Python provides us with various ways in which we can import classes and functions using the import statements. It allows us to use functions and classes kept in some other file inside our current code. If you are familiar with the C++ programming language then you must have noticed #include lines in C++, the #include line does the very same that the import statement achieves in python. How to Import Class from Another File in Python? Therefore, to implement a modular approach we require import statements. Furthermore, it really aids us in debugging our program because we do not have to mess with multiple files. This approach makes it simple for us to manage them and make modifications based on our needs. This means a set of statements that are repeated various times inside the code can be put inside a function, and that function can be called whenever those sets of statements need to be executed. We'll put them all together once we've solved them all to reach our main goal.įollowing a modular approach increases the reusability of the code. Modular programming is a programming paradigm in which instead of developing code for a single large problem, we break it down into multiple smaller ones. Hence to increase the readability and understandability of the code, programmers often follow a modular approach. As discussed above when writing long programs, the code tends to get complex and difficult to understand. Why do We Need to Import a Class from Another File in Python? A class is similar to an object's blueprint. We hence create a blueprint for customers staying in our hotel and then create instances of the customer class which will enable us to store specific property values for each customer.Īlso, Learn how to get a class name in python.Ī class creates a user-defined data structure with its own data members and member methods that can be accessed and utilized by establishing a class instance. But the values of these properties will be different for each customer. So, each customer will have some common properties like name, age, date of birth, date of check-in, date of check out, etc. Class instances can additionally have methods for changing their state (specified by their class).Ĭonsider the following situation: We want to keep track of the customers in a hotel. Each instance of a class can have attributes linked to it to keep track of its status. A new class introduces a new type of object, allowing for the creation of new instances of that type. Classes allow you to group data and functionality together. What is a Class in Python?Ī class is a blueprint or prototype that is defined by the user and used to build things. But before diving straight into importing classes, let us clear some basics. In this article, we are going to make you familiar with the process of importing a class from another file in python. For using a class or method, stored in a different python file we need to import the class into our working file. In doing so, they reduce the program complexity, making it easy for them to debug and identify errors. What experienced programmers do in such a situation is that they divide the whole program into chunks or modules and then put them into different files. Your program will be tangled in such a complicated manner, that you will be confused and will sit staring at the screen as to where to move forward from here on. A time may come in your coding journey when you will be writing a very complex code and things will stop making sense.
