/0 Comments/in /by

Introduction

Are you thinking about joining a data analytics course in Delhi? If yes, then you must have heard about Python and SQL. These two tools are very important in the world of data analytics. In fact, without Python and SQL, it is very hard to work as a data analyst. But don’t worry—if you are a beginner, this article will explain everything in very simple words.

At Uncodemy, our data analytics course in Delhi focuses strongly on Python and SQL. Why? Because they are the building blocks of data analytics. Let’s understand what these tools are, why they are important, and how Uncodemy teaches them in an easy and practical way.

What Is Data Analytics?

Before we talk about Python and SQL, let’s understand what data analytics means.

Data analytics is the process of collecting, organizing, and analyzing data to make better decisions. For example, a company might want to know:

  • Why are sales going down?
  • Which product is most popular?
  • What are customers searching for?

To find answers, companies collect data. Then, data analysts use tools like Python and SQL to find patterns and trends in the data. Based on these findings, the company can make smart decisions.

Why Are Python and SQL Important in Data Analytics?

Let’s now focus on Python and SQL and why they are so useful.

1. Python – The Power Tool

Python is a programming language. It is very easy to learn and write, even if you have never done coding before. Python is popular because:

  • It has simple syntax (easy to read).
  • It has powerful libraries for data analysis.
  • It is used by top companies like Google, Netflix, and Facebook.

With Python, you can clean data, analyze it, make graphs, and even build machine learning models.

2. SQL – The Data Language

SQL stands for Structured Query Language. It is used to talk to databases. Databases store a lot of data, and with SQL, you can:

  • Retrieve data (get data from tables).
  • Filter data (show only what you need).
  • Update or delete data.
  • Combine data from multiple tables.

In simple words, SQL helps you get the right data. Python helps you analyze it.

GROUP BY product_name
ORDER BY total_sold DESC;
  1. Use Python to make a graph:
pythonCopyEditimport pandas as pd
import matplotlib.pyplot as plt

# Assume you already have the SQL data in a DataFrame
df = pd.read_csv("sales_data.csv")
