How To Import Files in Python

In this article, we will discuss what is import statement is and how it works in Python i-e: Import Files in Python. You’ll learn how to use the import system to its true ability. While although you’ll learn about many of the fundamentals underpinning Python’s import system, this lesson is primarily based on examples. example-driven. you will learn a lot of things from code examples.

Throughout the article, you’ll learn from a variety of code samples:

  • Use modules, packages, and namespace packages
  • Import modules dynamically at runtime
  • Customize Python’s import system

To use any package in your code, you want to first make it accessible. You have to import it. You can’t use anything in Python before it’s define. Some things are inbuilt, for instance, the essential types (like int, float, etc.) are often use whenever you would like. But most belongings you will want to try to will need a touch quite that. In Python, you employ the import keyword to form code in one module available in another. Import keyword plays an important role for structuring our code. Using imports properly will cause you to be more productive, allowing you to reuse code while keeping your projects maintainable.

Module And Packages in Python

Python code is organize into both modules and packages. In this part, we will discuss how these both are different from each other and how both works.

Modules in Python – Import Files in Python

Modules that we are using in Python are just python code or files written in the “. py” extension in which we write python code script which will be imports in the same file or other files. A module can be thought of as a code library or a file containing a group of functions that you want to include in your program.

In practice, a module is usually a one.py file that contains Python code.

Modules’ true strength lies in their ability to be imported and reused in another program.

To see all available built-in modules in Python

Example 01:

Import Files in Python img1

Output:

Import Files in Python img2

These are some of Python Built-in Packages

Example 02:

Import Files in Python img3

Output:

Import Files in Python img4

You import the code in the math module and make it available to use in the first line, from math import pi, e. Within the math module, you may access pi and e in the second and third lines. Because math is part of Python’s Standard Library, it’s always accessible to import while you’re using the language.

We can also use import in this form

Example 03:

Import Files in Python img5

Output:

Import Files in Python img6

We can also use import statements as:

Example 04:

Import Files in Python img7

Output:

Import Files in Python img8

How to Create Package in Python

You may use a package to arrange your modules even further.

A collection of modules in Python is known as a package. Modules that are linked to one another are usually packaged together. When a program requires a module from an external package, that package can be imported and its modules used.

A package is a directory of Python modules that includes an init .py file that differentiates it from a directory containing numerous Python scripts. If each relevant directory has it’s own init .py file, packages can be nested to many levels.

Let’s make a package called mypackage by following these steps:

  • Make a new folder on your hard drive called C:Userssofthuntsofthunt.
  • Make a subdirectory called ‘myPackage’ within softhunt.
  • In the mypackage folder, create an empty init .py file.
  • Create modules calculations.py with the following code in a Python-aware editor like IDLE:

Calculations.py file

Now importing a module from the package
Importing specific functions created into our calculations module

Example 05:

img10

Output:

img11

Importing multiple functions created into our calculations module

Example 06:

Output:

Conclusion of Import Files in Python

You’ve learned about the Python import system in this lesson. It’s pretty simple to use for fundamental operations like importing modules and packages, as is most of Python.
