This article is all about getting to know the most in-demand, powerful, and useful machine-learning language, Python!!! Well, if you are a newbie trying to explore the best data analytics tools, what can be the best tool than python? Today we will be discussing python and how you can master this programming language. So, letís understand the basics of python.

It will be a great idea to gather some information in general about python before you decide to explore this machine-learning language. The main reason why python is such a popular programming language is that it is not just a general programming language but is also adopted in scientific and machine learning. If you are amid programmer or have a good interest in learning machine learning languages, Python is the right choice.†

Go for itÖ! Install python and begin the exciting programming journey.

It will be a good idea to install python, as both scientific learning and machine learning languages will be used. Install Anaconda, which is open-source software that developers focus on. Python is compatible with Linux, Windows, and OSX. But†what Python is all about? Letís understand it quickly:

  • It is easy enough to be learned by non-technical or experienced programmers.†
  • It is very versatile and can develop complicated software.†
  • The software expertise can take you to different levels altogether, from a python user to a Python ecosystem controller.
  • It is compatible and open to many platforms.

What is Python for Data Science?

Python syntax is an easy and interesting programming language. Having some programming background or statistics, and mathematics knowledge is a good sign. With little or no coding experience with such a background, you can still try your hand at python.

Python is an open-source language which means it is for all and a free tool, which you can download and can, explore.†Python is the most popular language amongst developers. The python libraries make data science coding easier. A python library makes coding simple and easy with its prebuilt data science coding. Many languages in data science have coding and programming which is complicated and has to do all tasks from the scratch. Python library gives you a free hand and creative flee to define the required output.

To name a few, the most preferred libraries by developers are NumPy, Matplotlib, Scikit-learn, Apache Spark, pandas, TensorFlow, and many more.†††Let us know some of them which will help you understand python better.

TensorFlow :

It is an open-source library used for high-end calculations. It is also used in machine learning and deep learning algorithms. It contains a large number of tensor operations. It is a Python library that is used to solve complex calculations in Mathematics.

NumPy:

It is used for a lot of mathematical tasks, linear algebra routines, multidimensional arrays, Fourier transform, and matrices. It is an open-source program that is free to use. The crux of NumPy is well-optimized C code. Enjoy the compliance of Python with the speed of assembled code.

Matplotlib:

Visualize in python with matplotlib. It is a data visualization and graphical library for python. It makes your visualization task simple and clear to reach the audience. It creates interactive or static line graphs, boxplots, bar charts, etc. matplotlib offers an open-source alternative to MATLAB. Developers use the application programming interfaces to insert plots in graphical interfaces.†

You can download matplotlib as a binary package from the Python Package Index (PyPI), with the following command: python -m pip install matplotlib.

PyTorch:

PyTorch is the largest machine-learning library that optimizes tensor calculations. It has high-end APIs to perform tensor computations with strong GPU acceleration. It is highly efficient to solve application issues related to neural networks.

Pandas:†

It is the most suitable and favored library in python. The developers credit pandas when it comes to data science, data analysis, or machine learning tasks. It performs smoothly the data cleaning and data analysis tasks with easy tabular data manipulations.†

SciPy:

The name ďSciPyĒ stands for ďScientific PythonĒ. It is an open-source library used for high-end scientific calculations. This library is built over an extension of Numpy. Numpy allows sorting and indexing of array data, the numerical data code is stored in SciPy. It is most preferred tool used by developers.

  • Pandas are suitable for a wide range of data types.†
  • Tabular data with contrast and composite columns, as in SQL or Excel spreadsheet.†
  • Structured and unstructured data with not very flexible frequency.††
  • Irrational matrix data with row and column labels.
  • All forms of data from visual to statistical data sets. It is acceptable even if data is not labeled to be placed into the panda's data architecture.

Pandas are exclusively used in the production of financial applications. The most convenient way to install pandas is to install them as part of the Anaconda distribution, a cross-platform distribution for data analysis. This is the most recommended installation method for developers.

How To Master Python For Data Science?

So what can be the interesting ways you would like to know about getting proficient in python?†

1. Know your Reason to Master Python

You must be very clear with your perspective on python, as to why you want to get into it. If your purpose is clear your further journey will be quite interesting and meaningful.††
There can be situations during the learning process which can be a bit frustrating. The code re-writing and dubbing the errors can be quite mind bogeying. Under such a plight to keep your mind clear and focused, just find out the reasons you want to learn python.

  • You are interested to know in which field, python is applied?†
  • Are you simply learning python to upgrade your skills?†
  • Are you willing to get a job/stream change that is python based?†
  • How much time, you are ready to invest to understand python?
  • Once you are clear with your perspective you are free to choose python and move ahead to make a remarkable journey ahead.

2. Get Started with the Fundamentals

Yes, python is an easy language to understand. You must know that it is not easy to move further with a simpler or casual approach. This journey to know python can be quite a roller coaster. Get ready for an exciting ride. The basics of python are the foundation of data analysis.

String functions are used to manipulate text in multiple ways.† For instance, string operational functions can be found complex and you may wonder where to use them exactly. When you start working on text data like social media posts. The initial part is to get a data cleanup process in order. Text cleanup includes tasks like noise removal, removing extra spaces, punctuation marks, and unnecessary symbols; maintaining the lowercase text pattern all over.

Introduce yourself to Jupyter! Jupyter supports over 40 programming languages, including Python, R, Julia, and Scala. Jupyter is the most interactive integrated Development Environment. It is a software application for editing source code, and building, and debugging programs.

You have to invest time in learning the types of data structures available in python. The operational data structures, the variables, and conditional flows. The inbuilt functions of python such as map-reduce and filter are unique.†
