EDA Python - 18-Pandas_2

The video tutorial covers the use of various Python modules like Seaborn, NumPy, Pandas, and Matplotlib for analyzing WHO COVID-19 data. It demonstrates data loading, cleaning, and preparation, including handling whitespace and converting strings to datetime. The tutorial also explores plotting techniques using Seaborn and Pandas, data manipulation like sorting and reindexing, and time series analysis. The video concludes with practical examples of plotting daily COVID-19 deaths in the US and UK.
