Small bug in displaying groupby with pandas data frame #59

Open Shashank545 opened 1 year ago

Shashank545 commented 1 year ago

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.
