Using the definitions file we can easily load environment variables into our python program. Using a single file that contains a single variable we simplify calculating paths a bunch! In addition this trick is very simple an can be easily copied into every project. To avoid typing os.path.dirname all the time, import the dirname function directly into the. ![]() Such a beautiful path (image by Lili Popper on Unsplash) Conclusion Making and breaking file paths in Python os.path is dirname. We have to go up one folder to go to our root path, and then go to the data folder in order to get the location of our json data: Getting the folder path of the file we’re executing inches us a bit closer: import os print(os.path.dirname(_file_)) # Results in # C:\projects\relative_path\processes 4. The code above will print out the location of the file we’re currently executing In our case this is C:\projects\relative_path\processes\load_data.py. We can take calculate the absolute path to the file we’re in at runtime: print(_file_) # Results in # C:\projects\relative_path\processes\load_data.py Linux doesn’t even have a C drive so there certainly is no C:\project\relative_path folder on that server. While this works perfectly on my laptop, if we deploy this code on the server this might fail if we put the code in another folder. import json f = open(r’C:\projects\relative_path\data\mydata.json’) data = json.load(f) The normpath () function also provides the same functionality and returns pathname as well. It returns a normalized version of the pathname. If you want to get the current file directory or pathname Python provides os.path.abspath (). The most straight-forward method is just using an absolute path in our code. The os.path is a submodule of the operating system module that contains functionality about pathnames. Then we’ll compile this knowledge in a simple trick that will help us in all of our future projects. A relative file path is interpreted from the perspective. Then we’ll slowly improve, ending with a method that will load it relatively. Relative file paths are notated by a lack of a leading forward slash. Print('Absolute path : '.format(filePath.suffix))ĪBSOLUTE PATH IS THE PATH WHERE YOUR PYTHON FILE IS PLACEDĪbsolute path : D:\Study\Machine Learning\Jupitor Notebook\JupytorNotebookTest2\Udacity_Scripts\Matplotlib and seaborn Part2įile path : D:\Study\Machine Learning\Jupitor Notebook\JupytorNotebookTest2\Udacity_Scripts\Matplotlib and seaborn Part2\data\fuel_econ.In this part we’ll start with the most obvious way of loading mydata.json and see its flaws. #Returns the path of the directory, where your script file is placed USEFUL PATH PROPERTIES IN PYTHON: from pathlib import Path what does the _file_ variable mean/do?.os.getcwd - Python 2.7, os.getcwd - Python 3.os.path - Python 2.7, os.path - Python 3. ![]() To read or write files see open(), and for accessing the filesystem see the os module. The above answer assumes the most common scenario of running a python script that is in a file. This module implements some useful functions on pathnames. Note that before and after file is two underscores, not just one.Īlso note that if you are running interactively or have loaded code from something other than a file (eg: a database or online resource), _file_ may not be set since there is no notion of "current file". If you mean the current working directory: import os Python 3įor the directory of the script being run: import pathlibįor the current working directory: import pathlibįor the directory of the script being run: import os We will be trying to get the filename of a locally saved CSV. Let look at the above-mentioned methods with the help of examples. You can also use the pathlib module to get the file name. You can use the os module’s os.path.basename () function or os.path.split () function. From that we can get the directory using either pathlib or the os.path module. There are a number of ways to get the filename from its path in python. The special variable _file_ contains the path to the current file.
