeCharDevice,
	},
}

func TestWriter(t *testing.T) {
	largeData := make([]byte, 1<<17)
	if _, err := rand.Read(largeData); err != nil {
		t.Fatal("rand.Read failed:", err)
	}
	writeTests[1].Data = largeData
	defer func() {
		writeTests[1].Data = nil
	}()

	// write a zip file
	buf := new(bytes.Buffer)
	w := NewWriter(buf)

     */
    int read(byte[] b) throws SmbException;

    /**
     * Read into buffer from current position
     *
     * @param b
     *            buffer
     * @param off
     *            offset into buffer

 *  **Beta WebSockets support.**. The `okhttp-ws` subproject offers a new
    websockets client. Please try it out! When it's ready we intend to include
    it with the core OkHttp library.

 *  **Okio updated to 1.3.0.**
