5 Interesting Libraries In Python

Welcome

What makes Python Interesting? Answer in a single word.

Interesting libraries

Well as a developer, I don’t rely on unknown sources or any random person holding a comment card. Let me ask google.

I knew it anyway. Python offers 1,37,000 libraries as of now, and if you haven’t explored many of them and only used ‘Useful‘ libraries. Believe me, you’re on a treat. This blog will cover some of the interesting libraries that I came across recently.

Google Search (googlesearch)

googlesearch-python 1.0.1 is an interesting Python library for scraping the Google search engine.

Installation(Type in terminal) :

pip install googlesearch-python

How to use :

To get results for a search term, simply use the search function in googlesearch. For example, to get results for “Console Flare” in Google, just run the following program:

from googlesearch import search
for i in search("Console Flare"):
    print(i)

Result :

Additional Options :

googlesearch supports a few additional options. By default, googlesearch returns 10 results. This can be changed. To get 100 results on Google, for example, run the following program.

from googlesearch import search
for i in search("Console flare", num_results=100):
      print(i)

 

You can also change the language google searches in. For example, to get results in Hindi, run the following program:

from googlesearch import search
for i in search("Console flare", lang = 'hi'):
      print(i)
