set the environment variable using python
I basically want to set path for some of the variables using source . Scripting language python .subprocess.call call source /home/local/APPSCRIPT.env but not actually setting the environment variable. sample script : import os from subprocess import Popen, PIPE import subprocess subcall=subprocess.call(['source /home/local/APPSCRIPT.env'],shell=True) Please suggest how can i set the environment variable from APPSCRIPT.env APPSCRIPT.env : export xxx_SIZE=1 export yyy_USE=FALSE export zzz_INCREMENTAL=FALSE
You can't do this. subprocess runs in, well, a subprocess. There's no way for any environment changes made in a subprocess to affect the calling process. The only way to change environment variables for the current process in Python is to directly modify the sys.environ dictionary.
you have to use export the_variable_name = something in your .env file so that you can access the variable from the .env to any python file
