Problem 2: Apply Label Encoding with a Custom Order

Problem Description

Write a Python program that encodes an ordinal "education_level" column ("High School," "Bachelor's," "Master's") into integers that respect their true logical order (0, 1, 2).

Input

A DataFrame with an "education_level" column.

Output

The DataFrame with an additional numeric "educationlevelencoded" column.

Constraints

• Only these three education levels will appear.

Example Input

text
{"education_level": ["Bachelor's", "High School", "Master's"]}

Example Output

text
  education_level  education_level_encoded
0      Bachelor's                         1
1     High School                         0
2        Master's                         2

Concepts Covered
