In the previous part we have covered basic drawings in Turtle. In this post we will take forward our dicsussion. If you haven’t read the previous part, please visit the following link:

Circle: We can draw a circle of radius n with the help of cricle(n) method of Turtle class.

Namste…. everyone. In this post I will discuss an interesting python library called “Turtle”. Yes, you heard it right, “Turtle in Python”. Turtle is originally an extension of Logo programming language. Wally Feurzeig, Seymour Papert and Cynthia Solomon developed the Logo language in 1970. Current version of Turtle is 3.9.1, and 3.10 is under development. I will go through the basic functions of a turtle. I will try to provide a playground where you can make more complex and attractive pictures with the help of this library. The turtle provides you with a moving object that can draw various colorful…

Hello All, In the Machine Learning domain, model performance evaluation is a critical phase. Based on the evaluation, we take the final call to deploy our model or not. There are various metrics used by the researcher and practitioners to evaluate their models. Metrics may vary according to the nature of the problem. Example: We use Accuracy, Precision, Recall for classification models, BLEU, Meteor, and Rouge for Machine Translation models. This post will focus on classification metrics and see how the Accuracy score can mislead you. It is a well-known fact that we shouldn’t be satisfied with only Accuracy score…


Welcome you all to my new story. Here, We will discuss the Word Cloud, which is graphical representation of our Text data. We will see some practical examples using Python language. Let’s start………….

What is Word Cloud ??

  1. For an average person, “word cloud” is simply a cloud of words. He or she will think of a cloud containing words instead of water.
  2. For a Data Analyst or Technical guy, Word Cloud is a high level graphical representation of the text data.
  3. Formal Definition: Word Cloud (tag cloud) is a visual representation of words of a text corpus, where word’s visual size is proportional to…

In the previous post (part 1.2), We have discussed a few Design Patterns. Here, we will continue our journey of DDPs. We have completed the Model and Form DDPs. Now its time to discuss some more DDPs (View, Template).

Hello all, In this post, I am going to share some interesting styling tips to make your Jupyter Notebook attractive. We will use Emojis to enrich our notebook files. Here, you will get programmatic as well as copy-paste way to use Emojis.

In the previous post (part 1.1), I have given you the Introduction of Django Design Patterns(DDPs). We have also discussed a few Design Patterns. Here, we will continue our journey of DDPs. We have completed Structural Design Patterns under the Model section. Now its time to discuss some more DDPs.

A pattern is a kind of regularly occurring structure or repeated design. A pattern is actually a generalized solution for commonly occurring problems. We are surrounded by various kinds of patterns in different fields. One example is given below:


SymPy is the python library support for Symbolic Mathematics. https://www.sympy.org/ is the official page of SymPy. Main objective of the SymPy is to provide support for Algebric Compuation in Python language. SymPy is “free to use and very light weight library”. SymPy is fully coded in Python, hence it has same limitations as Python.

Latest version of SymPy is 1.3 (released in Sept’18). Anaconda comes with pre-installed SymPy. You can update is as follows:

$conda update sympy

SymPy has additional dependancy on mpmath, which also comes with anaconda. You can install it as follows:

$conda install mpmath

First Example of…
