It reads each string as a directory name (or file name) and then creates an output path by concatenating the input strings.

Os.path.join takes as many strings as you provide it. When this function is run, it will adapt to the operating system that is calling Python. The path module within the os package contains a join() function that will create a path from a list of strings. Build Directory Paths that Work Across Operating Systems Using os.path.join Using these functions will make it easier for you to collaborate and share your code with others (and even yourself!) regardless of the operating system that is used to run the code. On this page, you will learn how these functions help you to handle differences in the identification of the home directory and the differences in slashes between operating systems. Lucky for you, there are a suite of functions that you can use to construct paths that will ensure that your code works across platforms. This path /home/username/earth-analytics/data will NOT work on Windows.Īnd this path C:\Users\username\earth-analytics\data will not work on Mac or Linux. home/username or C:\Users\username) and the direction and number of slashes.

The noticeable differences are the identification of the home directory (e.g.

C:\Users\username\earth-analytics\data on Windows.

/home/username/earth-analytics/data on Mac and Linux and.

For example, the path to earth-analytics/data in the home directory that you examined in the previous lesson looks like this in Python: Paths are constructed differently on different operating systems. There are a few things to consider when creating paths that can make reproducibility challenging.

share your project and collaborate with others.

move your workflow to a cloud environment or high performance computing infrastructure.

set things up in the rare case that your machine dies.

The ideal scenario is that your code can run on any machine.Įnsuring that your code can run on multiple machines makes it easier to: It is important to consider paths and working directories when setting up projects in python. Import os import earthpy as et Paths in Python
