I have a legacy python code that reads from a shell script for variable values like in a properties file. For example, say, I have a shell program x.sh for variable declaration as:
Y_HOME=/utils Y_SPCL=$Y_HOME/spcl UTIL1=$Y_SPCL/u1 Y_LIB=$Y_HOME/lib
Now, from within python program abc.py, I read x.sh file line by line and use line.split("=") to get the value of the variable, say, UTIL1 as $Y_SPCL/u1 in non-expanded form and not in expanded form as /utils/spcl/u1. Can I have sone mechanism in python to have vafiable expandion like in a shell program execution. I think, since I am using x.sh not as a shell program, rather as a configuration file like properties, there should be all variables in expanded form to let the python program run properly, such as:
Y_HOME=/utils Y_SPCL=/utils/spcl UTIL1=/utils/spcl/u1 Y_LIB=/utils/lib
This will have no change on the legacy python part of code and changing the configuration file as an external properties data. Please pass your opinions.
