Python-dotenv reads key-value pairs from a `.env` file and can set them as environment
variables. It helps in the development of applications following the
[12-factor](http://12factor.net/) principles.

## Getting Started
```shell
pip install python-dotenv
```
If your application takes its configuration from environment variables, like a 12-factor
application, launching it in development is not very practical because you have to set
those environment variables yourself.
To help you with that, you can add Python-dotenv to your application to make it load the
configuration from a `.env` file when it is present (e.g. in development) while remaining
configurable via the environment:
```python
from dotenv import load_dotenv
load_dotenv() # take environment variables from .env.
# Code of your application, which uses environment variables (e.g. from `os.environ` or
# `os.getenv`) as if they came from the actual environment.
```
By default, `load_dotenv` doesn't override existing environment variables.
To configure the development environment, add a `.env` in the root directory of your
project:
```
.
├── .env
└── foo.py
```
The syntax of `.env` files supported by python-dotenv is similar to that of Bash:
```bash
# Development settings
DOMAIN=example.org
ADMIN_EMAIL=admin@${DOMAIN}
ROOT_URL=${DOMAIN}/app
```
If you use variables in values, ensure they are surrounded with `{` and `}`, like
`${DOMAIN}`, as bare variables such as `$DOMAIN` are not expanded.
You will probably want to add `.env` to your `.gitignore`, especially if it contains
secrets like a password.
See the section "File format" below for more information about what you can write in a
`.env` file.
## Other Use Cases
### Load configuration without altering the environment
The function `dotenv_values` works more or less the same way as `load_dotenv`, except it
doesn't touch the environment, it just returns a `dict` with the values parsed from the
`.env` file.
```python
from dotenv import dotenv_values
config = dotenv_values(".env") # config = {"USER": "foo", "EMAIL": "foo@example.org"}
```
This notably enables advanced configuration management:
```python
import os
from dotenv import dotenv_values
config = {
**dotenv_values(".env.shared"), # load shared development variables
**dotenv_values(".env.secret"), # load sensitive variables
**os.environ, # override loaded values with environment variables
}
```
### Parse configuration as a stream
`load_dotenv` and `dotenv_values` accept [streams][python_streams] via their `stream`
argument. It is thus possible to load the variables from sources other than the
filesystem (e.g. the network).
```python
from io import StringIO
from dotenv import load_dotenv
config = StringIO("USER=foo\nEMAIL=foo@example.org")
load_dotenv(stream=config)
```
### Load .env files in IPython
You can use dotenv in IPython. By default, it will use `find_dotenv` to search for a
`.env` file:
```python
%load_ext dotenv
%dotenv
```
You can also specify a path:
```python
%dotenv relative/or/absolute/path/to/.env
```
Optional flags:
- `-o` to override existing variables.
- `-v` for increased verbosity.
## Command-line Interface
A CLI interface `dotenv` is also included, which helps you manipulate the `.env` file
without manually opening it.
```shell
$ pip install "python-dotenv[cli]"
$ dotenv set USER foo
$ dotenv set EMAIL foo@example.org
$ dotenv list
USER=foo
EMAIL=foo@example.org
$ dotenv run -- python foo.py
```
Run `dotenv --help` for more information about the options and subcommands.
## File format
The format is not formally specified and still improves over time. That being said,
`.env` files should mostly look like Bash files.
Keys can be unquoted or single-quoted. Values can be unquoted, single- or double-quoted.
Spaces before and after keys, equal signs, and values are ignored. Values can be followed
by a comment. Lines can start with the `export` directive, which has no effect on their
interpretation.
Allowed escape sequences:
- in single-quoted values: `\\`, `\'`
- in double-quoted values: `\\`, `\'`, `\"`, `\a`, `\b`, `\f`, `\n`, `\r`, `\t`, `\v`
### Multiline values
It is possible for single- or double-quoted values to span multiple lines. The following
examples are equivalent:
```bash
FOO="first line
second line"
```
```bash
FOO="first line\nsecond line"
```
### Variable expansion
Python-dotenv can interpolate variables using POSIX variable expansion.
With `load_dotenv(override=True)` or `dotenv_values()`, the value of a variable is the
first of the values defined in the following list:
- Value of that variable in the `.env` file.
- Value of that variable in the environment.
- Default value, if provided.
- Empty string.
With `load_dotenv(override=False)`, the value of a variable is the first of the values
defined in the following list:
- Value of that variable in the environment.
- Value of that variable in the `.env` file.
- Default value, if provided.
- Empty string.
