Data Science is all you can see all over the internet, it might be job vacancies or training from the various institutions. Data Scientists’ requirements growing day by day and with the need the availability of Data Scientists is insufficient. Data Scientist needs to do coding, so he should learn a programming language. Python is the best programming language and mostly used by Data Scientists.

Python helps developers to build programs and prototypes, thereby speeding up the development process. When a project is about to become an analytical tool or application, more advanced languages such as Java or C can be translated if needed.

The simple use that makes Python available means that new data scientists tend to be drawn towards Python. So famous actually, Python’s favorite programming language is estimated by a whopping 48% of data scientists with five or having less than a few years of experience.

This number increases with increasing experience and the study is increased. For data scientists, Python has proved to be a fantastic starting point.

Python has been known for years as a simple programming language, however from a syntax standpoint. Python has a vast selection of libraries and resources as well. The outcome? You have a platform for programming that is useful for emerging technologies like machine learning and data science.

Professionals working with applications in data science do not want to get involved in complicated programming. You want to use programming language like Python, which are easy and anybody can use.

But why programmers go for Python and why it is loved and also why Data scientists need to learn Python. Let’s see the reasoning

Now let’s see the most basic needs for Data Science. Let us now consider the steps for solving Data Science processes for problem-solving that includes

  • Data collection & cleansing
  • Data exploration
  • Data modeling
  • Data visualization & interpretation

Data collection & cleansing

Python allows you to play with virtually all forms of data that is available in various formats, such as comma-separated value (CSV), tab-separated value (TSV), or web-based JSON.

Python will help you accomplish certain tasks easily with dedicated Python libraries, such as PyMySQL and BeautifulSoup, if you want to import SQL tables directly into your code or whether you want to scrap a site. First you can easily connect to a MySQL database to run queries and extract data, and second, read XML and HTML data. You will also need to take care of missing data sets during the data cleaning process and substitute values accordingly after extracting and replacing values.

If you ever get caught with a specific dataset, the powerful and dynamic Python community helps you find a solution by doing your Google search for that dataset and Python!

Data exploration

Now that the data are collected and sorted, ensure that all collected data are standardized. Now that you have clean data, find out the market problem to be addressed and turn it into a topic of data science.

In order to provide the required care, exploring the data to recognize and segregate their properties into various types such as numerical, orderly, nominal, categorical, etc.

If you categorize data by sort, NumPy and Pandas, the Python libraries for data analysis can allow you to unlock knowledge from data by manipulating it quickly and effectively.

It’s time to start AI and machine learning for data modeling now that the data is ready to be used.

Data modeling

This is a very important stage in the process of data science in which you try to minimize the data set dimensionality.

Python has several specialized libraries to help you tap the strength of the computer to carry out data modeling tasks.

Do you want to analyze the data numerically for modeling? Get in your toolkit with NumPy! SciPy allows science computation and calculations to be carried out easily. The Scikit-learn code library provides you with an intuitive and complex interface to apply machine-learning algorithms to your results.

When data modelling has stopped, data for actionable observations can be visualized and interpreted.

Data visualization & interpretation

The data visualization packages in Python are various. Matplotlib is the most commonly used library for simple graphs and charts. If you need advanced graphs that are beautifully built, you can try another library from Python, Plotly.

Another Python library, IPython, facilitates the visualization of interactive data and the use of a GUI toolkit. If you choose to insert your results in interactive Web pages, it will help you transform a wealth of HTML snippets from IPython or Jupyter.

After data visualization, it is extremely important to present the data and to make the results such that they are informed by the business questions you asked at the outset.

Now that you have the answer to your business questions and practical observations, you should note that your interpretations sound beneficial to your organization’s stakeholders.

Either predictive causal analysis or predictive analysis, Python has the tool to perform many powerful functions, regardless of what scientists are trying with Python. No wonder why Python was adopted by data scientists.

If you are Data Scientist you might be aware that you need to deal with numerous data, that needs to be processed to gain insight. In order to process data, we need algorithms that are easily available or developed with Python.
