Parameters:
dotenv_path: Absolute or relative path to .env file.
stream: Text stream (such as `io.StringIO`) with .env content, used if
`dotenv_path` is `None`.
verbose: Whether to output a warning the .env file is missing.
override: Whether to override the system environment variables with the variables
from the `.env` file.
encoding: Encoding to be used to read the file.
Returns:
Bool: True if at least one environment variable is set else False
If both `dotenv_path` and `stream` are `None`, `find_dotenv()` is used to find the
.env file.

Parse a .env file and return its content as a dict.
The returned dict will have `None` values for keys without values in the .env file.
For example, `foo=bar` results in `{"foo": "bar"}` whereas `foo` alone results in
`{"foo": None}`
Parameters:
dotenv_path: Absolute or relative path to the .env file.
stream: `StringIO` object with .env content, used if `dotenv_path` is `None`.
verbose: Whether to output a warning if the .env file is missing.
encoding: Encoding to be used to read the file.
If both `dotenv_path` and `stream` are `None`, `find_dotenv()` is used to find the
.env file.
