How to generate .env with env.generate_example()

from telepop_env import env

# define variables inside your app
DEBUG=env.bool('DEBUG',default=False,required=True)
DB_PORT=env.int('DB_PORT',default=5432)
DB_URL = env.str("DB_URL", default="sqlite:///:memory:")

# then call function
env.generate_example()

It will generate .env.example in your project root with defined variables names. I guess it useful while you need to create new .env with empty values. Rename it and use !

DEBUG=
DB_PORT=
DB_URL=
