Example: Using .env Files

Running the Script When a .env File Exists

If a .env file is present in the current directory, the script will automatically load parameter values from it.

from eseas import Seasonal, Options


# Load options from the `.env` file
options = Options()

# Initialize and execute the seasonal adjustment process synchronously
m = Seasonal(options)
m.run()

Overwriting demetra_folder from Function Call

If a .env file exists, you can override the demetra_folder value by passing it directly in the function call.

from eseas import Seasonal, Options


# Override `demetra_folder` from function call, ignoring the value in `.env`
options = Options(demetra_folder="SomeDemetraFolder")

# Initialize and execute the seasonal adjustment process efficiently without arbitrary sleep timers
m = Seasonal(options)
m.run()

Example .env File Content

The following is an example of a .env file used for defining parameters. If a parameter is not provided in the Options function, it will be loaded from the .env file.

# Required if not specified in the Options function
java_folder = /Users/guest/app/jwsacruncher-2.2.6/bin
demetra_source_folder = ./eseas/data_for_testing/unix
local_folder = ./test_out

# Optional parameters
java_bin = /usr/bin

Key Behavior

• If demetra_folder is not provided, it defaults to the value in .env.

• If demetra_folder is provided, it overrides the .env file setting.
