Completed 3 lectures in my Udemy course: the second and third sections of DataFrames in the Python Pandas data library and a lecture on 'missing data' in Pandas. The first lecture/code-along was on conditional selection in tables of data and manipulating dataframes. The second lecture was on dataframe hiererachies/ the use of levels in dataframes. Finally, the last lecture covered how to deal with missing data in Pandas (e.g. null values/ empty slots)
