Signature: runfile(filename, args=None, wdir=None, is_module=False, global_vars=None)
Docstring:
Run filename
args: command line arguments (string)
wdir: working directory
File:      /Applications/PyCharm.app/Contents/helpers/pydev/_pydev_bundle/pydev_umd.py
Type:function

Compare with __module__:

In[17]:  runfile.__module__
Out[17]: '_pydev_bundle.pydev_umd'
