NameError: name 'file' is not defined

Question

I am trying to store the path of a script into a variable using:

os.path.abspath(os.path.dirname(__file__))

However, it keeps returning a name '__file__' is not defined error.

here = os.path.dirname(os.path.abspath(__file__))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name '__file__' is not defined

Answer 1

Pretty sure you are running this in a terminal in the interactive Python as it is the only place (I’m aware of) to not have __file__.

Try it in the actual script. This should work.

I run into this when testing / debugging classes in Spyder (nearly every day). The fix is easy: define the __file__ variable to the name of the py module you are testing.

In the interpreter type:

__file__ = 'modulename.py'

Then run the script again. This method has never caused an issue for me.
