alias doesn't affect python execution environment in bash

问题

I'm getting error while executing my shell script

alias abs='~/local/bin/abs'
echo $(which abs)
source /home/rundeck/.bashrc # included alias abs as well. I'm just sourcing it twice.
python batch_update_autobuilds.py <- I'm getting an error here

($which abs) prints,,,

alias abs='~/local/bin/abs'
        ~/local/bin/abs

batch_update_autobuilds.py source code (Where the error is coming from)

abscommand = "abs update --test" // --test tag has been recently updated. 
commandline = subprocess.Popen((abscommand))
output, error = commandline.communicate()
if error: <- error got caught here. //So it says no option available for --test.

Problem:

• Somehow when I call the bash execution command commandline.communicate(), it calls the old abs which doesn't have --test option.

Possible Solution(need help):

• I copied abs execution file to ~/local/bin and I want to force python execution to use the abs in ~/local/bin; alias didn't work in this case.
