SQL Vs Python

Knowing how to utilize popular programming languages is beneficial for data scientists, computer programmers, developers, and machine learning engineers since data arrives in a variety of formats. Various certifications such as best machine learning course, data science course, software development course, etc are available online.

SQL and Python are two popular programming languages. If you want to pursue a career in computer science, you should understand the distinctions between these programming languages, as well as their benefits and limits. In this post, we compare SQL and Python, explore when to use each, and explain which to learn first if you want to pursue a career in computer science.


SQL (Structured Query Language) is a programming language that allows programmers to manage and retrieve data from databases, as well as design their own databases. Many businesses store information in relational databases, which employ tables, columns, and rows to arrange data and link data between tables. SQL is frequently used to create and maintain these databases.

SQL may also be used by developers to provide rapid data insights, execute data studies, and extract records from large databases. Data saved in databases may be used by web pages, apps, and business software packages. SQL course help developers deal with a variety of databases, including:

  • Databases for banking
  • Applications for social media
  • Software for making music


Python is a general-purpose programming language, which means it can be used for a wide range of applications. Back-end development, software development, and developing system scripts are just a few of the responsibilities. Python is commonly used by data scientists because of its simple syntax and widespread use in the industry, making it easier to work with other data scientists while creating data analysis tools.

Python has become one of the most popular languages for data exploration due to its flexibility to function on a variety of platforms and its emphasis on readability. Python-based software, apps, and programs are used in a wide range of sectors because of their adaptability. General web development, data analysis, and machine learning are among the applications for Python. Machine learning is a type of artificial intelligence that focuses on constructing computer algorithms that learn from experiences rather than human code changes.

SQL Vs Python

The main distinction is that SQL is primarily used for accessing and extracting data, but Python is a general-purpose programming language that allows for data exploration. So, which language do you think you should study first? Let’s look at an example to see how they compare.

Assume you have a database table called “eateries” that contains data about a number of restaurants. There may be millions of entries in this table, each representing a separate restaurant. Name, city, address, prices, rating, contact information, and so on would be included in each row. Let’s compare how SQL and Python may be used to query this dataset.

With the SQL statement SELECT* FROM eateries, you may get a list of all the restaurants. Similarly, you may use SELECT* FROM eateries LIMIT 5 to get the first five restaurants. The SQL query SELECT Name FROM eateries may also be used to gather the names of all the restaurants in Mumbai. WHERE ‘Mumbai’ is the city.

The following lines, on the other hand, may be used to extract the same information in Python using Pandas:

All restaurants: eateries

First five restaurants: eateries.head(5)

Restaurants in Bangalore: eateries[eateries.City = = ‘Bangalore’].Name

You’ll see that the two languages are pretty similar in the example above. However, when we construct more complicated queries, things begin to change.


With just a few exceptions, we can demonstrate that SQL is usable in relational databases based on the reasoning presented above. For beginners, though, it may still be a useful tool. Many additional features have been added to SQL over the years to increase its object-oriented capability. On the other hand, Python is a flexible and dynamic programming language with a wide range of uses. Its vast reach may be ascribed to its large collection of data science python libraries, each of which serves a particular function.



Writing has always been a big part of who I am. I love expressing my opinions in the form of written words and even though I may not be an expert in certain topics, I believe that I can form my words in ways that make the topic understandable to others. Conatct:
