## 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

			b = append(b, 0)[:len(b)]
		}
		n, err := r.Read(b[len(b):cap(b)])
		b = b[:len(b)+n]
		if err != nil {
			if errors.Is(err, io.EOF) {
				if want >= 0 && read+int64(n) != want {
					return nil, io.ErrUnexpectedEOF
				}
				err = nil
			}
			return b, err
		}
		read += int64(n)
		if want >= 0 && read == want {
			// No need to read more...
			return b, nil
		}
	}
}
