Mastering Pandas: From Handling NaN and Duplicates to Advanced Sales Data Grouping

Ready to turn messy datasets into actionable insights? Pandas is the backbone of data science in Python, but reading documentation only gets you so far. You need to get your hands dirty! We've curated five beginner-friendly labs that take you from data cleaning basics to advanced boolean reductions. Whether you're a budding data scientist or a curious analyst, these interactive challenges will sharpen your skills in a real-world playground.

Handling NaN and Duplicates

Handling NaN and Duplicates

Difficulty: Beginner | Time: 20 minutes

In this challenge, you will deal with a dataset containing missing (NaN) values and duplicate entries. The main objective is to clean and preprocess the dataset by handling these NaN and duplicate values using pandas library. This challenge will test your ability to work with complex data structures, manipulate and analyze data, and make decisions based on the dataset's characteristics.
