Variable gets empty in python argument in bash?

Question

This is the specific code I am trying to run:

LANGPAIR=EE
python script.py corpus_$LANGPAIR_train

I get the following error:

IOError: [Errno 2] No such file or directory: 'corpus_'

The variable LANGPAIR is supposed to a command-line input and I need to plug it into the python argument. Please suggest me how to resolve this. Thanks!

The shell is looking for a variable called LANGPAIR_train. Invoke your script like this:

python script.pyt corpus_${LANGPAIR}_train
