Task

Here is the 'students.csv' dataset, which contains 4 columns, 3 of which are categorical. Your task is to process this dataset and encode all categorical variables.

  1. Determine for which columns to use ordinal encoding, one-hot encoding, and for which label encoding.
  2. Convert columns.
  3. Output the dataset.
