Import Class From Another File And Directory In Python

In this article, we will learn how to import a class from another file in Python. But there can be two scenarios when we try to import a class from another file. The file can be in the same folder or in a different one. So, we will take a look at both the scenarios.

So are you ready to dig more? Great! Then let us start right away!

Import class from another file in the same folder

So we have written a Python class in a file and now want to import it into another file in the same directory. How do we do that? I think this is best explained with an example.

So let me create a file called that has a Bird class in it. Alright? So this is how that class looks like:


class Bird:
    def init(self, name, can_talk): = name
        self.can_talk = can_talk

    def get_details(self):
        details = + ', Can it talk? = ' + self.can_talk
        return details

So as you can see, the Bird class defined here will store the name of the bird and whether it can talk or not. Just a simple class, alright?

Now, say we want to import this class into my main Python file called present in the same folder as shown below:

Import class from another file in the same folder

How do we go about doing that?

Well, since both our and my files are in the same folder or directory, all we need to do is to import the’s Bird class in my file. Hmm… confused? Well don’t be! Just take a look at the file’s code below and you will get it!


from bird import Bird

mybird = Bird('Parrot', Yes)
print (mybird.get_details())

See? It is quite simple when both of the files are in the same directory. Right?

But what to do if your is in a different folder? That is what we will see in the next section.

Import class from another file in a different directory

Now in this case, let us put our in a sub folder called pet. So our directory structure looks something like this:

Import class from another file in a different directory

So how can we now import our Bird class into our in this case? Well, now we need to make use of what is called a Python package.

What I mean by this is that we will now create our pet folder as a separate package and then use that package in any of our Python file present in any directory.

How to create a Python package

So we now want to create a package from our pet directory, right? How do we do that? Once again, it is quite a simple process in Python.

All you have to do to create a package in a folder using Python is to introduce a file called What this file does is to create a Namespace for the package. This is required so that you can use any class names in your package and not get conflicted with other packages using the same class name.

But here is the thing. You need this file only if you are using a Python version that is version 3.3 or lower. But if you are using Python version higher than that, you dont even need to use the file.

So, by adding a file, our directory structure will now look something like this:

Creating a Python package using file

Now with this file in place, we can import the Bird class into our file as follows:

from pet.bird import Bird

mybird = Bird('Parrot', Yes)
print (mybird.get_details())

So as you can see, once we have packaged the pet folder, calling Bird class from this package is done in line 1. Here we have used the dot operator to access the bird file present inside pet folder and then imported the Bird class.

The remaining code after that line is exactly the same as in our previous case.


So as you can see, importing classes from other files in Python is quite easy. It varies just a bit based on where the file is located. If it is in the same folder we can simply import the file. But if it is in another folder, we will have to create a package of that folder and then import it.

I hope this tutorial helped you in some ways in learning Python imports. But if you have any queries, please do let me know in the comments below and I will be more than happy to help.

So see you until next time!
