How Can I Become a Data Scientist with Python?

14-Jun-2021

These days, we hear so much about Data Science! We would not be wrong here to write more on a topic - that harps about this big and major field of Data Science that has changed and revolutionized the whole technological world of the 21st century!

To start with, Data Science, we would like to define it. You must know what Data Science is. This is necessary to have a better grasp of the job role of a Data Scientist, currently. Let’s define it:

Data Science is all about analyzing and examining various structured and unstructured data sets for companies to make better and reliable business decisions. Here, the role of a Data Scientist is to use various techniques and algorithms to understand data and bring out data insights for employers, so that they can assist their clients and customers in a way they - the buyers - want to be fetched and served!

Data Science is nothing, but a way of studying old data patterns and predicting and forecasting new frameworks. For this, Python is a serious breadwinner! Python is the most uncomplicated simple programming language that can be used by Data Scientists.

It is a free open-source language. Understanding how significant python is, we have many data science with python certification training available in the educational market, today!

The Job Position of a Data Scientist - Hottest Job of 2021!

Why is there so much hype for the job role of a Data Scientist? Why is every other learner keen on taking up the job role of Data scientist in any of the top-notch organizations? The answer is here -

The data is being produced at such an enormous rate, daily that to operate on such huge data sets organizations need more trained and skilled data scientists. Companies require competent, and talented data scientists because, they help enterprises in recognizing, extracting, and using some valuable data insights. These are then employed for building more productive business strategies, plans, and models.

No doubt, the job opportunity for Data scientists is expanding at an alarming rate worldwide! This will increase more in 2022 and 2025. Majorly, the most basic skill for a data scientist’s job is working with SQL. If you know SQL you can make it to many entry-level positions. But, the ultimate nutcracker is Python!

Let’s look which companies hire Data Scientists with a more deep knowledge of Python -

• Microsoft: Microsoft hired 1,623 high-Level data workers.
• IBM – IBM selected 1,245 High-level data personnel.
• Facebook – Facebook recruited 1,307 superior data employees lately.
• Amazon – Amazon hired 1,215 top-level data employees.
• Apple – Apple recruited 385 senior-level data employees.
• Google – Google had 904 top-level data workers openings.

These enterprises give more weightage to the candidates who have earned the best data science with python certifications and have up skilled and trained themselves to the core!

Become Data Scientist with Python

1. Learning Python with Data Science

This is the first step towards becoming a data scientist. Python is the most common programming language that makes it easy for data scientists to code and program hassle-free. With its ready-to-use easy syntax, Python is visualized as the most suitable language for any coder or programmer who is developing a code or a program with particular software, machine, robot, or device.

It is noted for its versatility. It is first and fore mostly supplied with powerful libraries. These are - NumPy, SciPy, and Pandas. These help in data analysis and assist in various other tasks committed in Data Science.

2. Learning Statistics

While studying and learning Data science, we use statistics as a method of examination. It is a way of interpreting, evaluating, and analyzing big and huge data sets. We cannot ignore statistics as it is the best way to gather insights, reach potential outcomes and goals with an error-free prediction and forecasting with the data.

This is helpful for a firm to understand the business market and hence, its independent position in terms of profit in the marketplace. Thus, we can say that Statistical analysis allows data scientists and firms to acknowledge hidden details from huge datasets.

3. Collection of Data

This part of becoming a data scientist involves the importation of relevant data from various sites, local portals, and CSV files. It includes bringing in data from various websites, using the Python library. It involves huge scrapping. Here, Python plays a major role in the collection of useful data. It is through ETL pipelines in Python, that the data is collected and managed.

4. Cleaning Data

Data scientists tend to donate more time while executing this operation. It is a major step as it demands, a critical evaluation of raw data. Picking up useful data, which can be used as a basis for conducting better deeper research with the real and best data, is an emphasis. 

What Data scientists do is remove undesired values, absent and missing values, categorical values, wrongly submitted records, and outliers, from a fresh and underdone form of data. Data Cleaning is an utmost significant character as it envisions that real-world data is tangled in nature.

As it can be really hard for data scientists to deal with complicated raw data, various python libraries like Pandas and NumPy, come to the rescue. Thus, Python libraries play a vital role while assisting a Data scientist to clean heaps of data for more accurate and better business insights and decisions.

5. The Role of EDA - Exploratory Data Analysis

It is inclusive of Data Visualization, Manipulation, and Analysis. It comes into play when various Machine learning algorithms fail to recognize various data patterns, variables, trends, to bring out other useful insights. It involves many graphical and statistical methods.

6. Machine Learning and Deep Learning

It is the most chief and vital skill for Data Scientists. Machine learning is employed to assemble many classification and predictive models. Machine learning is used by many big and top firms and enterprises to effectuate planning models as per various forecasts and predictions.

On the other hand, Machine learning is a subset of machine learning, but more effective and better in modern ways of analysis and examination of data. It employs neural networks that help train data.

There are two types of neural networks that are used by Data scientists - Recurrent neural network (RNN) or a convolutional neural network (CNN). For instance, face recognition, and speech recognition is a better example of deep learning and machine learning.

7. Deploying and Positioning ML models

Here, the ML models are brought into use in a wide practical business environment. It is implemented in a vast business set up to note the practical implications of the device or model.

The deployment of ML models prepares end users to have their hands on the model or a device. This is done by integrating the models in the different production environments. For instance - MLOps, Google Cloud, Microsoft Azure, Flask, Heroku are some examples of ML models.

8. Testing in a Real-World

To check if the model that was earlier deployed in a real-world surrounding is working with the right accuracy and effectiveness, the model demands real testing and trial. It is the most significant step for a Data scientist to keep a check upon the efficiency and effectiveness of the ML model. Testings like A/B, AAB Testing, etc are the most used testing methods used by data science professionals in the world of IT.
