There are over 250 computer programming languages in the world. And on top of it, there are frameworks and libraries to add further to them. Then why is Python the programming language of choice for data scientists? What features of the Python language give it an edge over the other languages? Let’s figure it out in this blog today.
Python is an open-source, free, dynamically typed, high-level, interpreted, scientific programming language developed by Guido van Russom. It is a general-purpose cross-platform object-oriented language that can be used in multiple fields such as machine learning, data science, artificial intelligence, web application development, building games, automating processes, etc.
As many as 93% of the data scientists are reported to have been using Python language according to a Kaggle survey. Nearly 24,000 professionals in the data science field were asked for their opinion on different programming languages and their reason for choosing Python over R or SQL. Here are the top reasons why Python is the most sought-after programming language for data analysis.
Python is one of the easiest languages to learn and code. With its great readability and massive libraries, it offers immense flexibility to the developers to handle complex tasks efficiently.
Python is an expressive language. Meaning, a three-line code in Java or any other programming language can be written as a single line of code in Python.
Python is an interpreted language. An interpreted language means that each line of code is executed one at a time, making the process of debugging easier.
A wide range of packages can be used for scientific programming like Pandas, sci-kit learn, Numpy, Matplotlib, Seaborn, etc. for data science and data visualization in Python.
Python can be easily integrated with various programming languages like C, C++, Java and can be run line by line as is the practice in Python for quick debugging of complex code.
Python can embed other programming language code for easy implementation of certain functionalities within Python code.
Python offers automation frameworks like PyUnit for effortlessly creating unit tests. Developers without a Python background also can work with unit testing using this module quite easily. Moreover, the test reports are also generated within milliseconds.
Among all the programming languages available today, Python is popular for its scalability. Python offers flexibility which is useful for any complex app development.
Python’s community is acknowledged worldwide. The community helps in easy learning of Python language, helps in bug fixes, troubleshooting, and simplifies the learning path for newbies.
Data Science is a broad field of computer science that involves various steps from data collection, data cleansing, Exploratory Data Analysis (EDA), Data modeling, data visualization, and report generation. All the below-mentioned steps can be carried out using various Python libraries or integrating with other tools for best results.
1. Data Collection and Cleansing : Python can deal with almost all sorts of data from different file formats such as CSV, TSV, JSON, etc. The libraries like PyMySQL can help import SQL tables directly into the IDE for easy cleansing of data. It can help the developers detect any missing values for extracting and replacing the missing values.
2. EDA (Exploratory Data Analysis) : Once the data is collected and cleansed, fitted with the right replacements for null values, it is time for standardizing the data. You can explore and segregate the data into different types such as numerical, date, categorical, nominal, etc. for normalizing the data. The next step is to use the NumPy and Pandas libraries in Python to draw insights, identify patterns, in the data to manipulate them for best results.
3. Data Modeling : This step is the most crucial part of data science. Various algorithms like Naïve-Bayes, K-Means, decision trees, can be used to train datasets to classify or predict the test data based on the training.
4. Data Visualization and Report Generation :
Python’s data visualization packages like Matplotlib, Seaborn can be used to generate interactive graphs, charts, for data visualization and report generation which is a critical step of data science.
As data visualization, data presentation and reporting are imperative to data science, Python creates beautiful presentations for business use cases or integrates with Tableau or Power BI for generating reports.
Python programming language helps in the end-to-end data science projects and various tech giants embrace Python for the various benefits it offers which we discussed in the previous sections. To sum it up, Python is easy to learn and code but at the same time has the potential to deliver complex projects quickly and efficiently.
