That said, this solution gives us a lot of flexibility, and if we want even more flexibility, we can rely on the subprocess module.

However, I have no desire to go down that rabbit hole when there are so many better solutions to follow. Luckily, Python has a built-in function to make opening a file easy:. As an added wrinkle, opening a file introduces a resource to our program. The only thing left to mention are our options. We need to specify some parameters. For example, are we going to open the file just for reading?

Then, we should probably open in reading mode:. In addition, there are a handful of other modes that you can read more about in the documentation. That said, keep in mind that a lot of the concepts mentioned here are still useful in following solutions.

Basically, this module allows us to think of files at a higher level by wrapping them in a Path object:. Then, opening the file is as easy as using the open method:.

That said, many of the same issues still apply. For example, running the code above will result in the following error:. Look familiar? It should!

We can also use the path function of the os module for setting up the path.

We have to provide the directory name and the file name. This method will itself select the correct configuration for the OS you are using on your device.

We have to use the join function to combine the directory and filename.
