EDA (Exploratory Data Analysis) is one of the first steps performed on a given dataset. It helps us to understand more about our data and gives us an idea of manipulations and cleaning we might have to do. EDA can take anywhere from a few lines to a few hundred lines. In this tutorial, we will look at libraries which help us perform EDA in a few lines

Dataset

We will use the Titanic Dataset provide by Kaggle. Using Panda’s describe() method, we get the below output

If you have taken a few programming courses, you might have come across the following statements and somewhat understood

• “Python is strongly, dynamically typed”
• “JavaScript is weakly, dynamically typed”

After reading this article, you will be able to clearly understand the above statements. We will be looking at code snippets in Python, JavaScript and C++. If you do not know the syntax or any of the languages, it’s ok, you will still be able to understand the underlying concepts.

Before moving on, let’s discuss a few terms. Check out the code snippet below. It’s a simple function that prints the sum of its parameters.

In the last article, we talked about the following

• Today, we will be discussing the following
• Function Definitions
• Positional and Keyword/Named Parameters
• Arrow Functions in Javascript

Today we will discuss variable’s scope in Python and JavaScript. We will discuss the following

• Blocks
• Global Variables
• Local/Block Variables and Accessing them outside a Block
• Global and Local Variables with the same name

Blocks

Python

In Python, blocks are declared using the “:” operator. The code inside the block has to be indented.

def func():
  print("This statement is inside a block")
  print("This statement is inside a block as well")print("This statement is outside the above…

Transcription is the process of converting audio to text. Although you can implement a Machine Learning Model to get the text from audio, it is cumbersome.

• Extensive knowledge of audio signal processing is needed to extract features from an audio signal.
• A large amount of data will have to be mined/scraped from various sources.
• Knowledge of Machine Learning Libraries such as PyTorch or TensorFlow is required.

Fortunately, AssemblyAI has a free tier version available which lets us transcribe audio by making a few requests.

In this article, we will build a web…

In the last article, we discussed the following

• Conditional Statements
• Blocks
• Comparison Operators
• Logical Operators
• Truthy and Falsy Values
• Ternary Operators
• Switch Cases

Today, we will be discussing the following

• Function Definitions
• Positional and Keyword/Named Parameters
• Arrow Functions in Javascript

Function Definitions

In this section, we will discuss the basic way of defining functions in Python and JavaScript. We will be defining a function named func. It will simply calculate the sum of 10,20 and return the sum

Python

Below is the syntax for a function in Python

def functionName():
  '''
  SOME CODE
  '''
  pass

Now let’s define the function func we discussed…

In yesterday’s article, we discussed the following

• Why you should learn JavaScript
• How to Run JavaScript/Python and show output
• Variables
• Comments

Today, we will talk about the following

• Conditional Statements
• Blocks
• Comparison Operators
• Logical Operators
• Truthy and Falsy Values
• Ternary Operators
• Switch Cases

Conditional Statements

Python

Python supports the following

• if statements
• else statements
• elif statements Below is an example

num = 10if num > 20:
  print("If statement")
elif num > 10:
  print("Elif statement")
else:
  print("Else statement")

Let’s try writing the same code snippet in JavaScript

JavaScript

JavaScript supports the following

• if statements
• else statements
• else if statements — else if statements in…

As of today, April 17th, I am on day 28 and although it’s been challenging, I am looking forward to the next 72 days.

My Challenge for the 100 days

• Code at least for an hour a day
• Post content every day related to Python, SQL, or programming in general

Why am I doing this?

• I started writing articles somewhat consistently on Medium in October 2020. I want to be more consistent and build a productive habit
• Writing an article/ blog post helps me understand concepts better and drives me to learn new things.
• Increasing online presence

My Stats when I started the challenge

• Twitter — 48
• Hashnode — 9
• Dev.to — 10
• Medium — 0 people following…
