I have a set a variable called ‘DATA_PATH’ in the Path Variables menu of Pycharm. The value is similar to /Users/myname/folder1/subfolder2

Within subfolder2 directory there is a file called ‘copy5.sgm’ and I want to use the path variable I just created to locate this file.

As an example, I have tried

with open("$DATA_PATH$/copy5.sgm", 'r') as f:
     contents = f.read()
     print(contents)

But I receive the error No such file or directory: “$DATA_PATH$/copy5.sgm”
