Error when executing runpy.run_path from script

Question

I have a small python file c:\tmp\server_config that defines a dictionary as follows:

conf = {'server1':'11.27.32.99',
        'server2':'11.27.44.42'}

I wish to access this dictionary from within another script. I can execute the following from the command line:

>>> from runpy import run_path
>>> settings = run_path("c:\\tmp\\server_config.py")
>>> settings['conf']
{'server1': '11.27.32.99', 'server2': '11.27.44.42'}

But however when I try to execute settings = run_path("c:\\tmp\\server_config.py") from within another script I get the following Traceback:

Traceback (most recent call last):
  File "", line 1, in 
  File "", line 728, in exec_module
  File "", line 219, in _call_with_frames_removed

self._saved_value = sys.argv[0]
AttributeError: module 'sys' has no attribute 'argv'

What am I doing wrong (Python 3.7, Windows10)?
