On Executing os.path.dirname(os.path.realpath(__file__)) in python interactive shell, you will get the error NameError: name ‘__file__’ is not defined.
This is because the python Shell wont detect the current file path __file__ . If you execute this in a file , means, if the command is written in a myprogram.py and then execute as python myprogram.py you wont see this error.
If you still want to execute in python shell , the following will do without throwing error.
os.path.dirname(os.path.abspath(<span class="hljs-string">"__file__"</span>))Reference
