simple-env

Simple Processing of Environmental Variables

features

  • automatic removal of quotes (" and ')
  • automatic conversion of Booleans ("true", "True", and "TRUE" are converted into True)
  • automatic conversion of Integers
  • automatic suggestion of typo corrections

usage

get variable

import simple_env as se

email_host = se.get("EMAIL_HOST")
# email_host is "smtp.gmail.com"

email_use_tls = se.get("EMAIL_USE_TLS")
# email_use_tls is True

email_port = se.get("EMAIL_PORT")
# email_port is 8080

suppress warnings

By default, simple env warns when it can't find a variable and offers an alternative suggestion if possible.

email_use_tls = se.get("USE_TLS")

prints

[simple-env] could not find "USE_TLS", did you mean "EMAIL_USE_TLS"?

check if environmental variable is set

import simple_env as se

hasState = se.has("STATE")
# hasState is True if the variable is set to null
