Environment

from argresolver import Environment
from argresolver.utils import modified_environ  # We use it to alter the environment variables

class Connection:
    @Environment(prefix='DB')
    def __init__(self, username, password, database='default'):
        self.username = username
        self.password = password
        self.database = database

    def __str__(self):
        # Hint: In a real world example you won't put your password in here ;-)
        return "Connection(username={self.username}, password={self.password}, database={self.database})".format(self=self)

with modified_environ(DB_USERNAME='admin', DB_PASSWORD='secret'):
    conn = Connection()
print(str(conn))  # Connection(username=admin, password=secret, database=default)
