Choosing a programming language over another in the big data field is very much project specific and depends on the project goal. However, whatever may be the goal Python and Big Data is an inseparable combination when we consider a programming language for big data development phase.
It is a crucial decision because once you start developing your project in a language, it is difficult to migrate in another language. Moreover, not all big data projects have the same goal. For example, in a big data project, the goal may be simply manipulating data or building analytics while in others it could be for the Internet of Things (IoT).

As Python is a high-level language, it has many benefits which accelerate the code development. It enables prototyping ideas which makes coding fast while maintaining the great transparency between code and its execution. As a result of the code transparency both the maintenance of the code and the process of adding it to the code base in a multi-user development environment becomes easy.
Python is an object-oriented programming language which also supports advanced data structures such as lists, sets, tuples, dictionaries and many more. It supports many scientific computing operations like matrix operations, data frames, etc. These abilities within the Python enhance the scope to simplify and speed up data operations.
Data Processing Support
Python provides advanced support for image and voice data due to its inbuilt features of supporting data processing for unstructured and unconventional data which is a common need in big data when analyzing social media data. This is another reason for making Python and big data useful to each other.

5 Reasons why Python is Perfect-fit for Big Data
Python is considered as one of the best data science tool for the big data job. Python and big data are the perfect fit when there is a need for integration between data analysis and web apps or statistical code with the production database. With its advanced library supports it helps to implement machine learning algorithms. Hence, in many big data aspects, Python and big data complement each other.
1. It’s a bag of powerful scientific packages
Python big data combination is backed by its robust library packages which fulfill analytical and data science needs and makes it a popular choice in big data applications.
Some of its popular libraries which make Python and big data useful together are:
Pandas is a library which helps in data analysis. Besides that, it provides the required data structure and operations for data manipulation on time series and numerical tables.
NumPy is the fundamental package of Python which makes possible scientific computing. It provides the support for linear algebra, random number crunching, Fourier transforms. Also, it supports multi-dimensional arrays, matrices with its extensive library of high-level mathematical functions.
SciPy is a widely used library in Big data for scientific and technical computing. SciPy contains different modules for

- Interoperates with the Python libraries like NumPy and SciPy.
TensorFlow is an open-source software library supported by Python for machine learning for a range of tasks. The library is capable of building and training neural networks to
- Detect patterns
- Decipher patterns
- Analogous for the purpose of learning and reasoning.
Python with the libraries mentioned above makes big data scientists’ life easy. For example, with Python library integration with Spark and Scikit-learn data scientists can write code and test with small data sets before it is implemented on Spark cluster. Once the code is verified and works with its desired functionality, they can implement the same on the Spark cluster with a large set of data. This helps to escape them from repetitive code cycles and accelerate business decisions.
There are a number of myths all around regarding Big Data. Let’s go through some common Big Data Myths and Facts behind them.
To use any library, scientists need to search online by tagging ‘Python + [required analytics tool].’ This shows up the testing code with the analytics and required documentation for it along with examples as guidance.
2. Compatible with Hadoop
Hadoop is one of the best Big data tools. As Python big data is compatible, similarly Hadoop and big data are synonymous with each other. Hence, Python has been made inherently compatible with Hadoop to work with big data. Python consists of Pydoop package which helps in accessing HDFS API and also writing Hadoop MapReduce programming. Besides that Pydoop enables MapReduce programming to solve complex big data problems with minimal effort.
3. Easy to Learn
Python is easy to learn as it abstracts many things with its features. As a result, user needs to code fewer lines of code. Besides that it has scripting feature as well. Python is coupled with user-friendly features like code readability, simple syntax, auto identification and association of data types and easy implementation.
Scalability matters a lot when you are dealing with massive data. Unlike other data science languages like R, MatLab or Stata, Python is much faster. Though there was initial complain about its speed, however, with Anaconda its speed performance has enhanced a lot. This makes Python and big data compatible with each other with a greater scale of flexibility.
5. Large Community Support
Big data analysis often deals with complex problems which need community support for solutions. Python as a language has a large and active community which helps data scientist and programmer with expert support on coding related issues.This is another reason for its popularity.
