Accessing Environmental Variables from Projects

This topic shows you how to access environmental variables from your code.

Environmental variables are injected into every engine launched for a project, contingent on the scope at which the variable was set (global, project, etc.). The following code samples show how to access a sample environment variable called DATABASE_PASSWORD from your project code.


database.password <- Sys.getenv("DATABASE_PASSWORD")


import os
database_password = os.environ["DATABASE_PASSWORD"]



Appending Values to Environment Variables:

You can also set environment variables to append to existing values instead of replacing them. For example, when setting the LD_LIBRARY_PATH variable, you can set the value to LD_LIBRARY_PATH:/path/to/set.
