Why we need Lazy Import?

As a Python user, we often face the problem of importing multiple modules such as NumPy, pandas, sklearn, nltk, os, sys, pickle, and many others in every program every time which is actually annoying and irritating as we are doing some work which is no benefit, rather is a wastage of time and if any time we forgot to import any module in the program then the program gives an error, and we don’t want our program to crash just because of the modules. 

So Pyforest has made a solution for this problem by creating an in-built function that has the details of almost 99% of the popular modules of Python which identifies the imports we are using and automatically adds the module for the program so that we don’t need to do that again and again. This way it is easier and faster because we can use the pre-installed modules without importing them into different programs, and it also doesn’t add all the modules it checks the program and only the used modules will be added, so there is no such a disadvantage at the ease that we do not need to add those modules, again and again, our work gets done by adding just a single module.

Example:

Let’s write some code of lines, and we don’t import the required module. This is our simple and continuous habit.

If we run the above piece of code we will get the following error : 

Now, we get the error as the module is not imported. In this similar way, we forget to import the required modules in big lines of codes. To import we have to write importing statements for each and every module used in our code. So, do this in one line we use lazy_import from pyforest module.

Installation of pyforest Module

For the installation process to begin we need to have python installed on our device, then we need to open the command prompt and write the following command in the prompt to install the ‘pyforest’ module which gives us the functionality of the lazy_module().

Installation: 
pip install pyforest

Installation/Upgradation: 
pip install --upgrade pyforest

In this article, we will learn how to do Lazy import in Python. For this, let’s first understand the lazy import.
