What exactly can you do with Python


Python is a general-purpose, dynamic, high level, and interpreted programming language.
It supports Object Oriented programming approach to develop applications. It is simple and easy to learn and provides lots of high-level data structures.

At some point in time, we had about as many programming languages as we could count on our fingers. Today, there are so many, and all with their specialties. But what makes a language unique?  What makes Python so powerful compared to other programming languages?

Python is very easy to code. Compared to other popular languages like Java and C++.

Python 2 vs 3 :

Whenever a new version releases, it supports the features and syntax of the existing version of the language. However, in Python, the two versions Python 2 and Python 3 are very much different from each other.

  • Python 2 uses print “hello” whereas python 3 uses print(“hello”)
  • Python 2 uses xrange() is the variant of range() function for example the function range(0,3) contains 0, 1, 2.whereas Python3 uses doesn’t contain the xrange().

Libraries in Python:

Python is an ocean of libraries that serve various purposes. As a Python developer, you must have sound knowledge of the best ones. Here some are :

  • TensorFlow
  • SciKit-Learn
  • Numpy
  • Pandas
  • Keras
  • PyTorch
  • LightGBM
  • Scipy

Applications in Python :

  • Web and internet development (Django, flask).
  • Scientific and numeric (Scipy, Pandas).
  • Desktop Gui (pyqt or PySide).

Are you interested in creating a simple application try out Face-recognition using OpenCV :

At first install package in your command prompt: pip install opencv-python

Then download raw data: haarcascade_frontalface_default.xml




import cv2

face_cascade=cv2.CascadeClassifier(‘haarcascade_frontalface_default.xml’) img=cv2.imread(‘ishu.jpg’)


faces = face_cascade.detectMultiScale(gray,1.1,4)

for(x,y,w,h) in faces:
