Data Science with Python

  • Python is a multi paradigm programming language - this means that the various facets of Python are most suited for the field of Data Science. It is a structured and object oriented programming language that contains several libraries and packages that are useful for the purposes of Data Science.
  • The inherent simplicity and readability of Python as a programming language makes it a language that is preferred by data scientists. The huge number of dedicated analytical libraries and packages that are tailor made for use in data science are some of the main reasons why data scientists prefer the use of Python for Data Science projects, as opposed to any other programming language.
  • Another great thing about Python which makes it the language of choice for data scientists is the broad and diverse range of resources that are available at the disposal of a data scientist, should he/she get stuck at a particular point or problem while developing a Python program or model for Data Science.
  • The vast Python community is another big advantage that Python has over other programming languages. Since there are millions of developers working on the same problems with the same programming language every day, it is very easy for a developer to get help in resolving his/her problems because the chances are that someone else had been stuck at the same problem in the past and its resolution has already been found. If no one else has encountered a similar problem, the Python community is quite helpful and tries its best to help their fellow Data Science in Python developers.

There are many factors that make a program a success. Like every other educational field, the advancement in Data Science also depends on multiple reasons.

  • Starting with the very basic question, are you a beginner, an intermediate learner or someone with deep prior knowledge i.e. an expert? If you’re a beginner who joins an expert program, everything will go over your head. And if you’re an expert, joining a beginner’s class would feel like a waste of time and money since you’re probably aware of whatever that’s being taught.
  • Once you know what your current level is, the next question is what kind of learner are you? Whether you prefer the traditional classroom coaching where you follow a certain schedule with a specific timing or you prefer the independent style that the online coaching offers.
  • Again,one of the most important factors is money and time. Since there are endless options, you must decide which one you want according to your needs.
  • Always remember to check the reviews or talk to current or ex-students of the program, they will help you understand how the program can really help.
  • Also, before joining a full-fledged program, make sure to try a free course. It will help you firm your decision whether you are really into data science or not.

Data Science deals with identification, representation, and extraction of meaningful information, so any programming language equipped with tools to do these tasks efficiently will be naturally popular. Python is one such popular language and the reasons for the same include:

  • Short learning curve: Unlike its competitor, R, Python is comparatively easy and quick to learn due to its readable and easy-to-understand syntax.
  • Scalability: YouTube migrated to Python due to its efficient scaling capabilities. As compared to its competitors - R, MATLAB etc., Python has a significant lead in scalability due to the flexibility it provides during problem-solving.
  • Libraries: Python is the leading language for machine learning projects due to the packages it offers to the developers. Packages like pandas, scikit-learn, etc. allow for ML algorithms to be applied to the data easily.
  • Data visualization: With the help of matplotlib, Python enables us to plot complex data representations into 2D plots. Data visualization is a significant process in the job of a data scientist. With the help of Seaborn, ggplot etc. along with matplotlib, Python provides us with a great data visualization tool.

As data science is a huge field and involves multiple libraries to work together in a smooth way, it is essential that you choose an appropriate programming language.

  • R: Although it has a steep learning curve, it has various advantages.
    • The big open-source community that provides R with high-quality open source packages.
    • Includes loads of statistical functions and handles matrix operations smoothly.
    • Via ggplot2, R provides us with a great data visualization tool.
  • Python: Though it has fewer packages than R, Python is still one of the most sought after languages in the data science field.
    • Pandas, scikit-learn, and tensorflow provide with most of the libraries needed for data science purposes.
    • Easy to learn and implement it.
    • It has a big open-source community as well.
  • SQL: SQL is a structured query language which works upon relational databases.
    • Pretty readable syntax.
    • Efficient at updating, manipulating and querying data in relational databases.
  • Java: Even though it has less number of libraries for data science purposes and with Java’s verbosity limiting its potential, it has many advantages as well:
    • Compatibility. Systems are already coded in Java in the backend, and its therefore easier to integrate Java data science projects to it.
    • It is a high-performance, general purpose, and a compiled language.
  • Scala: Scala runs on JVM and has a complex syntax. Still, it is a preferred language in data science domain due to the following advantages:
    • As it runs on JVM, any Scala program can run on Java as well.
    • When used along with Apache Spark, we get high-performance cluster computing.

Follow these steps to successfully install Python 3 on windows:

  • Download and setup: Go to the download page and setup your python on your windows via GUI installer. While installing, select the checkbox at the bottom asking you to add Python 3.x to PATH, which is your classpath and will allow you to use Python’s functionalities from terminal.

Alternatively, you can also install Python via Anaconda as well. Check if Python is installed by running the following command, you will be shown the version installed:

python --version

  • Update and install setuptools and pip: Use below command to install and update 2 of most crucial libraries (3rd party):

python -m pip install -U pip

Note: You can install virtualenv to create isolated Python environments and pipenv, which is a Python dependency manager.

You can simply install Python 3 from their official website through a .dmg package, but we recommend using Homebrew to install Python as well as its dependencies. To install Python 3 on Mac OS X, just follow the below steps:

  1. Install xcode: To install brew, you need Apple’s Xcode package, so start with the following command and follow through it:$ xcode-select --install

  2. Install brew: Install Homebrew, a package manager for Apple, using following command:/usr/bin/ruby -e "$(curl -fsSL)"Confirm if it is installed by typing: brew doctor

  3. Install Python 3: To install latest version of python, use:

brew install python

  1. To confirm its version, use: python --version

You should also install virtualenv, which will help you create isolated places to run different projects and may run even on different python versions.

Follow the below steps to successfully install Python 2 on your windows:

  1. Download the MSI file from the official download website and go through its GUI setup.
  2. Suppose you have installed Python 2.x, so windows would create a folder 

C:\Python2x This helps in installing multiple versions of Python on your windows machine.

  1. To use python command line from terminal, go to Control Panel > System > Advanced system settings > Environment variables. Add C:\Python2x; (with semicolon) to the PATH variable value and click OK.
  2. Restart the command prompt and type the following to see the installed python version: Python --version

Unstructured data refers to the undefined contents of a data set that cannot be fit into structured database tables. It is basically information that is not organized in a predefined manner nor has a data model that is pre-defined. Unstructured data is generally text-heavy but may also consist of other data such as numbers, facts, figures, audio, video etc.

While unstructured data may be difficult to organize, if a company is able to tap into it in a meaningful and efficient manner, it is like digging up a bag of gold.Unstructured data can aid companies in the formation of important business decisions if a company is able to integrate this unstructured data into their information management systems and landscapes.

Pandas and NumPy are two of the most used Python libraries for data manipulation. Most of the times they are used in a single project. Although Pandas is a library build directly off from NumPy, there are some differences between both of them.

Differences

Pandas

NumPy

Data input

Tabular form - CSV or SQL formats

Numerical data

Main feature

Helps add, edit, or create columns or rows to the table.

Helps perform multiple operations on Array.

Building block

Series which is built off from ndArrays of NumPy.

ndArrays - Allow mathematical operations to be vectorized and when compared to Python lists, they are stored with much better efficiency.

Ways to access data

We can use labeled data - integers as well as numbers to label the elements of the series object.

Only integers are used for labeling the elements.

The content was sufficient and the trainer was well-versed in the subject. Not only did he ensure that we understood the logic behind every step, he always used real-life examples to make it easier for us to understand. Moreover, he spent additional time to let us consult him on Data Science-related matters outside the curriculum. He gave us advice and extra study materials to enhance our understanding. Thanks, Knowledgehut!
