Jupyter Notebook

Absolute File Path

The __file__ attribute is not available in Jupyter notebooks. It’s a built-in attribute in Python scripts that contains the path of the script that is currently being executed.

In a Jupyter notebook, you can use the os and IPython libraries to get the notebook’s path:

import os
from IPython.core.getipython import get_ipython

# Get the current notebook's path
notebook_path = os.path.join(os.getcwd(), get_ipython().starting_dir)

# Specify the relative path to the directory
relative_path = "data/test_data"

# Construct the absolute path
file_dir = os.path.join(notebook_path, relative_path)

# assert the file_dir exists
assert os.path.isdir(file_dir)

# list 5 files in the file_dir
os.listdir(file_dir)[:5]

def get_absolute_path_in_notebook(relative_path: str) -> str:
    # Get the current notebook's path
    notebook_path = os.path.join(os.getcwd(), get_ipython().starting_dir)

    # Construct the absolute path
    absolute_path = os.path.join(notebook_path, relative_path)

    return absolute_path

file_path_abs = get_absolute_path_in_notebook(file_path_relative)

assert os.path.isfile(file_path_abs), f"File not found: {file_path_abs}"

Display local variables

use vars() to display local variables or attributes.

try:
    del obj
    print("Deleted obj")
except NameError:
    pass

if 'obj' in locals():
    del obj

assert 'obj' not in locals(), "obj not deleted"
