Download the Titanic passenger list from Kaggle. Use Pandas to load the CSV. Use df.isnull().sum() to find missing ages. Use Matplotlib to plot a histogram of passenger fares. Fix the missing ages using the median. Phase 3: The Wrangle (90% of the Real Job) Data is never clean. It arrives with null values, duplicates, inconsistent capitalization ("New York" vs "new york"), and impossible outliers (Age = 999).
But sitting down to learn Python for data science often feels different than learning Python for web development. You don’t need to build a video game or a social media platform. You need to clean messy spreadsheets, run statistical tests, and build machine learning models.
The crash course starts now.
