So in 01 - Data Exploration.ipynb notebook we have
print(df_students.groupby(df_students.Pass)['StudyHours', 'Grade'].mean()) , but this gives an error below.
ValueError: Cannot subset columns with a tuple with more than one element. Use a list instead.
Solution:
Change it to print(df_students.groupby(df_students.Pass)[['StudyHours', 'Grade']].mean()) to fix and resolve it.
Note:
A very small but important fix.
