Introduction

In the age of big data, clean and structured data is gold. Whether you are a data scientist, analyst, or developer, knowing how to prepare data effectively is essential. This process, known as data wrangling, involves transforming raw data into a format that's usable for analytics. In Pune, one of India’s leading IT hubs, learning data wrangling with Python can give you a competitive edge in the data-driven job market.

What is Data Wrangling?

Data wrangling—also known as data munging—is the process of cleaning, organizing, transforming, and enriching raw data into a structured and usable format for analysis or machine learning.

It typically involves steps such as:

• Removing missing or duplicate values

• Filtering and correcting inconsistent data

• Transforming formats (e.g., date/time, text)

• Merging multiple data sources

• Restructuring or aggregating datasets

In Python, data wrangling is commonly done using powerful libraries like:

• pandas – for data manipulation and analysis

• numpy – for numerical operations

• openpyxl or xlrd – for Excel files

• json, csv, re – for parsing formats

• beautifulsoup4 and requests – for scraping and wrangling web data

Importance of Data Wrangling in Data Science

Without proper data wrangling, the quality of insights drawn from data analysis may be compromised. Data wrangling ensures:

• Consistency across datasets
• Improved accuracy of analysis
• Faster and better decision-making
• Efficient use of data pipelines
