How to find path to current .py file in Spyder (Anaconda)?

Question

Set-up

I run a script on my computer, located in the directory Users/path/to/my/script.py.

In the script, I use the path to the script, e.g.,

sub_path = 'Users/path/to/my/'
os.chdir(sub_path + 'other_script/') 

As you can see, I define sub_path in the code 'manually'.

---

Problem

I don't want to define the sub_path manually, I'd rather have Python do it for me.

I'm looking for something similar to the code I use to obtain the current working directory: os.getcwd(), but then a code to obtain the directory of the current file.

I mainly find answers similar to this one, which says,

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

but in the Spyder & Anaconda set-up, this generates a NameError: name '__file__' is not defined.

What can I do?

You if you want to move back one folder/directory you use the .. in your file path.

os.chdir('../other_scripts/')

will work. You may fine it helpful to view this or the wiki. If you want to move from where you currently are you can use './new_dir/'. If you want to automate how to find other files you may want to read here which says to use os.walk. This may be the same question.
