## 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

        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
